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ARM 7TDM I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。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 ARMTTDMI 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.
