碩士 === 國立臺灣大學 === 電子工程學研究所 === 99 === In this thesis, we proposed algorithm and architecture design for performance reduction in thermal-aware 3D network-on-chip (NoC). To ensure thermal safety and avoid huge performance back-off from the temperature constraint, run time thermal management is required. However the regulation of temperature requires throttling of the near-overheated router, which makes the topology become Non-Stationary Irregular Mesh (NSI-mesh). To successfully deliver packet in NSI-mesh, we propose a Transport Layer Assisted Routing (TLAR) secheme for thermal-aware 3D NoC. Based on the experimental results, the proposed routing scheme can significantly improve the performance and balance traffic load. For low cost implementation, we also propose memory reduction techniques, and we gain 1.7x throughput improvement for only 11.1% area overhead.
