- a remote sensing module 900 can be provided to serve as a sensor data logger, and to communicate to receive additional sensor information, and/or to forward sensor information to other devices or networks.
- the various sensor functionality may be implemented in a removable chip or card, as illustrated in FIGs. 7, 8A, and 8B. While the present invention may be utilized with any removable or fixed circuit operable with a mobile device, one embodiment of the present invention involves the implementation of the sensor functionality in a removable card, such as a MultiMediaCard (MMC).
- MMC MultiMediaCard
- MMC refers to a data storage and communication media that exhibits high mobility and data throughput, while consuming relatively low power.
- MMC communication is based on a serial bus having a particular communication protocol generally referred to herein as MMC mode.
- MMC cards may also offer an alternate communication protocol that is based on the SPI standard, or other standards.
- SPI serial protocol
- MMC cards may also offer an alternate communication protocol that is based on the SPI standard, or other standards.
- Standard MMC communication signals include a clock (CLK) signal, a command (CMD) channel, and a data (DAT) channel.
- CLK clock
- CMD command
- DAT data
- the CLK signal is used to synchronize data transfers across the bus.
- the CMD is a bidirectional command channel used for card initialization and data transfer commands.
- An open-drain operational mode is typically used for initialization, and a push-pull operational mode is typically used for command transfer. Commands are sent from the master (e.g., host process) to the card, and card "responses" are provided from the card(s) to the host.
- the DAT channel is also a bidirectional channel, which operates in push-pull mode.
- MMCs can come in different categories such as Read-Only Memory (ROM), Read/Write (RW), and Input/Output (I/O).
- ROM Read-Only Memory
- RW Read/Write
- I/O Input/Output
- MMCs include a set of information registers.
- the registers include a card identification number (CID), which is a unique number for the card.
- a relative card address (RCA) register is dynamically assigned during initialization, and identifies the local system address of the card.
- the card specific data (CSD) register provides information about the card operation conditions.
- the driver stage register (DSR) is optionally used to configure the card's output drivers, and the operation condition register (OCR) optionally provides a voltage profile for the card, to identify cards that do not support the full voltage range.
- the MMC bus is a single master bus with a variable number of slaves.
- one embodiment of the invention implements a new "multimaster" concept, thereby allowing for the possibility of other devices, such as the sensor module, to access the memory of the MMC card. Such an embodiment would involve, for example, a situation where the sensor module is attached to the master process, but the module is still operating as a data logger. In this mode, a bridge allows the sensor interface and the master process to access the same memory.
- the bridge in accordance with the present invention provides functionality to avoid conflicts between writing to and reading from the same memory.
- the bridge functionality in accordance with the present invention can maintain hardware and software compatibility with an MMC memory card, and uses the MMC bridge concept to connect other busses or controllers/processors within the MMC card to the MMC bus.
- this microcontroller may need to access the memory included in the MMC card, and the bridge functionality facilitates such memory access, while resolving possible conflicts on the MMC bus.
- the MMC bridge architecture in accordance with the present invention includes at least two types, referred to herein as a standard bridge type and a multimaster bridge type.
- the standard or multimaster bridge is connected between the memory die and the interface pads of the MMC card, where the MMC card is basically a printed wiring board (PWB) used to interconnect the various dies molded within a package.
- the bridge can monitor and intercept exchanges on the MMC bus between the MMC host and the memory.
- a sensor module or other component
- the bridge monitors the exchanges on the bus. When finding requests targeted to the sensor module, the bridge can redirect them to the sensor module, and vice-versa. The bridge also ensures otherwise normal operation between the host and the MMC.
- the implementation complexity of the standard bridge type is relatively low, as it does not require a full MMC controller implementation - rather, the MMC controller of the memory die can handle all of the MMC protocol.
- the standard bridge will implement a small subset of the MMC commands that allow access to the sensor module.
- the bridge places the MMC memory in parallel with some other device, such as the sensor module, without interfering with the MMC memory.
- the MMC host is equipped with a software module to recognize the "added value" MMC (e.g., memory plus sensor MMC), which allows the host to use both the memory and the sensor functionality.
- FIG. 10 is a block diagram illustrating an example of such a bridge implementation in accordance with the present invention.
- the illustrated embodiment includes an MMC host 1000, a memory 1002, and another component 1004 such as an Application-Specific Integrated Circuit (ASIC), microprocessor/microcontroller, etc.
- the component 1004 represents a sensor module in accordance with tlie present invention.
- a bridge, the MMC bridge 1006 in this example, is logically coupled to each of the host 1000, memory 1002 and sensor module 1004.
- the bridge 1006 may communicate with the memory via MMC interfaces 1008, 1010, and may communicate with the host via MMC interfaces 1012, 1014.
