摘要: 基于现场可编程门阵列(FPGA)的可重构系统具有高性能和高灵活性,但随着FPGA规模的不断扩大,配置文件规模相应增加,导致可重构计算时间过长。该文提出一种FPGA配置文件压缩算法VLZW,降低了对片外存储器的容量要求,通过减少每次重构传送的配置数据缩短了系统重构时间。

Abstract: The reconfigurable system based on Field Programmable Gate Array(FPGA) has high performance and flexibility. With the enlarging of FPGA size, the dramatic increase in configuration data size has resulted in a corresponding increase in the time required for reconfiguration. This paper proposes a FPGA configuration compression algorithm——VLZW which can reduce the off-chip memory required for storing FPGA configurations. This algorithm cuts down the reconfiguration time of the system by reducing the transmittal configureation data.

Key words: Field Programmable Gate Array(FPGA), configuration compression, reconfigurable
