Processor supports 4K displays on mobile devices

ARM has launched what is says is its highest performing and most power efficient 4K capable display processor. The Mali-DP650, which is optimised for 2.5K formats, is intended to drive new visual content and gaming experiences on mobile devices.

“The processor will enable mobile screens with multiple composition layers, for graphics and video, at full HD (1920 x 1080 pixels) resolutions and beyond while maintaining excellent picture quality and extending battery life,” claimed Mark Dickinson, general manager of ARM’s media Mali-DP650 is optimised for 2.5K formats, including WQXGA (2560 x 1600 pixels) for tablets and WQHD (2560 x 1440 pixels) for a mobile screen.

It can support up to seven composition layers but, by doubling the width of the AXI bus to 128bit, developers can increase the number of 4K composition layers available.

“Smartphones and tablets are increasingly … allowing people to securely download content once and carry it to view on whichever screen is most suitable. The ability to stream the best quality content from a mobile device to any screen is an important capability ARM Mali display technology delivers,” Dickinson added.
