摘要
本文以高端DSP TMS320C6455为例,介绍了高速SRIO(Serial RapidIO)接口协议及应用,设计了DSP间的SRIO通信,研究了基于SRIO的加载技术,并且分析了基于DSP和FPGA的SRIO网络通用处理平台等。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"两大挑战。实测表明,DSP间,DSP与FPGA间的读写操作均可稳定工作于每通道3.125Gb/s的速率,主DSP可通过SRIO加载从DSP。本文可作为SRIO接口设计及TMS320C6455通用处理平台开发的参考,也可作为今后复杂信息系统设计的参考。
The high-speed SRIO （Serial RapidlO） protocol was introduced and analyzed and its application based on DSP TMS320C6455. It shows the design of SRIO transmission between different DSP and SRIO-based boot mode for DSP, analyzes the SRIO-based processing platform using DSP and FPGA. A TMS320C6455 system based on SRIO can work in shared-mode or distributed-mode, which can solve the two challenges ＇ powerful computing capacity＇ and ＇ data transmission in high-speed＇ best. The test result shows that the read and write operation can stably work at 3. 125Gb/s per channel between different DSP or between DSP and FPGA. The master DSP can load the slave DSP by SRIO. This paper can work as an example design for SRIO interface or TMS320C6455, it also can be the reference to a design of complex information system.
