基于PMC标准的四路通用DA板设计实现

本文介绍了一种基于PMC背板标准的四通道通用DA板的设计,采用了Xilinx公司的Spartan3和PLX公司的PCI9656芯片。基于PMC背板标准的设计,使得板卡的应用更加灵活,既可以单独使用,也可以作为母板的一个功能扩展。FPGA增强了DA板对数据进行回放的灵活性,而PCI9656提供了64bit/66M的PCI接口,可以用来进行高速数据交换。通过DA板,可实现对处理后数据的四路模拟输出。

Four Channel Universal DA Board Based on PMC Standard

This article introduces the design of a four channel universal DA board, which is based on PMC standard, apply the Spar-tan3 of Xilinx and PCI9656 of PLX. PMC standard makes the application of DA board more flexible. You can either use it indepen-dently or as an extended part of its motherboard. The use of FPGA enhances flexibility of data processing and output strategy, and PCI9656 provides an interface to PCI bus in 64bit/66M mode, which can be used to implement high speed data exchange. The four channel universal DA board, as is called, output four channel of the processed data to the DA chip to display.
