Abstract

Applications for system on chips become more and more complex. Also the number of available components (DSPs, ASICs, Memories, etc.) rises continuously. These facts necessitate a structured method for selecting components, mapping applications and evaluating the chosen configuration and mapping. In this work we present a methodology for the last named. We will consider optimization of memory allocation and task scheduling as a packing problem and minimize needed memory area. The results can be used as one element of an automated performance analysis for a given system on a high abstraction level. This analysis is essential for establishing a framework that iterates over a large quantity of possible systems. Considering a part of the H.264 codec as an example we will illustrate the results. Furthermore we will show that results can be retrieved fast compared to other NP-hard problems due to intelligent formulation of conditions within the linear program.
