The Google Chrome OS should begin appearing on netbook computers in the second half of 2010, Google said in a blog post.
Google is already talking to "multiple" companies about the Chrome OS project, it added.
Prototypes of Arm-based netbooks began appearing last month at the Computex show in Taiwan and Google's support for the architecture could give it a significant boost. Microsoft's mainstream Windows operating system doesn't run on Arm chips so many manufacturers were talking about using Linux or a version of the Google Android operating system. It's not immediately clear how much the two operating systems share in common code but Google said they are aimed at very different devices.
"Google Chrome OS is a new project, separate from Android," it said. "Android was designed from the beginning to work across a variety of devices from phones to set-top boxes to netbooks. Google Chrome OS is being created for people who spend most of their time on the web."
While Google is initially looking at the netbook segment of the market it might compete with Microsoft and Apple on larger, internet-centric machines.
Chrome OS is "being designed to power computers ranging from small netbooks to full-size desktop systems," said Google.
