NoC is the communication media in a SoC (System on Chip) environment decoupling computation from communication. This paper presents the design of an on-chip network router with Quality-of-Service (QoS) support. The router uses a virtual channel architecture with a priority-based scheduler to differentiate between multiple connections with various QoS requirements sharing the same physical channel. A SystemC based methodology is used to achieve an RTL simulation of the design.
