ARM specs out first 64-bit RISC chips • The Register

With the announcements recently from Calxeda and HP now ARM is jumping back into the limelight. They are working on the next version of the ARM architecture which will feature a 64bit clean design (which some speculated was going to arrive with ARM-15). Although the current version of the ARM architecture and support 40bit data paths, anything wider than that has to be worked around through OS level support of the underlying workaround. In a word, it’s a non-trivial task. But things will get much easier with the next Rev. All hail Version 8
