Description

Advanced Fiber Bus System

Technical field to which the present invention belongs

The invention relates to a physical structure of an optical fiber bus, and belongs to the field of computers and communication.

Prior art prior to the present invention

The bus systems currently used in computer systems all use wires as signal transmission media, and signals are carried by electric fields or currents. The more common bus systems are ISA, PCI, AGP, SPARC, etc., their bus frequencies are below 500 MHz, and we know that the internal frequency of general-purpose CPUs has now reached more than gigahertz (GHz) and will approach in a few years 10GHz. 'At present, the internal frequency of a general-purpose CPU is several times the frequency of the external bus.

At present, many mature optical fiber transmission technologies have been used in the network and communication fields, such as Gigabit Ethernet, and the transmission frequency can reach lGHz. As for long-distance transmission technology, the mature technology is 2.5G DWDM. At present, it has been reported that 40Gbits / S optical fiber communication products have come out. We know that fiber optic communication technology is still not used in the field of computer bus.

The shortcomings of a bus system using a wire as a transmission medium are: 1) The high-frequency characteristics are not good. When the bus frequency reaches hundreds of megahertz, when a large number of modules are connected to the bus system, a large area of circuit boards is required for wiring. However, the line loss and the crosstalk between the lines make signal transmission almost impossible. 2) All current bus systems only specify logical standards and physical standards of the interface. In the implementation of bus standards, people spend a lot of manpower, material resources and time on new wiring design and circuit board manufacturing every month. . At any time, a large number of system motherboards are eliminated. When a computer is upgraded, people often lose one (set) PCI standard computer motherboard for another (set) computer that also has a PCI circuit. This waste is amazing.

Object of the invention

The object of the present invention is to replace a metal wiring circuit board with an optical fiber array as a bus transmission medium, and replace one or more basic advanced optical fiber bus units with a multilayer circuit board to connect electronic components. Technical solution adopted by the present invention

A signal transmission bus system using high-speed optical fiber as a physical transmission carrier is characterized in that it is composed of a plurality of advanced optical fiber bus interfaces, a base of an advanced optical fiber bus interface, a base plate thereof, and various connection members, of which several The base of the advanced optical fiber bus and a base plate constitute a basic advanced optical fiber bus unit, and the bases are interconnected by high-speed optical fiber. The basic advanced optical fiber bus unit is used to connect with various connectors including advanced optical fiber bus interfaces. Connected to provide signal transmission and exchange between various connectors. Multiple connectors and basic advanced fiber optic bus units can be combined to form a multiple advanced fiber optic bus structure with a complex topology.

In this specification, there are three types of connectors mentioned, which are independent data components, interface conversion bridges, and exchange bridges.

The invention is a physical bus design in which an optical fiber array is used instead of a wiring circuit board as a bus transmission medium, and one or more basic advanced optical fiber bus units are used instead of a multilayer circuit board to connect electronic components. It uses a large number of optical fibers to achieve data transmission capabilities far beyond any previous computer bus standard. With the existing dense wavelength division multiplexing (DWDM) technology, a fiber thinner than a wire can have a transmission capacity of 40 Gbits per second, which greatly breaks the upper limit of the transmission frequency of the existing bus system using a wire as a transmission medium. . Using an optical fiber bus can solve the current bottleneck problem of large-scale integrated circuit chips and external wire buses, and give full play to the data processing performance of integrated circuit chips.

The bus system involved in the present invention only involves highly consistent manufacturing processes, technologies and processes, and does not need to continuously carry out complicated, inconsistent circuit board wiring design, manufacturing and testing, which can completely eliminate these previous computer industry manufacturing The required processes can improve the productivity of computer manufacturing, and can save users a lot of costs.

Because the light is used for connection instead of electricity, the present invention can provide the function of plugging and unplugging under power, and also can provide advanced performance with fully customizable control and transmission signaling. These properties are It is difficult to achieve in the system. The bus system of the present invention also provides the performance of multipoint-to-multipoint simultaneous addressing and data reading and writing. This performance is achieved through a special basic advanced optical fiber bus unit BU and a multi-advanced optical fiber bus structure based on this. of.

This embodiment relates to an advanced optical fiber bus unit with four bases. The advanced optical fiber bus units with five bases and more than six bases can be expanded on the basis of four base units, but as the number of bases increases, the backplane optical fiber The wiring can get complicated.

