Abstract

Steady advancements in semiconductor technology over the past few decades have marked incipience of Multi-Processor System-on-Chip (MPSoCs). Owing to the inability of traditional bus-based communication system to scale well with improving microchip technologies, researchers have proposed Network-on-Chip (NoC) as the on-chip communication model. Current uni-processor centric modeling methodology does not address the new design challenges introduced by MPSoCs, thus calling for efficient simulation frameworks capable of capturing the interplay between the application, the architecture, and the network. Addressing these new challenges requires a framework that assists the designer at different abstraction levels of system design; This thesis concentrates on developing a framework for unified simulation environment for NoCs (fuse-N) which simplifies the design space exploration for NoCs by offering a comprehensive simulation support. The framework synthesizes the network infrastructure and the communication model and optimizes application mapping for design constraints. The proposed framework is a hardware-software co-design implementation using SystemC 2.1 and C++. Simulation results show the architectural, network and resource allocation behavior and highlight the quantitative relationships between various design choices; Also, a novel off-line non-preemptive static Traffic Aware Scheduling (TAS) policy is proposed for hard NoC platforms. The proposed scheduling policy maps the application onto the NoC architecture keeping track of the network traffic, which is generated with every resource and communication path allocation. TAS has been evaluated for various design metrics such as application completion time, resource utilization and task throughput. Simulation results show significant improvements over traditional approaches.
