摘要
为满足可重配置系统的灵活性要求,介绍了一种"ARM处理器+FPGA"结构的重构控制器的设计,提出由ARM微处理器通过模拟JTAG接口的FPGA在系统配置目标可编程器件的方法。给出系统设计的硬件结构,并详细介绍了JTAG在系统配置FPGA的时序要求,以及在此结构中如何利用IEEE JTAG 1149.1边界扫描测试技术和描述JTAG总线标准的XSVF格式配置文件来实现对目标可编程器件进行在系统配置。
The design of reconfigurable controller based on ARM and FPGA is introduced. The method of FPGA configuration with JTAG mode using ARM processor which added the higher flexibility of the reconfigurable system. System structure and function are discussed, the timing using IEEE JTAG 1149. 1 mode and XSVF form configuration files to configurate FPC-A on the system.
