摘　　要：本课题是基于VXI总线的高速数据测试模块设计的一部分。测试数据在VXI总线中的传输速度是该测试模块性能的重要指标。为了在VXI总线的模块之间进行大块数据传送,VXI总线规定了实现数据块传输的高速数据通道(FDC)协议。本文讲述了如何在VXI总线模块之间实现大量数据快速传输,包括原理介绍及硬件电路设计。设计充分利用高性能FPGA中FIFO IP core的优点,保证数据快速,稳定的传送。文章对设计过程中出现的问题进行讨论并提出解决方案。This task is a part of design of High Speed Data Testing Module base on VXI bus. The transfer speed is an important guideline for the performance of the testing module. To transmit a large block data between two VXI modules or between commanders and servants, VXI bus defines the protocol of Fast Data Channel to reach this purpose. This paper describes the implement of transferring a great deal of data between VXI modules, including the introduction of principle and the design of hard circuit. The design uses the advantage of FIFO IP core in a high-powered FPGA, guaranteed the fast, stable transferring. The paper also discussed the problems appearcd during the nrocess of design, raises the solve method.
