摘　　要：测试国产高性能处理器,充分掌握国产处理器性能,对发挥国产CPU在我国重要工控领域的核心作用具有极其重要的作用.本文依托"核高基"国家科技重大专项,针对当前国产CPU软件库支持欠缺,各类基准测试集无法对国产处理器实现更为精准的性能评估的问题,提出一种基于收敛策略的国产CPU性能测试模型,设计起始运算规模评估模块,并采用三种模块综合评估处理器浮点运算性能,提高测试指标的准确性,运用模型良好的可移植性与测试方法的收敛性,在不同指令集架构的国产处理器下,实现CPU浮点运算、整数运算等多种性能的综合评估.本文选取龙芯2H1000和北大众志PKUnity-3-HD65分别进行模型验证,实验结果表明,该模型在评估国产CPU性能方面具备全面性与高效性,尤其在浮点性能评估方面优势明显,测试结果能够客观反映两款处理器性能,确保了嵌入式处理器在项目应用中的可预测性,对于数控及工控装置国产化具有重要意义.Testing domestic high-performance processors and fully understanding the performance of domestic processors,plays an extremely important role in exerting the core role of domestic CPU in the important industrial control field in China.Domestic CPU software library support is lacking,and various benchmark test sets can not achieve more accurate performance evaluation of domestic processors.This paper relies on the"core electronic devices,high-end generic chips and basic software"national science and technology major project,and proposes a domestic CPU performance test model based on convergence strategy.This model design the evaluation module of initial operation scale,and uses three modules to comprehensively evaluate the performance of the processor floating-point operation to improve the accuracy of the test indicators.Using the good portability of the model and the convergence of the test method,This model implements the comprehensive evaluation of various functions such as floating-point arithmetic and integer arithmetic in the two domestic processor platforms.This paper selects the Loongson 2 H1000 and MPRC PKUnity-3-HD65 for model verification.The results showthat the model evaluates performance more comprehensively,especially in the evaluation of floating point performance.Experimental results can objectively reflect the performance of the two processors.This model ensures the predictability of embedded processors in project applications.This work is of great significance for the localization of CNC and industrial control devices.
