Compiler-directed application mapping for NoC based chip multiprocessors

Published:13 June 2007Publication History

ABSTRACT

The problem attacked in this paper is one of automatically mapping an application onto a Network-on-Chip (NoC) based chip multi-processor architecture in a locality-aware fashion. The proposed compiler approach has four major steps: task scheduling, processor mapping, data mapping, and packet routing. Our experimental result clearly shows that the proposed framework reduces energy consumption of our applications significantly (27.41% on average over a pure performance oriented application mapping strategy) as a result of improved locality of data accesses.
