摘要:  

With the increasing number of processing elements (PEs) integrated into a chip, the communication between the PEs becomes the performance bottleneck. Network-on-Chip (NoC) is a popular on-chip communication paradigm that can connect a large number of PEs thanks to its high scalability and efficiency. Nevertheless, the performance of such communication backbone is limited by two issues. First, hop-by-hop transmission results in time-consuming long-distance communication, especially when the network size grows. Second, improper resource management strategies cause unnecessary network contentions, which results in huge delay and drastically degrades the NoC performance, especially when the communication volume increases. To address these challenges, we propose a software and hardware collaborated methodology to design a novel NoC. (1) We propose (1) a software-defined point-to-point NoC architecture, ArSMART, enabling arbitrary packet routing and application-specific communication optimization, (2) a method to co-optimize task mapping and routing to accelerate computation and communication simultaneously, extending ArSMART to heterogeneous systems, and (3) a technique for parallel multipath transmission to fully utilize the parallelism in NoCs, further reducing transmission latency in ArSMART. The holistic design can effectively boost the NoC performance in application-specific many-core systems.
