Definitions of CONTROL BUS
Sort: Oldest first
In a digital computer, the signal paths thatcarry commands from the instruction decode logic to variousdifferent functional units such as the ALU, memory addressregister, memory data register and other buffers.Named by analogy with the address bus and data bus, eachof which carries a set of related signals, the signals carriedby the control bus are more independant.Some might include other signals such as timing (clock) andstatus under the term, further reducing its similarity toother busses.
