Computer hardware platform design method based on DSP (digital signal processor) and FPGA (field programmable gate array)

Abstract

A computer hardware platform design method based on a DSP (digital signal processor) and an FPGA (field programmable gate array) includes the steps: utilizing the DSP and the FPGA as a core to expand a program load module, a data storage module, an analog input module, an analog output module, a switching value input module, a switching value output module, a serial port communication module, a 1553B communication module, a reset circuit and a power circuit, so that an embedded computer hardware platform is built; and acquiring the analog quantity and the switching value, realizing high-capacity program and data storage and a complicated algorithm, realizing communication of the embedded computer hardware platform with peripherals, and controlling the embedded computer hardware platform. By the aid of the method, automatic switching of analog signal input and output is realized, switching value signal input and output are freely expanded, operating efficiency of a processor is greatly improved, systematic resources are saved, development cycle is shortened, and development cost is reduced. Another novel hardware design platform can be completed only by changing codes of the FPGA.
