Low Power and High Performance Reconfigurable Routers

Abstract? An energy-efficient network-on-chip (NoC) is presented for possible application to high-performance system-onchip(SoC) design. Network-on-chip (NoC) designs are based on a latency, power dissipation or energy and the balance is defined at design time. Setting all parameters, such as buffer size, at design time can use either excessive power dissipation by router under utilization or a higher latency. It is today?s requirement. network-on-chip architecture is proposed to enhance the performance of on-chip communication. The condition whenever the application changes its communication pattern, e.g. a portable phone downloads a new service. Large buffer sizes can ensure performance during the execution of different applications, but these same buffers are mainly responsible for the router total power dissipation. Another condition is that by sizing buffers for the worst case latency incurs extra dissipation for the mean case, which is much more frequent. Router delivers better performance and requires smaller buffer size than that of a conventional network-on-chip (NoC). NoC architecture proposed in [1]?[3]has gained high popularity due to its simplicity and flexibility.Propose the use of a reconfigurable router, where the buffer slots are dynamically allocated to increase router efficiency in an NoC, even under rather different communication loads. In the proposed architecture, the depth of each buffer word used in the input channels of the routers can be reconfigured at run time. The reconfigurable router allows up to 52% power savings, while maintaining the same performance as that of a homogeneous router, but using a 64% smaller buffer size.
