ARM on Thursday outlined some of the details of its first 64-bit chip architecture, ARMv8. The design is an extension of the current 32-bit ARMv7 and either keeps or expands on features like its Neon instructions, security, and virtual machine support. Most of the benefit comes from the move to 64-bit by itself, which lets it handle much larger data sets and support more virtual memory, sometimes leading to faster performance.
Its 32-bit component keeps all the same features and is backwards compatible. An OS could theoretically build in support for legacy apps, although ARM hasn't said if the v8 platform supports running 32- and 64-bit code at the same time. »read more
