A method, system, apparatus, and architecture are provided for detecting failure of a PCIe endpoint device by scanning an extended configuration space for each connected PCIe endpoint device to detect a first PCIe endpoint device that supports advance status reporting, and then by programming a first predetermined value and a second predetermined value, respectively, into an endpoint response register and a root complex request register of a dedicated memory control word in the extended configuration space for the first PCIe endpoint device, where the second predetermined value signals a request to the first PCIe endpoint device to update the endpoint response register of the dedicated memory control word with a new status value so that, after a minimum specified delay, a report that the first PCIe endpoint device has failed may be generated in response to detecting that the first predetermined value is stored in the endpoint response register.

A channel stream is received and demultiplexed into a video packetized elementary stream (PES), audio packetized elementary stream (PES), and program clock reference (PCR). Indexing circuitry stores the video PES and the audio PES in a buffer, locates a presentation time stamp (PTS) in the video PES and stores that PTS in the buffer, locates a start of each group of pictures (GOP) in the video PES and stores those locations in the buffer, and locates a PTS in the audio PES and stores that PTS in the buffer. Control circuitry empties the buffer of an oldest GOP in the video PES if the PCR is greater than the PTS of a second oldest GOP stored in the buffer, and empties the buffer of each PES packet of the audio PES that has a PTS that is less than the PTS of the oldest GOP stored.

Implementations of power management in a device are described. The device includes a power driver configured to manage power supply to one or more components in system-on-chip (SOC) hardware. The device further includes power subsystems configured as drivers for controlling the components of the SOC hardware and a user interface configured to receive a selected power mode as an input and identify profiles of one or more applications being executed in the device. Based on the selected power mode, the power driver directs the power subsystems to change a mode of operation of at least one component determined from the profiles of the one or more applications being executed.
