Abstract: Power-saving techniques in computing devices through communication bus control start a timer when data is ready to be sent across a communication bus from a first terminus to a second terminus. While the timer is running, any data from any channel that is ready to be sent across the communication bus from the first terminus to the second terminus is accumulated. At expiration of the timer, all data is sent across the communication bus. By holding or accumulating the data in this fashion, unnecessary transitions between low-power states and active states on the communication bus are reduced and power is conserved. The timer may be set based on latency requirements of the data ready to be sent.
