Abstract

The invention discloses an image processing method and device in GPU vitualization, and relates to the technical field of GPU vitualization. The image processing method and device in GPU vitualization solve the problem that because a front-frame image and a rear-frame image are compared through a CPU, burdens of the CPU are large in the prior art. The method comprises the steps that the current-frame image is obtained through a GPU; differentiated comparison instructions are received, and a front-frame image is obtained; according to the differentiated comparison instructions, a difference image between the current-frame image and the front-frame image is obtained and the position of the difference image is obtained; the position of the difference image and the difference image are sent to a system memory. The embodiment of the image processing method and device is applied to the image processing process in GPU vitualization.

Description

technical field [0001] The present invention relates to the technical field of GPU virtualization, in particular to an image processing method and device in GPU virtualization. Background technique [0002] In order to meet the requirements of a large number of customers for 3D applications such as engineering drawing, companies such as Microsoft and Citrix have provided GPU (Graphic Processing Unit, Graphics Processing Unit) virtualization for video and graphics applications in VDI (Virtual Desktop Infrastructure, virtual desktop infrastructure) application scenarios. Speed ​​up processing. Among them, the common method of GPU virtualization in the VDI scene is that when the host side obtains the 3D command from the virtual machine, the 3D command is passed to the GPU in the host side, and the GPU processes the rendering according to the 3D command, Get the current frame image, send the current frame image generated after rendering to the system memory, and the CPU (Centra...