Figure 1 A kind of advanced fiber bus AOFB BU provides 6 dedicated optical fiber data channels, one broadcast data channel (shared data channel) and one control signal channel, which can access up to 4 IDU components. Taking FIG. 1 as an example, a typical personal computer using an advanced fiber-optic bus can insert a CPU 5 with an AOFBI interface on the base 1 of the BU, a mass storage module 6 with an AOFBI interface on the base 2, and a base 3 The graphics processor GPU7 is shown above, and a T-Bridge 8 is inserted into the base 4 so that it becomes a complete high-performance personal PC.

For the industry, the implementation of AOFB must first determine the number of channels. The possible solutions are: 64, 128, or 256 bits. In this way, the five channels (1 shared data channel, 1 shared control signal channel, and 3 dedicated data channels) of the AOFBI in FIG. 1 will provide connections of 320 optical fibers, 640 optical fibers, and 1280 optical fibers, respectively. Corresponding to the AOFBI and the fiber array on the base, that is 18X 18, 26X26, 36X 36. The diameter of the optical fiber holes 15, 15P on the AOFBI and the base can be between 0.1 mm to 0.6 mm. The standards that the industry must negotiate and formulate include: the size of A0FBI and its base; the geometric dimensions of fiber arrays 12, 12P, hole pitch, channel physics- Logical correspondence relationship; geometric division of electrical areas 13, 13P, electrical interface standards, power supply voltage, power standards; Finally, the most important thing is to formulate a control signaling protocol or control channel usage protocol.

In an electrically connected chip-multilayer board circuit system, control is achieved through fixed connection of chip pin leads and fixed matching of signal levels and timing, such as addressing, data read and write control, interrupt requests, etc. We can call this kind of control hard control. In the fiber-optic bus system, there is no fixed connection of chip pin leads, so the concept and method of control is completely different from the chip-multilayer circuit of the electrical connection. In the fiber-optic bus system, control is achieved by signaling and protocols. This is similar to the control concept in the communication field. For example, the control channel can be used to send a character or byte representing the meaning of control to achieve control. This kind of control is called soft control. Compared with soft control, hard control has the characteristics of fast response speed and simple processing circuit. However, although soft control has a slower response speed and requires more complicated circuits and software, soft control can achieve more complex and flexible control and more Good compatibility. When soft control is facing the transmission of large blocks of data, its control speed and efficiency are not lower than hard control. This specification does not discuss the development of these signals, protocols, and methods for implementing control, but only provides the basis for implementing these functions.

The independent data unit IDU is produced by different device manufacturers. First, they connect the internal circuit signal leads to the electro-optical conversion elements, and then direct the optical signals into the AOFBI fiber holes, or from AOFBI. The optical signals are introduced into the photoelectric conversion element array connected to the internal circuit. Finally, after packaging the AOFBI and the photoelectric / electro-optical conversion device array and internal circuits, an IDU is manufactured.

Advanced fiber optic bus systems place high demands on the manufacturing accuracy of AOFBI and its base. The electrical plugs and jacks are not only used to provide electrical connections. They also have an important function, which is to provide alignment guidance to guide the alignment of the optical fiber holes of the AOFBI and AOFBI bases. The internal structure of AOFBI and its base is shown in Figure Ί. The axis is parallel to the center axis of all electrical holes, and the allowable angle error is less than 0.005 radians. Similarly, the center axis of hundreds of thousands of fiber holes 15P in fiber arrays and 21P of fiber buried holes are parallel to the center axis of all electrical plugs. The allowable angle error is less than 0.005 radians. When the non-deformable electrical plug and the electrical jack are fully joined, 21, 15, 15P, and 21P can be aligned, and at the same time, the embedded optical fibers 22, 23, 22P, and 23P are aligned, and the convex lens 19 embedded in the optical fiber hole 15 is aligned. The large-diameter transparent cylinder 18 is aligned with the large-diameter transparent cylinder 18P with a convex lens 19P embedded in the optical fiber hole 15P. Because the optical signals of the micron-level fiber cores 23 and 23P are amplified into the large diameter transparent cylinders 18 and 18P in the fiber hole, even if there is a slight horizontal displacement between the fiber holes 15 and 15P (in the order of 0.1 mm to 0.2 mm) ) Will not affect the transmission of optical signals, at most it will only cause some optical loss. 24 ~ 25 is an ideal optical signal transmission, but due to the alignment errors of 21, 15, 15P, and 21P, the angle between them is not strictly equal to 0, but there is a slight angle. The signal will deviate from the center axis of the lens after being focused by the lens. In order not to defocus the signal too far from the core, the opening position of the core can be placed in front of the lens focus. This can reduce the loss of optical signals caused by the focus deviation of the optical signal. Probability, but at the cost of significant attenuation of the signal. Fortunately, in the advanced fiber-optic bus system, the optical signal is transmitted at a short distance, and it does not exceed 30 cm in the BU, so the optical signal transmission quality will not be worse than the remote communication quality. When the AOFBI and its base are joined, the gap of the interface 17 is required to be uniform and narrow enough.

