Abstract: A parity predict circuit for an M-level N'th power Galois arithmetic gate using binary logic elements and a method of the designing thereof is disclosed. The method involves an algorithm that the logic designer utilizes to visually analyze the output of the arithmetic gate using a heuristic technique to determine the procedure for intercoupling the outputs of the gate's 1 through m-1 levels of parity trees as inputs to the parity predict parity tree. This visual analysis obviates the laborious mathematical treatment of the arithmetic gate priorly utilized to design a parity predict network.
