Optimal saving in TCAM search power can be achieved with the combined strategy of both hardware-based techniques and a power friendly TCAM configuration. This letter proposes that a conditional precharging hardware scheme is used with a power aware TCAM configuration. In the traffic simulation results, the proposed scheme conservatively saved 72% of energy with unbiased traffic compared to no energy saving schemes for a sample design of 51272 TCAM block.
