1999-10-26 Parallel 1-D FFT implementation with TMS320C4x DSPs
The purpose of this application note is to investigate efficient partitioning/parallelization schemes for one-dimensional (1D) FFTs on the TMS320C40 parallel processing DSP. This document focuses on complex FFTs; however, the concepts used can be easily applied to real FFTs. This paper covers both Decimation-in-Time (DIT) and Decimation-in-Frequency (DIF) methods of computation to give flexibility in programming and to demonstrate the results of parallelization on both methods.
