How Apple’s A7 64-bit chip gives iOS plenty of headroom for the future

<p>Much has been made of Apple's A7 processor's 64-bit support, and if it's built around ARM's latest architecture as that seems to imply, then there's a lot there's a lot more to the next generation Apple processor than we're seeing.</p><p>Because when you drill down into the silicon, ARM's v8 architecture does a lot more than just increasing the addressable memory.Apple's latest silicon: more than meets the iOS?</p><p>Perhaps the most significant change in ARMv8 is support for Type-1 hypervisors something that's essential as it uses a virtual machine to run 32-bit code.</p><p>Like Intel's and AMD's x64 processors, a Type-1 Hypervisor lets you run virtual machines directly on the silicon, with separate partitions for each VM and no need for resource-hogging emulation layers. There's also support for common cryptographic algorithms in silicon, with instruction set calls that speed up access to the functions needed to deliver secure encrypted file systems.</p><p><a href="http://www.zdnet.com/how-apples-a7-64-bit-chip-gives-ios-plenty-of-headroom-for-the-future-7000020686/">Keep reading...</a></p>
