FPGA的AP模式及在可重构仪器中的应用

Application of FPGA Configuration on Reconfigurable Instrumment Based on AP

针对目前在可重构仪器设计采用PS配置方式需增加CPLD或单片机配置电路且配置时序较繁琐的问题,提出一种基于FPGA的AP配置模式可重构仪器设计方案。采用flash和SD卡存储软硬件配置文件,在SOPC Builder中调用ALTREMOTE_UPDATE、PFL和SD卡控制器IP核,实现FPGA的AP配置模式。该模式具有使用方便、集成度高、数据传输可靠、易于远程升级及维护等特点,在基于可重构技术的多功能仪器中得到良好的应用。

In order to solve the problems of PS configuration mode on the design of reconfigurable instrument,which needs adding CPLD or microcontroller configuration circuit and configuring timing is more complicated,a reconfigurable instrument design based on FPGA＇s AP configuration mode is put forward.This paper uses flash and SD card to storage hardware and software configuration files,and calls ALTREMOTE_UPDATE,PFL,and SD card controller IP core in the SOPC Builder to implement AP configuration mode of FPGA.This model is easy to use,highly integrated,reliable data transmission,easy remote upgrade and maintenance,and gets a good application on reconfigurable technology-based multi-functional instrument.
