In this paper, the authors propose a simple and efficient mechanism to increase the throughput of an adaptive router in Network-on-Chip (NoC). One of the most serious disadvantages of fully adaptive wormhole routers is its performance degradation due to the routing decision time. The key idea to overcome this shortcoming is the use of different clocks in a head flit and body flits, because the body flits can be forwarded immediately and the FIFO usually operates faster than route decision logic in an adaptive router.
