基于GPU的信号产生及脉冲压缩实现
Signal Generation and Pulse Compression Realization Based on GPU
摘要
Abstract
A signal processing scheme based on CPU+GPU heterogeneous parallel architecture is proposed in this paper.According to radar processing flow,the general computer uses CPU to complete data preparation and device initialization before kernel function starting,and control the task scheduling and load sharing of signal processing,then,the data will be transmitted through the PCI-E bus to the memory of GPU.The specific way of SIMT of GPU is used to achieve thread parallelization,and finally finish the LFM signal generation and pulse compression algorithm.A comparison with the algorithm realized on CPU is made.The experimental results show that the algorithm achieved by CUDA has higher efficiency than CPU.关键词
