摘　　要：比较和分析了LEON2,OpenRISC1200,NiosII等3种开放性RISC处理器IP核的结构特点,然后分别以三种处理器为核心在FPGA平台上构建了一个评测系统,采用Dhrystone2.1基准测试程序评测了它们的性能。最后在0.18μm的CMOS工艺下进行了综合,给出了它们在ASIC平台下面积和频率的比较。The architectures of three RISC processor IP cores, LEON2, OpenRISC1200 and NiosⅡ, are presented. The test systems, based on the three processor cores respectively, are designed and implemented on FPGA to evaluate their performances using Dhrystone2.1 benchmark. Besides, the paper also presents the comparison of area and frequency on ASIC, synthesized using 0. 18 μm CMOS library.
