Abstract: Systems and devices configured to implement techniques for ensuring the completion of transactions while minimizing latency and power consumption are described. A device may be operably coupled to a bidirectional communications bus. A bidirectional communications bus may include a clock line and a data line. The device may be configured to determine if an initiated transaction corresponds to a device in a low power state. The device may pause the transaction. The device may replay portions of the transaction when the device is in an appropriate power state. The device may replay portions of the transaction using an override interface.

Abstract: A device for processing graphics data may include a plurality of graphics processing units. The device may include a fan to dissipate thermal energy generated during the operation of the plurality of graphics processing units. Each of the plurality of graphics processing units may generate a pulse width modulated signal to control the speed of the fan. The device may include one or more monitoring units configured to monitor a signal controlling the speed of the fan. One or more of the plurality of pulse width modulated signals may be adjusted based on the monitored signal. One or more of the plurality of pulse width modulated signals may be adjusted such that a signal controlling the fan maintains a desired duty cycle.
