In this work we propose a TCMS (Tightly Coupled Mesochronous Synchronizer)-based architecture of Globally-Asynchronous Locally-Synchronous (GALS) Network-on-Chips (NoC). The NoC is based on the GigaNoC approach, a scalable NoC featuring packet-switched wormhole routing. At a clock frequency of 750MHz a link bandwidth of up to 6 GByte/s is achieved. To provide a high computational performance, the processing engines (PEs) are based on the CoreVA VLIW architecture. The resource efficiency of mesochronous (TMCS-based) and asynchronous (FIFO-based) communication links is analyzed. In addition an asynchronous coupling of the PE to the switch boxes is evaluated. This allows for multi-voltage/multi-frequency scenarios, where the performance of each PE is adapted to the current performance requirements. Analyses have shown, that TCMS-based communication links and asynchronously coupled PEs allow for the high efficiency of GALS-based NoCs with moderate additional resource requirements. |
