In 21st the role of wireless communications is huge in daily life applications but still power consumption by the applications is still concerned area in field of digital signal processing. Low power DSP architecture is required in all applications. Wireless communication exhibits the highest energy consumption in wireless sensor nodes. Given their limited energy supply from batteries or scavenging, these nodes must trade data communication for on-the-node computation. Due to the increasing complexity of VLSI circuits and their frequent use in portable applications, energy losses in the interconnections of such circuits have become significant.
