 Parallel FFT Implementations on Fixed-Point DSP-Cores with Subword-Parallelism
Fast Fourier transform algorithms are vital in many digital signal-processing (DSP) applications.
In here, both, radix-2 and radix-4 complex fast Fourier transform (FFT) implementations for fixed-point applications, using single instruction multiple data (SIMD) instructions and sub-word parallelism (SWP) is presented.
It is shown that data management, and memory access are key to unleashing the arithmetic power of highly parallel digital...
