摘　　要：从自主研发的角度,介绍了一种基于Nios II软核处理器的高速多路数据采集系统的设计和实现过程,并说明了SOPC系统开发的一般流程以及系统软硬件架构的设计;该系统采用AD522芯片实现了信号放大,采用AD976进行数模转换,采用K6T1008C2C-L进行数据存取,采用USB接口芯片ISP1581与工控机进行通讯,FPGA芯片采用ALTERA公司的EP2C5F256C8;该系统是以PFGA为核心,体现了SOPC系统集成度高、灵活性强的特点,并能缩短产品的开发周期。The design and implementation of high speed multichannel data gathering system based on NIOS II is introduced, and then illuminates the general method of SOPC, design and achievement of system software and hardware architecture. AD522 is integrated to realize magnifying. AD976 is integrated to realize converting. K6T1008C2C--L is integrated to realize storage. USB interface IC ISP1581 is integrated to communicate with industrial computer. EP2C5F256C8 is chosen as FPOA. FPGA is the core of the system, showing high integration, flexibility, expendability of SOPC and reduction of the time of development of product.
