基于DSP EMIF口及FPGA设计并实现多DSP嵌入式系统

Design and implementation of multi DSP embedded system based on the DSP EMIF port and FPGA

在实时图像处理、雷达信号处理、软件无线电、电子对抗、3G数值仿真计算中,单DSP无法满足实时性和高速运算量要求,往往需要多DSP进行协同处理。本文针对DSP的EMIF接口和FPGA的特点,设计8个DSP通信的嵌入式系统。试验结果表明,所设计的多DSP通信的嵌入式系统,工作性能稳定,数据处理能力强,适用于高端的雷达信号处理、电子对抗、超声图像处理等场合。

In the field of real-time image processing, radar signal processing, software wireless, electronic antagonizing and 3G numerical emulating reckon, the hardware system based on single DSP only is not able to satisfy the requirement of real time and high-speed reckon, therefore the system based on multi DSP cooperating with each other is required. In this article,an embedded system of eight DSPs which communicated according to the EMIF interface and the FPGA character was designed. The results of the experiments show clearly that the performance of this embedded system based on eight DSPs is stabilizing and superior, which owns the ability to be used in the field of radar signal processing, electronic antagonizing, ultrasonic image processing, et al.
