Memory-aware multiobjective design space exploration of heteregeneous MPSoC

This paper discusses multiobjective exploration of heterogeneous MPSoC design space using a method based on NSGA-II evolutionary algorithm. Key feature of the proposed method is separation of computation and communication which enables exploration of mapping computation to processors and communication to memory elements. In this paper two approaches to mapping and scheduling are presented and compared: (1) single-phased, where tasks and communication channels are mapped to processor and memories simultaneously, and (2) two-phased, where mapping of tasks to processors is done in first phase, followed by mapping of communication channel to memories in the second phase.
