Instruction Cycle
The sequence of operations that a CPU performs to execute an instruction, typically including fetching, decoding, and executing the instruction.
Control Signals
Signals generated to control the operations of different components in a computer system during instruction execution.
Micro Operations
The basic operations involved in executing macro instructions, including data movement and transformations at the micro level.
Hardwired Control
A type of control unit design where the control signals are generated by fixed logic circuits.
Micro-Programmed Control
