Abstract

Embedded processor-based systems allow for the tailoring of the on-chip memory architecture based on application specific requirements. We present an analytical strategy for exploring the on-chip memory architecture for a given application, based on a memory performance estimation scheme. The analytical technique has the important advantage of enabling a fast evaluation of candidate memory architectures in the early stages of system design. Many digital signal-processing applications involve array accesses and loop nests that can benefit from such an exploration. Our experiments demonstrate that our estimations closely follow the actual simulated performance at significantly reduced run times
