A low latency wormhole router for asynchronous on-chip networks
Asynchronous on-chip networks are power efficient and tolerant to process variation but they are slower than synchronous on-chip networks. A low latency asynchronous wormhole router is proposed using sliced sub-channels and the lookahead pipeline. Channel slicing removes the C-element tree in the completion detection circuit and converts a channel into multiple independent sub-channels reducing the cycle period. The lookahead pipeline uses the early evaluation protocol to reduce cycle period. Using the lookahead pipeline on the pipeline stages with the maximal cycle period improves the overall throughput. The router is a pure standard cell design implemented by a 0.13
