At first, a survey on packet justify; TEXT-INDENT: 18pt; MARGIN: 0cm 0cm 0pt" There are two major groups ofacket justify; TEXT-INDENT: 18pt; MARGIN: 0cm 0cm 0pt" We propose a novel idea forlow power packet justify; TEXT-INDENT: 18pt; MARGIN: 0cm 0cm 0pt" We have implemented our approaches using FPGA and compared the results with other available solutions. The presented results show improvement in power consumption without significant hardware cost in comparison to other solutions. Additionally, different practical and software optimization techniques have been discussed in details. Keywords: Low Power TCAM, Multi-Match Packet ltr"
