Abstract: FFT算法在计算机科学中具有广泛的应用,自适应FFT软件包以其良好的可移植性而备受研究人员和用户的青睐,龙芯3A是中科院计算所自主研发的四核CPU,采用RISC架构,兼容MIPS指令。主要对FFTW,UHFFT,SPIRAL这3类FFT自适应软件包进行研究。首先从搜索框架和代码产生器两方面总结了FFTW和UHFFT的异同,接着阐述了SPIRAL自动产生优化代码的三层架构实现原理,之后在国产CPU龙芯3A上对这3个软件包进行了性能测试,并结合龙芯的体系结构特点对结果作了分析对比。在最后总结了目前自适应FFT软件包的一般方法,为下一步开发自适应FFT软件包提供了思路。
English Abstract: FFT algorithm has a wide range of applications in computer science. Adaptive FFT software package with itsexcellent portability has been interested by many researchers and users. Loongson 3Ais developed by institute of com-puting technology, Chinese academy of sciences. It is a quad-core CPU and compatible with MIPS instructions usingRISC architecture. The article focused on three types of FFT adaptive libraries which are FFTW, UHFFT and SPI-RAL. Firstly, we compared the difference between FFTW and UHFFT from two aspects of search framework and codegenerator. Then we elaborated SPIRALs three layers schema which is used to produce optimized code automatically. Furthermore, we evaluated these libraries on the Loonson 3Aplatform and analyzed the results. Finally, we concludedthe general method of current FFT adaptive software packages and provided a guideline for further development of a-daptive FFT software package.
