【Abstract】 An algorithm of module-based partial reconfiguration on Xilinx and its application in system on programmable chip (SOPC) was introduced. On the hardware and software platform of Xilinx,PowerPC embedded in the XC2VP40 dynamically reconfigures DCT IP modular and IDCT IP modular by internal configuration access port (ICAP). DCT IP modular and IDCT IP modular could be connected with on-chip peripheral bus (OPB). So it realizes high-speed time division multiplex on FPGA hard resources,and reduces power dissipation. At the same time,it improves the usage of FPGA hardware resources.更多还原
