Abstract: Disclosed herein is a region-based reference management system using in video frame encoding. Source content, such as video game streaming or remote desktop sharing, that includes scene changes or significant instantaneous changes in a region from one frame to the next can present encoding challenges. Techniques disclosed herein use hints about changes in regional frame content, dissect frame content into regions, and associate the dissected regions with stored reference frame data using the hints and information about the regions to more efficiently encode frames.

Abstract: A technique for varying firmware for different virtual functions in a virtualized device is provided. The virtualized device includes a hardware accelerator and a microcontroller that executes firmware. The virtualized device is virtualized in that the virtualized device performs work for different virtual functions (with different virtual functions associated with different virtual machines), each function getting a “time-slice” during which work is performed for that function. To vary the firmware, each time the virtualized device switches from performing work for a current virtual function to work for a subsequent virtual function, one or more microcontrollers of the virtualized device examines memory storing addresses for firmware for the subsequent virtual function and begins executing the firmware for that subsequent virtual function. The addresses for the firmware are provided by a corresponding virtual machine at configuration time.

Abstract: Integrated circuit layouts are disclosed that include metal layers with metal tracks having separate metal sections along the metal tracks. The separate metal sections along a single track may be electrically isolated from each other. The separate metal sections may then be electrically connected to different voltage tracks in metal layers above and/or below the metal layer with the separate metal sections. One or more of the metal layers in the integrated circuit layouts may also include metal tracks at different voltages (e.g., power and ground) that are adjacent to each other within a power grid layout. The metal tracks may be separated by electrically insulating material. The metal tracks and the electrically insulating material between the tracks may create capacitance in the power grid layout.

Abstract: A technique for recovering from a hang in a virtualized accelerated processing device (“APD”) is provided. In the virtualization scheme, different virtual machines are assigned different “time-slices” in which to use the APD. When a time-slice expires, the APD stops operations for a current VM and starts operations for another VM. To stop operations on the APD, a virtualization scheduler sends a request to idle the APD. The APD responds by completing work and idling. If one or more portions of the APD do not complete this idling process before a timeout expires, then a hang occurs. In response to the hang, the virtualization scheduler informs the hypervisor that a hang has occurred. The hypervisor performs a function level reset on the APD and informs the VM that the hang has occurred. The VM responds by stopping command issue to the APD and re-initializing the APD for the function.

An encoder partitions a video or image frame into a plurality of sub-frame blocks. For each sub-frame block, the encoder selects a subset of the original pixel values based on one or more criteria.

The encoder also includes the encoding vectors in the encoded block, wherein the encoding vectors are calculated based on the color parameter differences between each pair of the selected subset of pixel values. The encoder also includes metadata specifying the encoding mode in the encoded block.

Abstract: A method for dynamic scaling of content luminance and backlight level includes determining, using one or more processors of a display system, an ambient light level of a local environment proximate the display system. Based on the ambient light level being brighter than a first ambient light threshold, it is determined that the display system is in a normal room or a bright environment. A minimum viewable threshold representing a minimum pixel luminance value perceivable by a user in the ambient light level of the local environment is determined. The method further includes generating a modified display image by shifting the pixel luminance values of one or more pixels of an input image such that a darkest pixel value of the modified display image is equal to or greater than the minimum viewable threshold before transmitting the modified display image for display.

The segregated image is generated because the segregated image may be compressed more efficiently than the original image and the delta image.
