This error checker predicts the parity of an eight-function arithmetic logic unit (ALU) and provides 100% error detection. It is based on several techniques, described in [*]. (Image Omitted) The eight functions, common to most ALUs, are designed to pass through the adder logic, taking advantage of the adder checks and circuitry.
