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.

Abstract: An integrated circuit (IC) based detection circuit for determining a strap value and a method of detecting a digital strap value. In one embodiment, the detection circuit includes: (1) a first receiver including transistors having first electrical characteristics that define a first threshold for the first receiver, the first receiver operable to generate a first binary digit based on an input signal and the first threshold and (2) a second receiver including transistors having second electrical characteristics that differ from the first electrical characteristics and define a second threshold for the second receiver that is lower than the first threshold, the second receiver operable to generate a second binary digit based on the input signal and the second threshold, the first and second binary digits indicating whether the strap value lies above the first threshold, between the first and second thresholds or below the second threshold.
