Abstract
A single-chip microprogrammable sequence controller includes a subroutine stack and conditional branching facilities. The controller performs a test and mask operation followed by comparison with a user-defined constant to effect a Boolean sum-of-product function. Address control logic includes a flag signal set by compare logic; the flag is available to a microinstruction decoder where it can be used during a subsequent conditional branch operation based on the setting of the flag.
