Abstract
A serial multiply accumulator (MAC) for operation of two multiplications and one addition over Galois field is disclosed. The MAC includes a first element feeding circuit, a second element feeding circuit, a number of first calculating circuits and a second calculating circuit. By re-arranging the circuit design, many elements used in the conventional MAC, such as XOR gates and registers, can be saved. The present invention has an advantage of lower area cost.
