In this paper the design of error detection circuits for split-parity codes is investigated. In a split-parity code the linear parity bit is split into two nonlinear check bits. Split-parity codes, like parity codes, detect all odd errors with certainty; all even errors - which remain undetected by parity - are detected with a probability of 50%. It is shown that a large variety of split-parity codes exist which can be utilized for the optimization of error detection circuits with respect to area and error detection probability. It is demonstrated that split-parity codes are a cost-effective possibility to design error detection circuits.
