e Virtual Channel (VC) flow control mechanism is critical to the performance and energy problem of NoC. This mechanism suffers from some drawbacks such as contention, lack of high buffer utilization, HoL blocking and higher cost. First of all, we introduced a low cost VC mechanism (SMF) that has same functionality performance as a conventional static VC mechanism (CVC). An SMF router consumes 8% less area and 9% less power as compared to a conventional router that is confirmed by our synthesis results. We took the advantage of SMF architecture and introduced an adaptive model of VC (SAMF) to improve buffer utilization of an NoC channel. In a 4 × 4 mesh SAMF NoC with contention oriented traffic, 19% throughput and 23% latency improvements are gained with a 5% decrease in the area and 4% decrease in the power as compared to CVC. Another interesting feature of the SAMF model is to achieve higher performance for a lower hardware overhead as compared to the DAMQ model.