- the interface 1016, 1018 may be any type of interface, depending on the type of component al04 that is present in the system.
- FIG. 11 illustrates a more particular embodiment of an MMC bridge implementation in accordance with the present invention.
- the MMC bridge 1100 and sensor functionality 1102 are provided in a common bridge block 1104.
- the bridge block 1104 provides an interface to internal registers 1106 and to the MMC card 1108 (e.g., FLASH/ROM) from the same MMC host interface 1110. Interrupts are sent from the sensor functionality 1102 to the interrupt control 1112, which in turn generates a bridge interrupt signal and an interrupt vector.
- the various signals and corresponding signal types, sizes, and functions of one embodiment are shown in Table 1 below: TABLE 1 Various signals from Table 1 are shown in FIG. 11.
- the "type” field represents the type of signal, such as an external input (ext I), external input/output (ext IO), internal output (int O), and internal input (hit I).
- the "size” field represents the bit width of the signal.
- the internal registers 1106 are mapped to a specific location or "window" in the MMC card 1108 address space.
- the base address of the internal register window can be programmed. When the system is powered up, only the base address configuration register is visible at the fixed location which is used to write a new base address for the internal register that is suitable for the system.
- the bridge 1100 replaces read data from the MMC card 1108 with internal register 1106 read data.
- the bridge 1100 includes the same state machine functionality that is implemented within MMC card 1108 to comply with the MMC protocol specification. Most of the time the DISCONNECT_CMD signal is inactive and the MMC host and the MMC Card are connected, the bridge will remain hidden from the MMC bus.
- the MMC bridge monitors commands and responses seen on the MMC bus in order to follow the state changes of the MMC card.
- the bridge will disconnect card and host from each other. If now a response related to that command is detected coming from the card behind the bridge (MMC_B_CMD), the bridge will know that that address belongs to a card behind the bridge or the bridge itself. If the response is detected from the host side of the bus (MMC_A_CMD), the address will not be used by the bridge. After a response has been received, the host and card are connected to each other again.
- the bridge will set the MMC_CMD signal only when the host and card are disconnected or when it is responding to the FAST IO or SET IRQ (interrupt mode) command.
- FIG. 12 One embodiment of an MMC data interface implementation is illustrated in FIG. 12.
- the MMC bridge 1200 includes an internal tri-state condition. When internal register data is to be sent, the buffer 1202 is enabled (EN), the DISCONNECT ED signal disconnects the MMC_B_DAT signal from the MMC card, and the signal(s) to be output (OUT) is sent to the host via the MMC_A_DAT signal. In the illustrated embodiment, the DISCONNECT_DAT signal is thus active when data is read from the internal registers.
- the DISCONNECT_DAT signal is inactive when data is read from or written to the MMC card via the MMC_B_DAT signal.
- This implementation reduces functional complexity inside the bridge 1200 and allows the MMC card to implement the appropriate response protocol for tl e data signal.
- a number of MMC commands are supported by the MMC bridge. These commands are handled by the MMC bridge and by the MMC card. Table 2 below illustrates representative commands that may be actively supported by the MMC bridge. Other standard MMC commands may be passively supported by the MMC bridge by allowing the MMC card to handle them transparently.
- each standard MMC card includes a set of information registers as previously described, which include the CID, RCA, DSR, CSD, and OCR registers.
- certain standard MMC registers are implemented within the MMC bridge. Table 3 illustrates which MMC registers are implemented in one embodiment of the bridge configuration, and how they are implemented. TABLE 3
- FIG. 13 illustrates an example of the MMC card address space 1300, ranging from address OOOOOOOOh to FFFFFFFFh for purposes of example.
- Internal bridge registers 1302 are mapped to a specific location (i.e., window) on the MMC card address space 1300.
- the bridge register address space 1302 includes bridge control/status registers in the first eight bytes of bridge register address space 1302, and includes application registers in the remaining bytes.
- Table 4 illustrates an example of bridge control/status registers used in one embodiment of the invention:
- control/status register includes read (r), write (w), and read/write (rw).
- the MMC_BRIDGE_BAR_X registers represent the MMC bridge base address for the internal registers.
- the MMC_STATUS_ 1 and MMC_STATUS_2 registers provide any desired status, such as whether or not the programmable base address has been configured, whether CRC or programmable base address configuration errors have been detected, etc.
- Another example of a status field is the bridge state (e.g., bits 3:0 of MMC_STATUS_1), which can provide status such as whether the bridge state is idle, ready, standby, read, write, interrupt request, unknown state, etc.
