摘要
TS201高速通信接口LinkPort传输速率高、抗干扰强,可满足多DSP系统内数据实时快速交互。但由于缺乏握手机制,各DSP系统间LinkPort数据传输不同步,容易产生传输超时错误和乱序现象。在分析LinkPort工作机理的基础上,提出多DSP系统间LinkPort数据同步传输技术,利用通用输入输出信号和中断信号握手来实现多个DSP系统间LinkPort数据同步传输,有效地解决了LinkPort传输不同步造成的超时错误和乱序现象,使收发设备之间可以准确地同步,提高了传输的效率和准确性。
The LinkPort of TS201 can satisfy the high speed and anti-disturb requirements of data exchange between multi DSP.But without shake-handle mechanism,it will occurres errors of timeout and in disorder during data transmission.The article analyzes the mechanism of LinkPort,and proposes the technology of LinkPort Data transmission sychronization on Multi-DSP system,which uses the general-purpose input or output flag pins and the signal of interrupt to make sure data transmission sychronization and preciseness.
