Code Convertor-Binary to Uniform Minimal Switching Representation (UMSR)

The low-power arithmetic design has become a very important aspect for recent compact electronic gadgets. The need to minimize dynamic power dissipation is vital for combinational circuits. Switching activity is a vital reason for the dissipation of power in combinational circuits, which includes activities like spurious pulses, called glitches. Functional transition and glitch are two types of signal transitions. A glitch is an unnecessary, momentary error in the system before the signal reaches to the anticipated value. Before reaching a stable state, there can be changes in the state of the signal, called glitches. Every toggling causes dissipation of power as a result of charging and discharging of gate capacitance. In the proposed method i.e., uniform minimal switching decimal representation, the increase in the number of 1's serially there will be an increase in the current and hence there are no glitches compared to binary code, where a number of 1's increases at different places. This type of coding has high linearity performance by reducing the clock feed-through effect especially in switching between multiple transistors. In the proposed method, one can prove that uniform minimal switching decimal representation acts as a number system so that all arithmetic operations can be done. In this paper Implementation of UMSR (Uniform minimal switching representation also known as Thermometer code) is carried out using Field Programmable Gate Arrays (FPGA).
