GPU based parallel image processing at thin client

摘要

Disclosed herein is a computing device that includes: a processor; a graphic processing unit having N graphic processing cores, N being an integer greater than 1; a random access memory (RAM); a video port; a non-volatile memory, and a display processing unit. The non-volatile memory stores a virtual desktop client (VDC). The VDC can communicate with a first virtual machine (VM) of a hypervisor running on a remote computing device and receive an encoded image frame from the first VM; instruct the plurality of graphic processing cores to decode the encoded image frame in parallel; and generate a decoded image frame of the encoded image frame. The display processing unit can generate display signals representing the decoded image frame and transmit the display signals to the video port.

1. A computing device comprising:
a processor; a graphic processing unit having N graphic processing cores, N being an integer greater than 1; a random access memory (RAM), having a general memory area that is utilized by the processor, and a graphic memory area that is utilized by the graphic processing unit; a video port; a non-volatile memory storing a virtual desktop client (VDC) configured to, when executed at the processor,
communicate with a first virtual machine (VM) of a hypervisor running on a remote computing device and receive an encoded image frame from the first VM, wherein the encoded image frame include a plurality of encoded image tiles,store the plurality of encoded image tiles of the encoded image frame to the general memory area,copy a first group of N encoded image tiles of the plurality of encoded image tiles to the graphic memory area,instruct the N graphic processing cores to concurrently decode the first group of encoded image tiles, andgenerate a decoded image frame of the encoded image frame; and a display processing unit, configured to generate display signals representing the decoded image frame and transmit the display signals to the video port.
