Abstract
A circuit (10) for producing a microprogram memory address (16). This circuit includes circuitry (18I, 18J) for selecting a plurality of condition codes. Additionally, the circuit includes logic circuitry (20) for producing a result by performing logic operations using as operands the selected plurality of condition codes. The result of the logic operations forms a first portion (LSB', or LSB' and NLSB') of the microprogram memory address.
