Design and Implementation of Area and Power Efficient Low Power VLSI Circuits through Simple Byte Compression with Encoding Technique

Abstract

Transition activity is one of the major factors for power dissipation in Low power VLSI circuits due to charging and discharging of internal node capacitances. Power dissipation is reduced through minimizing the transition activity by using proper coding techniques. In this paper Multi coding technique is implemented to reduce the transition activity up to 58.26%. Speed of data transmission basically depends on the number of bits transmitted through bus. When handling data for large applications huge storage space is required for processing, storing and transferring information. Data compression is an algorithm to reduce the number of bits required to represent information in a compact form. Here simple byte compression technique is implemented to achieve a lossless data compression. This compression algorithm also reduces the encoder computational complexity when handling huge bits of information. Simple byte compression technique improves the compression ratio up to 62.5%. As a cumulative effort of Simple byte compression with Multi coding techniques minimize area and power dissipation in low power VLSI circuits.
