ABSTRACT:
A complex, say, N=5 or greater input terminal, mask decoder circuit which is useful in the design of ALUs in microprocessors is presented. The circuit avoids wiring and uses logic gates to make the connections between the input terminals receiving the control bit signals and the output terminals on which the mask signals are generated. This allows the mask decoder circuit to occupy a minimal amount of space on an integrated circuit.
