摘要
描述了一种改进型可重构处理器——GRCC(General Reconfigurable Coprocessor).该处理器能够使用一般通用RISC处理器的协处理器接口,通过与通用处理器的协处理器指令通信,达到辅助主处理器进行大规模密集计算的目的.着重介绍了DCT算法在GRCC中的映射与实现,仿真结果显示,GRCC能达到6倍以上于通用处理器的性能,并在实现复杂度、运行效率与通用性中达到了一个权衡.
This paper describes an improvement for reconfigurable processor. That is the reconfigurable processor communicates with the main processor through the coprocessor interface. The paper introduces the architecture of GRCC, especially DCT arithmetic implementation. The simulation results show that GRCC can achieve six times or much higher performance than general processor, and make a balance among complexity, performance and compatibility.