- the MMC_STATUS_1 byte is cleared prior to configuration (described more fully below), and then the configuration process is performed. Bits 4:0 are then checked to determine if the programmable base address has been configured. Finally, the SENSOR_ID byte provides an identification number of the function connected to the bridge. As previously indicated, the bridge registeriaddress space 1302 includes application registers in remaining bytes. Table 5 illustrates an example of bridge application registers used in one embodiment of the invention:
- registers provide application-specific sensor registers depending on the particular sensor(s) application.
- the application-specific register address space begins at address 08h and ends at an address specified for each application.
- Registers may be written using commands such as those identified in Table 2.
- the cmd24_write_block command may be used to write a block of data.
- tlie mechanisms are described in terms of the MMC specification to illustrate one manner of making the MMC card with the bridge implementation of the present invention compatible with the MMC specification. However, these principles may be analogously applied to other interface arrangements. The above sets the stage for a memory mapped access mechanism to access the sensor card functionality and information.
- a set of addresses for the bridge registers 1302 is reserved in the MMC memory address space 1300.
- the relative card address (RCA) may be set wit the cmd03_set_relative_addr command shown in Table 2.
- the bridge detects the relative card address to be used by the card behind the bridge and by the bridge itself by detecting which card responds to the cmd03_set_relative_addr command. In one embodiment, if the card responding to that command is located behind the bridge, then the bridge will use the same address (RCA).
- a fixed bridge base address 1304 has a preset default value after reset in one embodiment of the invention, and is used for setting the programmed bridge base address 1306.
- the fixed bridge base address 1304 is selected such that it does not introduce any conflicts with the file system used on the MMC memory. This can be accomplished in various manners. For example, in MMC memory, the most widely used file system is the File Allocation Table (FAT) system.
- the FAT file system provides for the possibility of defining some reserved sectors in the memory, which will be completely hidden for the file system.
- hidden sectors in the FAT system.
- the MMC card will be formatted in a conventional manner, but with at least one hidden sector. This sector will be then the set of addresses giving access to the sensor module.
- Another possibility is to use a special "system” file at a special location on the memory, such as a file located in the last few sectors of the memory. This file would be recognized as a "system” file by the operating system, and consequently its position would not be alterable by the file system.
- hidden sectors or a system file the situation for the bridge is the same - it will have to respond to a set of given addresses when accesses have to be directed to the sensor module.
- MMC memories come in various sizes, there is no practical way to have a fixed sector (or a set of fixed sectors) for every memory size, and a mechanism should be defined that will program the bridge with the correct set of addresses used to access it.
- the structure of the file system will help.
- four partitions are defined, where some operating systems use only the first two partitions. The structure in the file system may then be used, which defines the two unused partitions. But a mechanism that is not dependent on the use of two or four partitions by the operating system is still needed. This can be solved as follows. Each partition is defined by a structure, which fits in one sector. The two last bytes of this sector are always 0x55h and OxAAh.
- the last two bytes of the two unused partitions may then be used to specify to the bridge the 32-bit linear base address of the sensor module. After overwriting these bytes in this manner, the software used to • configure the bridge is written back to tlie correct value. To avoid any accidental configuration of this base address, a specific procedure may be followed for the configuration. For example, the low 16 bits of the base address is written at the last two bytes of the sector where the structure defining the third partition is located, referred to herein as LOW_ADDR_BASE. Then, tlie previous value, which is 0x55h, OxAAh is written back to that location.
- the high 16 bits of the base address is then written to the last two bytes of the sector where the structure defining the fourth partition is located, referred to herein as HIGH_ADDR_BASE. Then the previous value of 0x55, OxAA is written back to that location.
- Another manner of selecting the fixed bridge base address 1304 such that it does not introduce any conflicts with the file system used on the MMC memory is using application (ACMD) commands. More particularly, this method uses some optional commands of the MMC specification, however only MMC hosts implementing such commands would be able to access the sensor module using this method. Using this method, some application-specific commands are sent to the bridge.
- the MMC memory When one of these commands is sent by the host, the MMC memory will receive this command as well, so care should be taken to avoid any potential conflicts where the memory uses the same ACMDs.
- Another representative manner of selecting the fixed bridge base address 1304 such that it does not introduce any conflicts with the file system used on the MMC memory is using a Fast I/O command. As in the case of using ACMDs, this method uses some optional commands of the MMC specification, and only MMC hosts implementing such commands would be able to access the sensor module using such a method. MMC memories do not use the Fast I/O command, so there is no risk of conflicts.
- this command provides the possibility to read and write to a set of 128 registers, where all or part of these registers can be used to access the sensor module.
- the fixed bridge base address 1304 has a preset default value after reset, and is used for setting the programmed bridge base address 1306.
- the blocklength is set to four or larger with the cmdl6_set_blocklen command shown in Table 2.
