摘要
华睿1号是我国自主研制的一款4核微处理器,该处理器内部集成了矢量处理部件,扩展了包含快速傅里叶变换(FFT)蝶形运算指令在内的矢量指令集,具有很强的FFT运算和数字脉压处理能力。在嵌入式实时操作系统下的实测表明华睿1号单核处理1 024个单精度浮点复数FFT和数字脉压的运算时间分别为6.12μs和15.36μs,采用多线程FFT并行处理技术后,4核加速比可达3倍以上,满负荷功耗仅10 W,总体性能优于国内外同类处理器,适用于对实时性要求较高的雷达信号处理和电子对抗等领域。
HuaRui-1 is a low-power, high-performance embedded processor developed by NRIET. The 4 cores MPU with Vector Processing Unit （VPU） can be applied to most field which has massive data to be processed. A set of special vector instructions for butterfly operation of FFT is elaborated in this paper. Test result showed that 1 024 point FFT and DPC based on single core of HuaRui-1 can be accomplished in 6.12 μs and 15.36 μs. It can be used for radar signal processing and electronic countermeasure to meet the real-time requirements.
