针对高性能处理器龙芯2F的逻辑验证和性能测试,本文设计和实现了一套硬件验证平台环境,既能验证处理器流片前的逻辑功能,也能测试处理器流片后的性能指标。实验结果表明,本文设计的硬件验证平台能够有效验证龙芯2F处理器的各项功能和性能指标。

High performance microprocessor verification and evaluation has become a critical issue in today＇s microprocessor test. In traditional method, the FPGA verification is the first step to verify the logic function, and then real CPUs chip are assembled on the motherboard to test the performance. This method need to spend lots of time in designing two platforms and achieving verification and evaluation process. In this paper, we propose a hardware verification platform to solve the above problem in verifying and evaluating the Loongson2F processor. We can verify the logic function before CPU chip tapeout, and can also evaluate the CPU performance after tapeout.