- the cmd24_write_block command may be used to write this register, shown as addresses OOh through 03h in Table 4.
- the programmed bridge base address 1306 represents the start address of the memory address space 1300 that is reserved for the sensor interface read and write registers.
- the length of this memory window 1302 is 256 bytes, although any desired length and/or width may be utilized.
- This sensor interface window 1302 becomes visible once the programmed bridge base address 1306 has been set.
- the base address register (addresses OOh through 03h in Table 4) is set as shown in the flow diagram of FIG. 14.
- the blocklength is set to four, as shown at operation 1400.
- the first eight bytes at the programmable address window are cleared 1402, e.g., written to zeroes. These first eight bytes represent the MMC_BRTDGE_BAR_0 previously shown in Table 4. This is performed to later detect whether the bridge is present. Then, four bytes are read 1404 from the fixed bridge base address, and the data is stored.
- This data is read from the MMC card rather than the bridge itself, since the bridge does not respond to read accesses from the fixed bridge base address.
- the programmed base address register is configured 1406 to any value found suitable from the system point of view.
- the value 55h AAh XXh YYh is then written 1408 to the fixed base address, where XXh is the third byte read at operation 1404 and YYh is the fourth byte read at operation 1404.
- Writing 55h and AAh at this point activates the programmable base address and deactivates the fixed base address.
- the four bytes that were stored at operation 1404 are written 1410 back to the fixed bridge base address.
- This data will be written to the MMC card and will not change the programmed base address inside the bridge, since the bridge has been configured at operation 1406.
- configuration of the programmable bridge base address is allowed only once after reset, and the rest of the write operations to the fixed bridge base address will only change the data located in the MMC card. This operation is only needed in addition to operation 1408 if the first two bytes at the fixed base address are different from 55h AAh.
- the MMC_STATUS_1 register (see Table 4) is read 1412 from the programmable base address window. If, as determined at decision operation 1414, tlie least significant bits (LSB) does not read 10100, the configuration is unsuccessful as shown at operation 1416.
- LSB tlie least significant bits
- a bridge as described above further provides for the possibility of the sensor module to access the memory of the MMC card.
- This is referred to herein as multimastering, since both the MMC host and the sensor module can operate as a master using a bridge in accordance with the present invention.
- the bridge is more complex, as it takes into account the possible simultaneous access from the sensor module and the MMC host to the memory device.
- tl e MMC card is seen as a standard MMC card, as the multimaster nature provided by adding the bridge to the MMC card will be completely transparent to the MMC host.
- the MMC card is in the mobile terminal, so both the MMC host and the sensor module are active. In this case, both could attempt to access the memory at the same time.
- the bridge can handle this situation without the need for additional software. More particularly, the bridge can indicate to the MMC host that the bus is busy but will be released soon.
- the bridge can indicate to the MMC host that the bus is busy but will be released soon.
- the status code is a 32-bit word with two bits reserved for application-specific commands. One of these bits may thus be used as a busy state. However, this will lead to a small modification in the MMC host implementation in the mobile terminal.
- the mobile terminal takes this busy bit only for responses coming from a MMC card with a MMC bridge, and ignore this busy bit for a "normal" MMC card with no MMC bridge.
- the MMC host will buffer and delay any access requested by the MMC host until the bus is free again.
- some additional software may be used. This software will simply freeze the MMC host, freeing the bus for a given amount of time. This software will send a command to the sensor module to grant it access to the memory card.
- the software in the host e.g., mobile terminal
- the software in the host will release the MMC host to access the bus again.
- there may be no need to change the MMC host implementation in the mobile terminal but at least a small amount of additional software is utilized.
- This software will simply coordinate the access to the MMC bus, and give the rights to the sensor module to access the bus. Meanwhile, this software will prevent the MMC host from issuing any requests on the MMC bus.
- the MMC card is not in the mobile terminal, but nonetheless is powered up in any manner such as by a battery in the stand-alone configuration. In this manner, only the sensor module has access to the MMC memory, since the MMC host is not present on the bus at all.
- MMC card is installed in a mobile terminal or simply powered up by some other device without a MMC host. This can be done, for example, by using device identifications or the like.
- the sensor device can access the MMC memory using MMC mode, SPI mode, or other analogous mode.
- the host-detachable and stand-alone sensor systems in accordance with the present invention may be used for a variety of purposes. A few representative examples are described herein, although it will be apparent to those skilled in the art from the description provided herein that other uses are equally applicable in accordance with the present invention.

- the media phone and/or the stand-alone device may include contact areas on the surface, such as a "functional cover,” to enable the user to measure and store blood pressure, fat percentage and the like, to see the positive effect of the training program by comparing to previous data.
