Abstract

A webpage update method and apparatus based on synthetic rendering acceleration. When a browser runs dynamic JavaScript code to change a CSS attribute corresponding to a layer attribute in a webpage element, a kernel thread correspondingly updates the attribute of a layer where the webpage element is located in a current webpage snapshot of the kernel thread; a synthesis thread correspondingly updates the attribute of a corresponding layer in a current webpage snapshot of the synthesis thread according to the updated webpage snapshot of the kernel thread, and then performs a synthesis operation according to the current webpage snapshot after update, so as to update the webpage. The technical solution omits the re-typesetting and webpage snapshot copy of the kernel thread and the pre-drawing step of the synthesis thread, and improves the processing efficiency of webpage update and dynamic webpage display performance.

Description

technical field [0001] The present invention relates to the technical field of web page rendering, in particular to a method and device for updating web pages based on composite rendering acceleration. Background technique [0002] At present, browsers generally adopt a multi-threaded rendering acceleration architecture to make full use of the hardware performance of multi-core CPU (Central Processing Unit, central processing unit) and GPU (Graphic Processing Unit, graphics processing unit), and to avoid UI (User Interface, user interface). Interface) Thread blocking causes user operations to be unsmooth. Among them, composite rendering acceleration uses more rendering acceleration architectures, and improves rendering performance by dividing web pages into multiple layers. Under the composite rendering acceleration architecture, the browser groups all web page elements according to predetermined rules, making them belong to a specific layer, and organizes all layers into a...
