摘要
介绍了一种基于SOPC思想的VXI总线数据采集模块的设计方法;该方法用Nios II软核处理器实现了模块化数据采集模块的本地控制器,并将VXI总线接口逻辑和的本地控制器集成在一块Cyclone II芯片内;文章还讨论了数据采集模块驱动程序的开发,制作了虚拟仪器软面板;该模块已成功应用到某型悬挂系统的仿真试验中;利用本文提出的这种设计方法来开发VXI总线数据采集模块,能以单芯片取代以往的多芯片设计方案,大大简化电路板设计,增强电路功能的灵活性和系统的可靠性。
This paper focuses on the design of a VXlBus DAQ modular instrument based on SOPC. We customize an appropriate Nios Ⅱ soft core processor system meeting our needs with the SOPC Builder software, and then we compile the processor system together with the VXI bus interfacing logic RTL model in the Quartos Ⅱ design software, and download the result into a Cyclone Ⅱ FPGA chip. The traditional multi-chip design of "DPRAM+CPLD+MCU" could be replaced with our new SOPC single chip design, The SOPC can help to simplify the design of the PCB board, and what's more, it provides more flexibility and reliability in function, these are the advantages that SOPC de- sign technology brings to us.
