本文提出了在uClinux 嵌入式操作系统中应用MCU 实现对FPGA 的一种配置方案。该方案实现了FPGA 配置数据的加密、压缩，减少了配置文件对嵌入式存储资源的占用，并且实现了FPGA 资源的在系统动态配置，本文还介绍了动态配置技术在多编码支持
VOIP 终端上的应用实例。

Abstract: The paper proposes a FPGA dynamic configuration scheme with the management
of uClinux. An architecture of ARM and FPGA based uClinux system is presented which
implements dynamic devices. It describes how FPGA configuration data is encrypted and
compressed to reduce the space requirement of FLASH. It also introduces an application of this technology on VOIP terminal.
Keyword: Embeded System, FPGA, Dynamic Configuration, uClinux, Device Driver, VoIP
