A new firmware update for the PlayStation Portable (PSP) will add Google's search engine to the portable console, Sony announced today.

Gamers who upgrade their PSPs to the version 4.0 firmware, which will be available "soon", will find Google on the handheld's Cross Media Bar (XMB) menu, according to Eric Lempel, director of the PlayStation Network, on the PlayStation blog.

"This new upgrade replicates the Google internet search experience, delivering the same search results that you’d get at www.google.com. And with a search history recall of 20 items, web searches couldn’t be easier," he wrote.

Google will appear in the network section of the XMB. Also new in the version 4.0 firmware will be the ability to change viewing speed when playing back videos from Memory Stick cards.

Sony has regularly offered updates to the firmware of the PSP since it was launched and through such updates has added a host of new features. Previous updates have added features such as a web browser and support for a wider range of video formats.
