基于VXI总线高速数据采集的DSPs多线程实时处理
DSPS MULTI-THREAD REAL-TIME PROCESSING BASED ON VXI HIGH SPEED ACQUISITION
【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。
【Abstract】 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 real-time processing using DSPs during high speed acquisition is very important to 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.
