Abstract

This paper presents DSP code optimization techniques, which originate from dedicated memory address generation hardware. We define a generic model of DSP address generation units. Based on this model, we present efficient heuristics for computing memory layouts for program variables, which optimize utilization of parallel address generation units. Improvements and generalizations of previous work are described, and the efficacy of the proposed algorithms is demonstrated through experimental evaluation.
