PROJECT TITLE :

Traffic-Based Virtual Channel Activation for Low-Power NoC

ABSTRACT:

A massive quantity of leakage power may be saved by increasing the quantity of idle virtual channels (VCs) during a network-on-chip (NoC). Low-leakage power switch is proposed to permit saving in power dissipation of the NoC. The proposed NoC switch employs power offer gating to cut back the power dissipation. 2 power reduction techniques are exploited to style the proposed switch. Adaptive virtual channel technique is proposed as an efficient technique to reduce the active space using hierarchical multiplexing tree. Moreover, power gating (PG) reduces the common leakage power consumption of proposed switch. The proposed techniques save up to ninety seven% of the switch leakage power. In addition, the dynamic power is reduced by forty%. The traffic-primarily based virtual channel activation (TVA) algorithm is used to work out the traffic status and send adaptation signals to PG units to activate/deactivate the VCs. The TVA algorithm optimally utilizes VCs by deactivating idle VCs to guarantee high-leakage power saving with high throughput. TVA is an economical and flexible algorithm that defines a group of parameters for use to attain minimum degradation in NoC throughput with most reduction in leakage power. The full network average leakage power has been reduced by up to 80% for 2-D-mesh NoC with throughput degradation inside only 1%. For two-D-torus NoC, a saving in power of up to eighty four% is achieved with
