A Modified NoC Router Architecture with Fixed Priority Arbiter

NoC is an approach in designing communication subsystems between intelligent property (IP) cores in SOC with greater efficiency. RKT router switch that handles accurate localizations of the faulty parts of the dynamic NoCs. The RKT- NoC switch is highly reliable when compared with ordinary NoC due to the addition of error detection mechanism in the design and it avoids the deadlock and livelock problems. NOC means network on chip is a new method for on chip communication to solve a problem that challenges system on chip. The proposed method adoptes an fixed priority arbiter. Arbiter is used in network on chip when number of input are requested for same output port, the arbiter has generate the grant signal on the basis of that number of input port getting a priority and the input port transmit a packet to output port. The proposed method distinguish the path of data packets thereby avoiding the collision between the data packets. The arbitration should guaranteed the fairness in scheduling, avoid starvation, and provide high throughput.
