摘要
为提高国产加固计算机的计算处理能力,提出基于龙芯3A1500的计算加速模块设计方法,介绍了模块设计思路;硬件方面采用国产龙芯3A1500处理器及DDR3内存,设计了3A1500+2FPGA的硬件组成模式,并介绍了电源及复位电路设计方法;软件方面搭配国产中标麒麟操作系统,设计了与模块匹配的计算加速软件。最后进行性能测试,与X86酷睿L2400进行了性能对比。结果表明,该设计可大幅提高国产龙芯计算机的计算性能,平均计算加速比达到5以上,验证了设计方法的有效性,对国产加固计算机在高性能计算方向的应用具有指导性意义。
To improve the computing capacity of domestic rugged computers, the paper presents a design method of computing acceleration module based on Loongson 3A1500, and introduces the modular design ideas. On the hardware side, using domestic Loongson 3A1500 processor and DDR3 memory, the paper designes 3A1500 ＋ 2FPGA hardware components mode, and introduces the design of the power and reset circuit. On the software side, the module with domestic Neo Kylin operating system and software is designed to calculate the acceleration. Finally, by performance testing, compared with X86 Core L2400 processor, results show that the design can significantly improve the performance of domestic Loongson computer calculation, average calculation speedup reach 5 or more, which indicates the effectiveness of the design method, strengthening of domestic computer has provided guidance in the application of high performance computing sense direction.
