Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048]In operating systems that introduce threads, processes are usually used as the basic unit of resource allocation, and threads are used as the basic unit of independent operation and independent scheduling. For example, when a user runs an application program on an electronic device, the operating system creates a process and allocates resources to it. The resources include various tables, memory space, disk space, and I / O devices. Typically, when a user start...

Abstract

The invention discloses a task scheduling method and electronic equipment. The method includes: monitoring the system running state, the system running state including the state of a target process; according to the system running state, using a task scheduling policy corresponding to the target process to perform task scheduling; Wherein, the target process is a process related to virtual reality VR and / or augmented reality AR. The above method is used to alleviate the technical problems existing in the prior art that the operating system adopts a fair scheduling strategy that cannot meet the real-time display requirements of AR / VR devices, resulting in screen tearing and blurred screens, and achieves the technical effect of ensuring real-time display.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a task scheduling method and electronic equipment. Background technique [0002] Most of the existing VR (Virtual Reality; Virtual Reality) / AR (Augmented Reality; Augmented Reality) devices are developed based on general-purpose operating systems, such as the Android system. The task scheduling of the general system is relatively fair, so as to ensure that all tasks can obtain equal CPU (Central Processing Unit; central processing unit) resources. [0003] Since VR / AR devices have high requirements for real-time display, in order to reduce the display delay, VR / AR devices can adopt FBR (Front Buffer Rendering; Front Buffer Rendering) mode, and the FBR mode allows the GPU of VR / AR devices (Graphics Processing Unit; graphics processing unit) and the display controller write and read the same memory at the same time, thereby reducing the intermediate cache and reducing the dis...
