Parallelized sub-resource loading for web rendering engine

High-performance web browsers would be more emphasized in the commercial electronic devices including smart phones, tablet PCs, netbooks, laptops, and smart TVs. On the other hand, the web browsers still experience performance degradation due to the increase of resources provided on a web page. In fact, web pages with a large number of images require a very complex rendering operations. In this paper, we propose a parallel web browser for rapid web rendering operations with exploiting thread-level parallelism. The proposed architecture parallelizes the sub-resource loading operation on various platforms including the conventional PC system and the mobile embedded system. The proposed parallel sub-resource loading operation achieves a maximum speedup of 1.87 in a quad-core system. For the dual-core embedded system, a maximum speed-up is as large as 1.45.
