control bus
In a digital computer, the signal paths that carry commands from the instruction decode logic to various functional units such as the ALU, memory address register, memory data register and other buffers.
Named by analogy with the address bus and data bus, each of which carries a set of related signals, the signals carried by the control bus are more varied and independent.Last updated: 2018-01-29
