Nowadays, the ability of dynamic reconfigurable in FPGA architecture has gain its importance while switching on hardware modules. But for recent researches on reconfigurable architecture, most of them aim at one specific version. It’s inconvenient by adding additional hardware circuits to apply on all the versions. Therefore, we propose an adaptive hardware context-switching approach for reconfigurable systems. Accompany with the general bit saving format, it suits all types of Xilinx Virtex-2, Virtex-4 and Virtex-5. Which can reduces the saving number of saved frame address and bit-index. Experimental results shown that it reduces 60.39% in memory space and 54.47% in instruction space, by using proposed the adaptive hardware context switching method.
