摘要
数字信号处理器 (DSPs)由于具有高性能和灵活可编程的优点而得到广泛的应用 ,特别是在一些实时的信号处理系统中。如何利用DSPs实现高速采集过程中的实时处理 ,对大型设备的状态监测具有十分重要的意义。本文采用以DPSs为核心的多线程编程 ,实现了VXI模块高速采集、数据的实时分析、数据搬迁的实时处理。本文重点讨论了各个线程之间的载荷分配和时间分配 ,以确保系统的实时性。
Digital signal processor has been widely used for its high performance and flexible programming ability, especially in some real-time signal processing system. How to realize the real-time processing using DSPs during high speed acquisition is very important to the monitoring system of big equipment. The article adopts the multi-thread programming based on DSPs to realize the real-time processing of high speed acquisition, data analysis and data storage. Load distribution and time distribution among many threads are discussed emphatically to ensure the real-time processing of the whole system.
