Error detection & correction using horizontal-vertical-diagonal-shift method

This paper proposes a novel approach to detect and correct multi bit upsets using horizontal-vertical-diagonal-shift (HVDS) parity. Many of the errors occur when information is transmitted from one node to another node. Detection and correction of these errors is a must for many systems e.g. safety critical systems. Existing work on error detection and correction cover up to three bit errors (as far reviewed) in a data word. The proposed method can detect and correct up to 7 bit errors. Experimental studies show the effectiveness of the proposed method in comparison to existing dominant work.
