The present invention relates to embedded system, refer in particular to the method and the device of the instruction of executing the task in a kind of embedded system.
Background technology
The device that instructs of executing the task in the embedded system of the prior art generally is divided into PC and senior reduced instruction set computer microprocessor (ARM, Advanced RISC Machine) two parts.In general, PC partly is used for providing the debugging interface to programmer or user, receives the program or the task of outside input, sends to the ARM part after received program or Task Switching are become the discernible code of ARM part; The ARM part is then carried out concrete operation according to the code that PC partly sends, and finishes the program or the task of required execution.Simultaneously, the ARM part also can directly receive the program or the task of outside input, but program of being imported or task are necessary for the discernible form of ARM part.PC part and ARM partly generally can be divided into 3 levels for the processing procedure that being imported of task or program are carried out:
1) uses (App, Application) layer: its function is to receive the task or the program of outside input, it is assignment instructions, and received assignment instructions resolved into one or more concrete functions that relevant chip can realize, the for example combination of the preview of chip (Preview) pattern and sectional drawing (Capture) pattern etc., and the function of the required realization after will decomposing sends to Drive Layer;
2) drive (Driver) layer: the various functions that needs that will be received are realized are decomposed into a series of corresponding concrete operations instructions respectively, and as to certain function calls etc., and the concrete operations after will decomposing are instructed and sent to the base register writable layer.For example, the function of Shi Xianing is if desired: the size that each module under the Capture pattern is set, then above-mentioned Function Decomposition can be corresponding a series of operations of calling the SetCaptureSize function, can be by the difference of SetCaptureSize function being called the function that realizes being provided with the size of each module under the Capture pattern.
3) base register read-write (Baserw) layer: concrete operations instruction that will be received is decomposed into corresponding a series of read-write operations to the base register in the chip and instructs promptly the most basic operation to chip.To be converted into the discernible read-write operation instruction of ARM part by the read-write operation instruction after the decomposition of PC part Baserw layer, and send to the Baserw layer of ARM part; The Baserw layer of ARM part then according to the read-write operation instruction that receives, carries out read-write operation to the base register in the chip.
Fig. 1 is the structural representation of the device of the instruction of executing the task in the embedded system in the prior art.As shown in Figure 1, execute the task in the embedded system in the prior art instruction device comprise PC 101 and ARM 102 two parts.Wherein, PC101 also comprises: application layer module 103, Drive Layer module 104, base register writable layer module 105 and command analysis device (Cmd Protocol) 106; ARM 102 comprises: application layer module 107, Drive Layer module 108 and base register writable layer module 109.
When the device of the instruction of executing the task in the above-mentioned embedded system receives the assignment instructions of outside input, can be with among this assignment instructions input PC101, this assignment instructions is broken down into a series of corresponding read-write operation instructions successively by after application layer module 103, Drive Layer module 104, the base register writable layer module 105; Base register writable layer module 105 will be decomposed good a series of read-write operations instructions and be sent to command analysis device 106 then; Command analysis device 106 becomes the compiling of instruction that receives can be instructed by the read-write operation that ARM discerns, by USB (universal serial bus) (USB, Universal Serial Bus) or UART Universal Asynchronous Receiver Transmitter (UART, Universal Asynchronous Receiver/Transmitter) directly sends to base register writable layer module 109 among the ARM102, base register writable layer module 109 is carried out read-write operation according to the instruction of received read-write operation to the base register of chip, finishes whole task or program.
