Abstract

Many digital signal processors (DSPs) and also microprocessors are employing the single-instruction multiple-data (SIMD) paradigm for controling their data paths. While this can provide high computational power and efficiency, not all applications can profit from this feature. One important application of DSPs are recursive filters. Due to their data-dependencies they can not exploit the capabilities of SIMD-controlled DSPs. This paper introduces enhancements of the SIMD control paradigm to accommodate recursive filters. Three methods for calculating recursive filters on SIMD-controlled DSPs and their requirement’s for control and data transfer are presented. Their performance and hardware requirements are evaluated to determine the most efficient solution in terms of the AT-product.
