Abstract

A GALS Networks-on-Chip (NoC) router with QoS support is presented. It supports multi-levels of QoS including hard guarantees (Hard GT)and statistical guarantees (Soft GT). In hard GT, novel Rate-control schedule is adopted to decouple the relationship between bandwidth and delay. And then, different from other routers whose bandwidth left was absorbed by only BE packets, we also support soft GT to further maximize network performance. In Soft GT, VC is dynamically allocated and performance is improved. Simulation shows that our router supports QoS well with little overhead.
