Micro-programmed control units employ control signals that dictate operations within the CPU.
Branching in micro-program technology requires conditional checks to navigate different instruction paths.
Differences between horizontal and vertical micro-programming techniques can significantly impact efficiency and memory use.
A unit that uses a sequence of micro-instructions stored in memory to control the operations of the computer.
A register that keeps track of the address of the current micro-instruction being executed.
The mechanism that allows the control unit to alter the flow of execution based on certain conditions.
A method where control signals are sent out in parallel allowing for simultaneous operations, potentially leading to memory wastage.
A technique that optimizes memory by using shorter micro-instructions, hence requiring more complex control logic.
