| 中文摘要: |
| 介绍了基于SRAM LUT结构的FPGA的几种在线配置方式,同时给出了在嵌入式系统中利用ARM7TDMI微处理器产生FPGA配置时序的方法;给出了最小系统应用电路;结合程序,分析如何产生FPGA的配置时序;本方案的实用性在本文得到充分说明. |
| 英文摘要: |
| In-Chip configuration modes and configuration files of FPGA,based on SRAMLUT structure,are presented,and one of them,passive serial configuration method(PS mode) is selected finally in this system.Also,in this embedded system,using ARM7TDMI micro-processor to produce FPGA configuration clock is proven available.A Mini-application system,with codes related,and analyzing how to generate FPGA configuration clock,is given.The result of the paper shows the design could be realized in practice. |
