The Implementation and Optimization of FFT Calculation Based on the MT-3000 Chip
摘要
Based on the accelerator chip MT-3000, the FFT algorithm in SAR imaging has been implemented and optimized. The optimization includes vectorization and MPI, DMA transmission and dual buffer transmission, and linear assembly. The experimental results show that on the platform, the performance increased by more than 99.2% after the FFT function was optimized.
