摘　　要：广泛使用的WebKit内核嵌入式浏览器因具有良好的设计架构和优良的跨平台特性已被移植到许多嵌入式平台上。由于嵌入式平台的硬件多样性,WebKit开源版本并没有充分利用嵌入式平台的特点。通过研究WebKit显示系统,实现了充分利用嵌入式硬件加速渲染与软件渲染特点的软硬件混合渲染层。该混合渲染层解决了嵌入式平台上全功能浏览器运行缓慢造成用户体验较差的问题。经对比测试验证了该混合渲染层的可行性,与原始版本相比网站打开时间减少48%以上,网页动画渲染速度提高130%以上。Widely used WebKit of excellent architecture has been ported to many embedded platforms, with excellent cross-platform features. Due to the diversity of hardware for embedded platforms, WebKit open source version does not take full advantage of the characteristics of embedded platforms. Through studying WebKit render architecture, taking full advantage of the embedded hardware feature and the benefit of the software rendering design, a hardware and software fusion render layer was designed. This layer sped up the browser rendering on the embedded platform and improved the user experience. The layer was verified, the time of opening website was reduced by 48% and the speed of rendering of html animation increased by 130% compared to the original WebKit.
