Publication number: 20220159286Abstract: Systems, apparatuses, and methods for reducing latency when consuming an encoded video bitstream in real-time are disclosed. A video encoder encodes a video bitstream and writes chunks of the encoded bitstream to a bitstream buffer. Prior to the encoder completing the encoding of an entire frame, or an entire slice of a frame, a consumer module consumes encoded chunks of the bitstream. In one implementation, to enable pipelining of the consumption with the encoding, the encoder updates a buffer write pointer with an indication of the amount of data that has been written to the bitstream buffer. The consumer module retrieves encoded data from the bitstream buffer up to the location indicated by the buffer write pointer. In this way, the consumer module is able to access and consume encoded video data prior to the encoder finishing encoding an entire frame or an entire slice of the frame.Type: ApplicationFiled: January 28, 2022Publication date: May 19, 2022Inventors: Ahmed M.

Publication number: 20220058048Abstract: 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.Type: ApplicationFiled: November 2, 2021Publication date: February 24, 2022Applicant: ATI Technologies ULCInventors: Yinan Jiang, Ahmed M. Abdelkhalek, Guopei Qiao, Andy Sung, Haibo Liu, Dezhi Ming, Zhidong Xu

Patent number: 11182186Abstract: 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.Type: GrantFiled: July 28, 2017Date of Patent: November 23, 2021Assignees: Advanced Micro Devices, Inc., ATI Technologies ULCInventors: Anthony Asaro, Yinan Jiang, Andy Sung, Ahmed M.

Patent number: 10452554Abstract: Systems, apparatuses and methods of adaptively controlling a cache operating voltage are provided that comprise receiving indications of a plurality of cache usage amounts. Each cache usage amount corresponds to an amount of data to be accessed in a cache by one of a plurality of portions of a data processing application. The plurality of cache usage amounts are determining based on the received indications of the plurality of cache usage amounts. A voltage level applied to the cache is adaptively controlled based on one or more of the plurality of determined cache usage amounts. Memory access to the cache is controlled to be directed to a non-failing portion of the cache at the applied voltage level.Type: GrantFiled: April 8, 2016Date of Patent: October 22, 2019Assignees: ADVANCED MICRO DEVICES, INC., ATI TECHNOLOGIES ULCInventors: Ihab Amer, Khaled Mammou, Haibo Liu, Edward Harold, Fabio Gulino, Samuel Naffziger, Gabor Sines, Lawrence A.
