Abstract

This three-part programmed logic array (PLA) includes array I which operates on operand A, array II which operates on operand B and array III which is located between I and II on the same chip and comprises two-bit partition circuitry fed by I and II. In the example shown the logic function to be implemented includes three functions of two data fields: Function I of data field A; Function II of data field B; and the comparison of data fields A and B to check if they are equal.
