[Abstract]:In the application of aerospace embedded processor, the implementation of general purpose processor or ASIC (ASIC) can not meet the requirements of performance and flexibility at the same time. The ASIP processor (ASIP) balances the high performance of ASIC and the programmable characteristic of general-purpose processor. It is a microprocessor specially designed for a particular application or application in a certain field. This paper focuses on the design and implementation of the special instruction set processor for aerospace embedded application. Firstly, the SPARC architecture is selected as the basis of the implementation of the special instruction set processor. According to the design method of special instruction set processor and the characteristic of FPGA hardware resource, the system structure and instruction set structure of SPARC architecture are simplified and optimized, and a set of special instruction sets is extracted. Secondly, in order to improve the performance of the special instruction set processor, according to the resource characteristics of FPGA, the special instruction set processor adopts a five-stage pipeline structure. Data-oriented techniques and branch-unexecuted strategies are used to solve data risk-taking and control risks in pipeline respectively. Finally, the system simulation and comprehensive verification of the whole ASIP are carried out with the FPGA Vertex-6XC6VLX240T of Xilinx Company as the carrier. At the same time, the bubbling sorting algorithm and the FIR digital filter are implemented on the special instruction set processor. The simulation and verification results show that the designed special instruction set processor can achieve the expected function and timing requirements, and because of the compact circuit structure, it can integrate multiple special instruction set processor cores to realize parallel processing in a single FPGA.
