一种多DSP的并行数据处理系统设计及其实现

摘要

To heighten data process performance and apply the advantage of the Multiprocessor System, a Muhi-DSP parallel data processing system based FPGA is depicted in this paper. The connect method between DSP is realized by Link interface, the data transmission is realized by FPGA and the CPCI is used as the data channel between the system and host machine in the system. The programmer load method and data transfer flow is described in detail, and this system has several advantages such as high efficiency of data process and strong calculation ability, etc.%为提高数据处理性能，发挥多处理器并行数据处理性能优势，提出了一种基于FPGA的多DSP并行数据处理系统设计方案。在设计中，DSP之间的通信采用Link口方式实现，利用FPGA实现数据传输，利用CPCI总线作为系统与主机的数据传输通道。详细介绍了系统的程序下载和数据传输流程，该系统具有数据处理效率高，运算能力强等优点。
