This paper explain the Enhanced detection of Double adjacent Errors in Hamming codes. In 1950’s Richard Hamming invented the Hamming code. Designed to correct single bit errors. Hamming Codes are used in computing, telecommunication, and other applications. Codes are simple to construct for any word length. It can be easy to Encode and decode.2D Hamming Product Code is used to detect and correct errors. But, this fails to detect adjacent errors . Detecting double adjacent errors using Selective Bit Placement Algorithm. In this paper the algorithm for hamming code is discussed and then implementation of it in verilog is done to get the result. Here code is implemented in verilog in which 4 bit of information data is transmitted. Delay, area and power analyses were carried out using Xilinx ISE-13.2.The results obtained are presented and compared. The enhanced detection is achieved by selective bit placement strategy.
