摘要
根据处理流程的并行可分性进行任务规划,提出了一种基于共享存储器的高速数据采集处理系统的设计方案.系统采用双数字信号处理器(DSP)流水线体系结构,一个DSP单元负责多路外部总线的信号采集、数据校验与过滤,另一个DSP单元完成数据运算、综合评估,二者并行工作大大提高系统的处理能力,能很好的满足快速实时数据采集和高效任务处理的需要.
According to the parallel division of processing flow to make task layout,this paper gives a design scheme of high-speed data acquisition and processing system based on share-memory.In two DSPs streamline system structure,one is for signal acquisition,data checkout and filter,the other fulfills data computing and complex evaluation.The two DSPs parallel-working enhances system processing ability greatly and satisfies the demand of real-time data acquisition and task processing effectively.
