介绍了一种在PC机上CPU通过总线对现场可编程门阵列 (FPGA)进行配置的方法 使用这种方法对于一个基于计算机总线的使用现场可编程门阵列 (FPGA)的系统设计来说十分方便 ,其中FPGA的功能配置无需加载电缆就可以进行 ,使整个系统的配置、调试能够同步进行 实现这一通过PC机CPU直接对FPGA进行功能配置的关键是在FPGA的功能设计中包含了一个测试电路 ,其输出作为配置成功的一个反馈信号 This paper presents a method of configuring the field programmable gate array (FPGA) by the CPU through a bus on a PC. This method is very convenient for designing a system based on a computer bus using a field programmable gate array (FPGA) Which FPGA configuration without having to load the cable can be carried out so that the entire system configuration and debugging can be synchronized to achieve this through the PC CPU directly to the FPGA configuration function is the key to the functional design of the FPGA includes a test circuit, Its output is used as a feedback signal for configuration success
