摘　　要：可重构技术既具有硬件任务的高效性又具有软件任务的灵活性,近年已经成为研究热点,并越来越广泛的应用到实际系统之中.应用在化工、电力、冶金等行业的大型监控系统中的多通道数据采集系统具有高可靠性、强实时性和高并行性特点,典型的多通道数据采集系统普遍采用ASIC集成电路设计,可配置性、灵活性和扩展性差,本文提出一种将局部动态可重构技术应用到多通道数据采集系统的设计方案,提高了系统的可配置性和应用范围,并且系统具有更高的实时性和并行性.The reconfigurable technology not only with the high computing capacity of hardware,but also with the flexibility of software,so it is becoming more and more important in the recent research field,and more and more widely used in the real application field.Multi-channel data acquisition system is the most important part of monitor and control system for mechanical,power plant,and metallurgy industry.The system is typically with the characters of reliability,real time,and parallel demanding.Most of the systems for data acquisition today are designed by ASIC technology and are lacking of reconfigurebility,flexibility and scalability.This paper proposes an innovation approach for data acquisition system by using the reconfigurable technology.The proposed approach has higher parallelism and provides better real-time performance.
