The overall performance is analyzed by using Modelsim and Xilinx Tools. This coding method is implemented using Verilog HDL. The redundant bits are placed at bit positions 1, 2, 4 and 8. The equation is satisfied and so 4 redundant bits are selected. To find the number of redundant bits, Let us try P4.

In addition, 1 bit full adders are introduced in the Hamming distance estimator block, which reduces the device count. Encode a binary word 11001 into the even parity hamming code. So a novel multi coding technique is introduced to improve the efficiency of transition activity up to 52.3% on the bus lines, which will automatically reduce the dynamic power dissipation. In algorithm level the key aspect of reducing power dissipation is by minimizing transition activity and is achieved by introducing a data coding technique. This paper proposes power reduction analyzed through algorithm and logic circuit levels.
Reduced to a single check bit, Hamming codes and CRC are identical (x+1 polynomial) to parity. For example, with 3 bits distance, you can correct any 1 bit error OR detect any 2 bit error.

Then place the input message bits in all the positions where hammingCode j is not -1 in order where 0 < j < (r + m). Adding the Hamming code bits, you ensure some distance (as the number of differing bits) between valid codes. Initialize all the positions of redundant bits with -1 by traversing from i 0 to r 1 and setting hammingCode 2i 1 -1. Transition activity is one of the major factors that also affect the dynamic power dissipation. Initialize a vector hammingCode of size r + m which will be the length of the output message. In deep submicron low power CMOS VLSI design, the main cause of energy dissipation is charging and discharging of internal node capacitances due to transition activity. Advances in VLSI technology have enabled the implementation of complex digital circuits in a single chip, reducing system size and power consumption.
