A SystemC QoS router design with virtual channels reservation in a wormhole-switched NoC

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.
