Embodiment Construction

[0017] The inventor of the present invention aims at hardware resources such as CPU, GPU, high-speed hard disk, video and audio board card in the existing image / video post-processing software to work relatively independently, will waste hardware resources greatly like this, cause the efficiency of program production to be very low question. Through a multi-task parallel scheduling method, the existing CPU, GPU, high-speed hard disk, video and audio board and other hardware resources are scheduled in parallel, allowing them to work at the same time, thereby greatly improving the utilization of resources and improving the efficiency of program production. promote.

[0018] Generally speaking, enabling different hardware to work in parallel refers to scheduling hardware resources that can work at the same time in time so that they can complete different tasks at the same time. For example, when the CPU executes the algorithm, the hard disk can be scheduled at the same time. Allo...

Abstract

The embodiment of the invention discloses a multi-task parallel scheduling method, which comprises the steps of: receiving a plurality of tasks which have functions and are marked with types; checking whether the tasks have execution conditions or not; and simultaneously starting a plurality of tread scheduling hardware resources. The invention further discloses a multi-task parallel scheduling device. Through applying the method and the device, a central processing unit (CPU), a graphic processing unit (GPU), a high-speed hard disk, a video and audio card and other hardware resources can be scheduled in parallel and work at the same time, accordingly, the utilization rate of the resources is greatly increased, so the programming efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of program production, in particular to a multi-task parallel scheduling method. Background technique [0002] In the image / video post-processing software, due to the particularity of the software, there are various hardware resources, including CPU, GPU, high-speed hard disk, video and audio boards, etc. These hardware resources need to be accessed in the post-processing software, such as reading material data from the disk, using the CPU to execute algorithms and interface reality, needing the GPU for graphics rendering, and using video and audio boards for image and sound Output. [0003] However, when the inventor of the present invention realized the present invention, he found that there were at least the following technical defects in the prior art: hardware resources such as CPU, GPU, high-speed hard disk, and video and audio boards were relatively independent. When using one resource, the next res...
