Mapping of pipeline flow chart onto mesh-based multi-core NoC architecture

Among current outstanding research problems in NoC Design, mapping application onto NoC is one of the core issues to be explored. In this paper, we propose two methods for mapping a pip elined flow chart onto mesh-based NoC system: Communication Length Concerned (CLC) method and Space Restricted (SR) method after a simple pre-process. The former significantly reduces the latency and energy consumption in inter-core communication while latter method provides a trade-off for run-time mapping based on the former one. Results show that, compared with normal mapping, the CLC method reduces about 43.3% and 28.6% in communication latency and energy consumption, respectively; while the SR method reduces about 37.6% communication latency and 24% energy consumption. The two methods discussed in this paper could be used as guidance for mapping pipeline flow charts on homogenous mesh-based NoC architectures.
