control bus









































in computer architecture,









































a control bus is part of the system bus, used by cpus for communicating with other devices within the computer. while the address bus carries the information about the device with which the cpu is communicating and the data bus carries the actual data being processed, the control bus carries commands from the cpu and returns status signals from the devices. for example, if the data is being read or written to the device the appropriate line (read or write) will be active (logic one).









































section::::lines.
control bus
bullet::::- clock signals. the signal on this line is used to synchronize data between the cpu and a device.









































bullet::::- reset. if this line is active, the cpu will perform a hard reboot.









































systems that have more than one bus master have additional control bus signals that control which bus master drives the address bus, avoiding bus contention on the address bus.
