RapidIO链的设计方案和应用
Design and application of RapidIO chain
摘要
Abstract
SRIO(Serial RapidIO) supports two work modes:Message and DirectIO.The DirectIO mode is simple to operate,but in multi-packets transmission case,DSP CPU must wait until LSU(Load and Save unit) register is free.To solve this problem,the paper presents a new transimission way named RapidIO chain,which uses EDMA(Enhanced Direct Memory Access) channel instead of CPU to configure LSU registers of SRIO.Resuhs of experiment show that RapidlO chain can reduce CPU load effectively.关键词
