摘要
首先介绍了TI KeyStone架构多核DSP TMS320C6678EVM板上三种高速串行接口Hyperlink、PCIe和SRIO的传输原理;然后分别对其传输带宽进行了实测,并对影响带宽的因素进行了分析;最后将背板上三种高速串行接口的传输性能进行对比,为研究多核DSP高性能计算提供一定的参考。
Firstly,the paper introduces the principle of three high-speed serial interfaces including Hyperlink, PCIe and SRIO on DSP TMS320C6678 EVM board which adopts TI KeyStone architecture. Then, the actual transmission bandwidth is measured, and the factors affect the bandwidth are analyzed. Finally, the transmission performance of the three interfaces is compared. The research has some reference value for high performance computing on multi-core DSP.
