Abstract
In embedded system, performance and flexibility are two of the most important concerns. To solve the problem of the flexibility of GPP (General Purpose Processor) and the performance of ASIC (Application Specific Integrated Circuit), an ARM based RISP(Reconfigurable Instruction Set Processor) architecture is proposed in this paper which adopts partial reconfiguration and coprocessor mechanism to realize the dynamic online reconfiguration of the processor instruction. A prototype system of the architecture is implemented on Xilinx KC705 FPGA and reconfigurable resource management software is designed and developed for the prototype system. DES encryption/decryption algorithms are tested with prototype, and the test results show that the architecture has the both flexibility of GPP and the performance of ASIC, so it has a wide application prospect.
