Tolerating Soft Errors with Horizontal-Vertical-Diagonal-N-Queen (HVDNQ) Parity

A new error detection and correction methodology, defined as Horizontal-Vertical-Diagonal-N-Queen-Parity (HVDNQ), is proposed in this paper. This approach relies on five different types of parities: horizontal parity, vertical forward diagonal backward queen parity. method works an N X cell area can correct multi-bit upsets. The experimental analysis validates the effectiveness methodology by comparing its efficiency with existing methodologies. In varieties patterns such equilateral triangle, pentagon, hexagon etc., capability HVDNQ much better than methods.
