Networks must be able to transfer data from one device to another with acceptable accuracy. For most of the applications, a system must guarantee that the data received are identical to the data transmitted. Any time data are transmitted from one node to the next, they can become corrupted in passage. Many factors can alter one or more bits of a message. Some applications require a mechanism for detecting and correcting errors and some applications may require retransmission of error data packets. In this paper, it is proposed to implement Hamming (7, 4) code for data encoding and decoding in LPC1788ARM Cortex boards.The proposal is aiming for detecting and correcting the error without any retransmission of error data. As RISC processor is used, the speed of execution is high and also QoS (Quality of Service) Parameters are used for measurement purpose which enable this proposal can be useful for high speed real time applications. © 2005 - 2014 JATIT & LLS.
