Note: See Threading and Tasks FAQ for more examples.. Overview. Chrome has a multi-process architecture and each process is heavily multi-threaded. In this document we will go over the basic threading system shared by each process. The main goal is to keep the main thread (a.k.a. "UI" thread in the browser process) and IO thread (each process' thread for handling IPC) responsive.

Apr 09, 2014· We don't, and don't currently have any plans to do so. The JPEG format is not very well-suited for GPU decompression. One part of it is, the YUV -> RGB colorspace conversion, and we might consider doing that on the GPU someday, but there are complications for that as well (e.g. shipping the raw image over to the GPU process).
