DSP Filter Kernels Preliminary Benchmarking for Recurrent Data-flow Architecture

摘要

The article discusses the results of a preliminary assessment of the data-flow recurrent architecture's performance on a subset of digital signal processing key tasks. Various implementations of vector convolution, FIR filters, IIR filters, adaptive filter, and 256-Point-In-Place FFT are evaluated. The implementation of the listed algorithms is based on the TMS320C55x DSP Library. The preliminary results showed that the performance of the recurrent architecture based on data-flow principles is not inferior to the TMS320C55x, based on von Neumann principles, in terms of the number of computation cycles. Architecture improvement suggestions are presented.
