A virtualized multimedia processing method and system

Abstract

A method and system for virtualizing multimedia processing are provided. The system includes a virtualized hardware management module, a plurality of operating systems and hardware modules. The methodcomprises the following steps: a hardware priority configuration layer receives operation instructions from different operating systems to hardware modules, and configures the priority order of eachoperation instruction; The hardware operation instruction distribution layer serially distributes each operation instruction to the hardware access layer according to the priority order of each operation instruction. The hardware access layer sends the received operation instructions to the hardware module in turn and receives the execution result of each operation instruction from the hardware module and sends the execution result to the hardware priority configuration layer through the hardware operation instruction distribution layer; The hardware priority configuration layer sends the execution result corresponding to each operation instruction to the corresponding operating system. Through the scheme, the virtualization operation of the private hardware module can be realized, and the power consumption of the private hardware module can be reduced.

Description

technical field [0001] The invention relates to the field of hardware virtualization, in particular to a virtualized multimedia processing method and system. Background technique [0002] With the development of science and technology and the progress of society, virtualization technology has been widely used. At present, virtualized computing is mainly applied to personal computers and server devices with X86 architecture. Specifically, an on-demand allocation / dynamically scalable hardware pool is formed through virtualization technology. Advanced virtualization technology can improve the utilization efficiency of the entire system. . The core idea of ​​virtualization is: abstract or virtualize computing resources, and there is a virtual machine monitor that supports several operating systems concurrently, and arbitrates several operating systems to use shared hardware resources (processor / peripherals / memory and IO, etc.). [0003] Such as figure 1 As shown in FIG. 2 , ...

AI Technical Summary

Problems solved by technology

[0005] For this reason, it is necessary to provide a technical solution for virtualized multimedia processing, which is used to solve the problem that the existing architecture cannot realize the virtualization of private hardware modules (such as PMU and VPU modules)