Due to the reflection of light when passing through different interfaces, there are a total of 4 reflective surfaces in the 24 to 25 optical paths in Figure 7. The presence of the reflective surfaces will increase the attenuation of the transmitted signal and also increase the interference of the received signal (Advanced Fiber Bus Each bit of the channel interface uses a fiber to send and receive at the same time). For this reason, FIG. 8 shows an alternative interface surface structure scheme for reducing two reflecting surfaces. The interface surface of the AOFBI base portion 16 is a spherical surface with a small arc recess. The interface surface portion 16P of the standard advanced optical fiber bus interface AOFBI is a spherical surface with a small arc protrusion. Concave The direction of the surface is opposite to the direction of gravity, and a transparent high-refractive oil 26 is placed at the bottom of the concave surface. In this way, when the two interfaces are facing closer, the air is discharged by the oil surface as the interface faces closer. The interface of the two interfaces Between 17 is filled with evenly distributed oil. The light beam 27 of the optical fiber array on the interface surface can reach the other side of the interface through the oil-immersed interface instead of the air interface. In this process, the reflection of the two reflecting surfaces is greatly eliminated.

The fiber arrays of the AOFBI and AOFBI pedestals in Figure 1 to Figure 4 can be divided into 5 channel interfaces, each channel has 64 or 128 or 256 bits. These five channels can be named shared data broadcast channel B, shared control signal channel C, and dedicated data channels D1, D2, D3. In the BU of FIG. 1 and FIG. 2, one corner of the bottom plate 9 is notched. The AOFBI base near the notch is numbered 1, and then the AOFBI bases are numbered 2, 3, 4 in a clockwise direction. . The bottom plate 9 is a double-layer structure, and the interlayer is a fiber bus distribution layer. The number 10 in the figure is the connecting optical cable bus between the exposed base and the fiber holes of the base. The fiber length between any pair of fiber holes is equal, so that the consistency of the delay in the BU and the signal can be guaranteed Arrivals. The base plate 9 provides electrical connection to the AOFBI base. An optical synchronization signal source for the use of this BU is also provided on the bottom plate 9 with a frequency of 1G, 5G, 10GHz. These synchronization signals will provide synchronization signals for control to the IDU and the bridge through the AOFBI base. Each BU has a serial number that can be read by the IDU and the bridge. This serial number is unique and it plays a key role in remote addressing within the Multi-Advanced Fiber Bus Multi-AOFB. The base number of each AOFBI base is readable, which is necessary to provide addressing.

The AOFBI bases numbered 1, 2, 3, and 4 on the BU in FIG. 2 have a total of 12 interfaces on the D1, D2, and D3 channel interfaces on the fiber array. As shown in FIG. 6, they use 6 dedicated fiber channels. The specific topology relationship is: 1D1-2D1, 1D2-3D2, 1D3-4D3, 2D2- 4D2, 2D3-3D3, 3D1-4D1 _0. Such a structure provides extremely powerful data transmission capabilities. Taking Figure 1 as an example, 5 is CPU, 6 is memory, 7 is graphics processor GPU, 8 is T- In the case of Bridge, the following series of operations may occur in this system: The CPU uses a 1D1 channel to write a data to the address al through the 2D1 interface of the memory, and another process of the CPU reads a data from the a2 address sent from the memory from the 1D1 channel. The GPU reads a data block from the memory a3 address through 3D3. The GPU sends the 3D colored RGB data to the 4D1 interface of T-Bridge through 3D1 and then sends it to the display. T-Bridge passes the data block from the hard disk through 4D2, 2D2 The disk buffer sent to the a4 address of the memory is used for the update operation, and the GPU and the CPU perform a session through 1D2 and 3D2. In current PCs, most of the above operations must be completed one by one by queuing and sharing the bus one by one, but in advanced fiber-optic bus systems, the above series of operations can be performed simultaneously through six independent channels. Of course, the prerequisite is that IDU internally supports multitasking. For example, the IDU memory must be able to read and write data at 4 different addresses at the same time.

