Optimization techniques and benchmarks of the finite impulse response (FIR) filters on the blackfin processor

Abstract

Digital Signal Processing (DSP) algorithms, which are commonly used in any customer electronics devices such as handheld devices, have evolved to a more and more complex algorithm. However, some of the basic algorithm kernel, such as the FIR filter, can be found in many DSP based application. Thus, our work emphasizes on the optimization techniques to reduce the execution time of the Finite Impulse Response filter. Our optimization techniques are carried both in C program and in assembly program.
