ARM and Samsung putting final touches on a 64-bit Exynos, 128-bit mobile chips fleshed out, too
The CPU should belong to Samsung's Exynos family, and is likely planned as a direct response to the 64-bit Apple A7 chipset, as found in the iPhone 5s and the new iPads. “Executives from Samsung and ARM had a meeting today. They discussed the ARM 64-bit chip, which is expected to be used in Samsung’s smartphone next year,” were the senior manager's exact words.
Cortex-M processors, for devices such as a smart home system, have been discussed during the meeting as well, where ARM’s executive vice president of commercial and global development, Antonio Viana, has allegedly been present. The insider also noted that 128-bit processors are being bandied about at ARM as a possibility, but not until two years from now.
