Parallel Radix-2×K FFT Architecture with Conflict-Free Parallel Memory Accessing

Parallel Radix-2×K FFT processing architecture,which can achieve conflict-free parallel memory access,are proposed.According to the conflict-free memory access algorithm,K2-radix butterfly can realize parallel accessing 2 K operands,and the processing speed of FFT was improved Ktimes.Compare with other parallel FFT architecture,the parallel address produce module of the innovative architecture is uniform,so the architecture has good scalability.
