光纤通信在多核 DSP 信息处理系统中的设计与实现

摘要

设计实现了多核 DSP 系统间的高速光纤通信。采用光电转换模块与8核 DSP TMS320C6678的 SRIO 接口相连的方式，在保证高性能数据处理能力的前提下，完成高速多核DSP 系统间的光纤通信功能。最后对系统进行了测试验证，测试结果表明该系统具有高速、可靠、稳定等特点，具有很好的使用价值。%Fiber optic communication between multicore DSP systems is designed.On the condition of high data processing performance of the system, fiber optic communication is implemented by connect-ing photoelectric switch module to SRIO interface of TMS320C6678 DSP.After verification, the system has been proved to provide high-speed transmission, reliability and fault-tolerance capability, which can meet the increasing requirement of various information transmission.