The AOFBI pedestals numbered 1, 2, 3, and 4 on the BU in FIG. 2 are connected with the B and C channels on the fiber array through a special coupling fiber structure. For example, the first C (0) of the C channel, and the 4 C (0) on the BU are: 1C (0), 2C (0), 3C (0), 4C (0), which are led out from the fiber hole After exiting the optical fiber buried hole of the AOFBI base, the single optical fiber is divided into two forks respectively, and the optical path is also divided into two forks at the same time. The four C (0) correspond to eight branched optical fibers, and then the eight optical fibers are combined into FIG. 5 The 4 petal-like structures in the middle show that they are reassembled into 4 optical fibers again, and the optical fiber distances of each optical path are strictly equal. Such a special structure can make the optical signal from any C (0) reach the other 3 C (0) at the same time. A plurality of such special coupling fibers are aggregated to form a bus structure of the B and C channels of FIG. 5. The shared data channel must be connected to each other by the connection method as above. Because the optical signal and the electrical signal are different, it is directional and cannot be turned at will like the electrical signal. Every place that needs to turn, split, and merge must be carried out. Careful special handling. This characteristic of the optical signal determines that the physical structure and connection relationship of the optical bus must not be the same as the electrical bus. The purpose of the broadcast channel is that once an IDU communicates After obtaining the broadcast data channel through the control channel protocol, it can put data on the broadcast channel, and these data reach the other 3 interfaces at the same time, without using a dedicated data channel to send the data to the 3 interfaces in 3 times.

Bridges are important components in advanced fiber-optic bus systems. They are responsible for data forwarding and signal conversion. A repeater that provides complete forwarding functions usually has extremely strong data processing capabilities and a sufficiently large data buffer. It needs to establish a bus topology table and place addressing data across BUs on the correct ports. If it is across systems For data exchange, a signal conversion layer is needed to convert the signaling and data of the advanced fiber-optic bus into control and interface signals outside the system. These conversions are performed by a conversion bridge (T-Bridge). Switch Bridge (S-Bridge) is for the advanced fiber bus Multi-AOFB structure. By connecting BU and S-Bridge in different ways, we can get a variety of Multi-AOFB topologies. . Figure 9 shows the Multi-AOFB topology consisting of several common and simple 4-base BUs. There are only two operations across BUs in Multi-AOFB: addressing and data reading and writing. Addressing here refers to the requirements of a specific IDU for the data channel of the IDU and the bridge in another specific location. An IDU can only be accessed through one of its 4 channels. If there are more than 4 components in the Multi-AOFB bus, access failure may occur. Because the 4 channels of the IDU may be occupied by other IDUs and bridges. In this case, the addressing initiator can wait, or request the S-bridge to buffer data and requests, and wait until the target channel is released before sending. A two-port S-bridge needs to query the bus topology table and control data transfer between 6 dedicated data channels and 2 broadcast data channels, and also analyze the signaling from the 2 control channels. The addressing between IDUs in the BU does not need to wait, and the addressing speed is completed within the fastest 2 nanoseconds (fiber delay). The addressing between the BU and the BU is affected by the fiber bus distance and bridge The limit of the response speed is relatively slow, and there may be an address waiting. We call the addressing outside the BU remote addressing, remote addressing via an S-bridge It is called a hop, remote addressing through two S-bridges is called two-hop, remote addressing through three S-bridges is called 3-hop, and so on.

The bus system discussed earlier only considers the case of transmitting one carrier within the optical fiber. In fact, an optical fiber can theoretically transmit hundreds or thousands of carriers in different frequency bands. These carriers can be regarded as multiple transmission channels re-divided in one fiber channel. If the wavelength division technology is used, the number of channels that can be used between the IDU and the bridge and the bridge is not five but more. Especially for the data transmission between the bridge and the bridge, it is most necessary to use the wavelength division multiplexing technology to obtain greater data transmission capabilities. It can be seen that the system transmission capacity of the advanced optical fiber bus system is very huge. The potential of multipoint-to-multipoint transmission can still be explored.

The advanced fiber bus can be widely used in parallel computer systems and neural network computing systems, and it can also be applied to personal computer systems. The current PC-standard personal computer's electrical bus cannot carry CPUs with internal gigabit frequencies in the future. Therefore, it is necessary to transplant the current PC software platform to the system of the advanced optical fiber bus standard. Fully compatible migration is possible, but some technical problems must be solved. First of all, the problem of instruction set compatibility must be solved. For example, the OUT instruction, IN instruction, interrupt mechanism, and DMA mechanism of Intel's x86 series processors are not compatible with advanced fiber optic bus systems. The method to solve this problem is to set a control signal conversion layer under the existing architecture of x86, convert the x86 external control signals into advanced optical fiber bus signals, and convert the advanced optical fiber bus signals about I / O, interrupts, and DMA. The signal is sent to the T bridge, and the relevant layer of the T bridge is used to restore the relevant signals and send them to the corresponding interfaces such as interrupt controllers and various external devices.
