As today’s modern autonomous robots consist of many sensors, multiple processors and artificial intelligence software. For this, it draws data from the input sensor and process them into meaningful information with the help of an on board microcontroller unit, MCU otherwise known as the processor. It is also responsible for taking decisions based on the information provided by the sensors and therefore, tells the output devices how to function and do a task. Processors are the main thinking and evaluating part of any of the robot. Main purpose of the processors and the CPU is performing of functions out of which most of them are performed using multipliers in the processor. Compressor are mainly used for designing different type of power efficient multipliers. In this work, a 3:2 And 4:2 compressor are designed using XOR-XNOR circuit. This innovative design structure of 3:2 and 4:2 compressor helps in power consumption and delays as compared to todays existing designs. The simulated results shows improvement in the performance parameters. It indicates decrement in the power consumption by 13.46% for 3:2 compressor and 25.29% for 4:2 compressor at 2.5v obtained from the comparison with the existing state of art.
