Abstract
A clock control technique allows reducing the power consumption of devices connected to a computer bus. Individual idle devices can be disconnected from the bus clock by a device clock controller and placed in a low-power state without waiting for all devices on the bus to go idle. When individual devices are idle, transactions on the bus are monitored and unclaimed transactions are claimed by the device clock controller, which then forces a retry of the transaction and reconnects the clock to the idle devices. This brings these devices from the low-power state to a full power state, where they are capable of claiming the transaction when it is retried.
