Design of Fuze Digital Signal Processing System Based on DSP and FPGA

摘要

In order to increase survey precision and antijamming ability of radio fuze, realize the best matching of fuze with warhead finally, and achieve the best kill and wound effect, the resources and the characteristics of FPGA and DSP chip were considered and fused fully, this article proposed one kind of fuze signal processing system based on soft FIFO interconnection structure of FPGA internal and high performance floating point DSP--TMS320C31 of TI Corporation constitution. First the work principle, the hardware composition and the software architecture of radio fuze digital signal processing system were introduced, then the design circuit of the fuze signal processing system by using DSP+FPGA technology was elaborated. The experiment indicated that this DSP system has the characteristics of highly effective, simple and reliable.
