摘要
由于基于SRAM工艺的FPGA器件具有掉电易失性,故在一些工程系统中可采用被动配置的方法,文中以Altera公司的EP4CE6为例,利用单片机采用PS配置方式为FPGA进行上电加载及远程加载,并应用于显示远程控制系统中。实践证明,此方案加载成本低、简单易行、可靠性好、解决了采用SRAM工艺的FPGA器件掉电易失性的问题。
Since it is easy for an FPGA device based on SRAM technology to lose data when it is powered off, in some engineering systems the use of passive configuration is required. This article takes Altera EP4CE6 as an ex-ample, using the microcontroller and adopting the mode of FPGA PS configuration on electrical load and remote load-ed, which is applied to the display in the remote control system. Practice shows that this solution is simple, reliable and low in cost.
