Abstract: In order to improve the performance of domestic computing system, this paper designs a reconfigurable computing system based on domestic CPU. The system consists of host unit based on domestic CPU and FPGA reconfigurable accelerator unit. The CPU acting as the host unit is responsible for logical judgement and task scheduling, while the FPGA is responsible for accelerating the computation task. In order to shorten the FPGA development cycle, the OpenCL framework standard is adopted. To test the peroformance of this system, the AES encryptions with varied length plaintext are tested, compared with the results of CPU serial processing. The system can acquire more than 120 times speedup compared to single FT-1500A CPU core. Experimental results demonstrate that the proposed reconfigurable computing system can improve the computing performance of domestic platform significantly.
