摘要
本文以高端DSP TMS320C6455为例,介绍了高速SRIO（Serial Rapid IO）接口协议及应用,设计了DSP FPGA高速处理板之间SRIO通信。基于TMS320C6455的SRIO系统,可进行共享式或分布式处理,可以更好地解决＂强大计算能力＂和＂快速数据传输＂两个挑战。实际测量表明,DSP之间的读写操作可稳定工作于每通道3.125Gb/s的速率。
Taking DSP TMS320C6455 as an example,this paper introduces the interface protocol and application of high-speed SRIO（ Serial Rapid IO）,and designs the SRIO communication between DSP FPGA high speed processing boards. The SRIO system Based on TMS320C6455 can perfectly solve the problems of powerful computing and fast data transfer through shared or distributed processing. The test result shows the rate of reading and writing can be up to 3. 125 Gb / s per channel.
