"Google and their Chromebook is a great example of a browser with a tiny little operating system. It just shows what can be done" with good Internet connectivity, East said.

ARM had a small booth at MWC showing off prototype devices with multiple OSes. Also on display was a 10.1-inch Android tablet with Samsung's eight-core Exynos 5 Octa chip, which is based on ARM's latest Cortex-A15 processor.

East said the Cortex-A15 will ship in some products this year, though the chip is expected to become available in a wide number of devices next year. Cortex-A15 is currently available in only a handful of products like Google's Nexus 10 tablet, and a few prototype devices with the processor were shown at MWC.

Cortex-A15 replaces Cortex-A9, which is found in a large number of smartphones and tablets today. Cortex-A9 will live on and be repurposed for use in a range of devices, East said. For example, ARM and Nvidia redesigned Cortex-A9 to make the processor smaller and more power-efficient. Nvidia is now using a variant of Cortex-A9 in its latest Tegra 4i chip with integrated LTE, which was announced a few days ahead of MWC.
