Why bother with 64-bit mobile chips?Even if 64-bit computing isn't some across-the-board speedup technology, there's a very good reason to adopt it: the future. But here again, we have to splash a little cold water on Schiller's enthusiasm. "The PC world went through the transition from 32-bit to 64-bit, and it took years," Schiller said. "Today you're going to see that Apple is going to move the mobile computing system forward from 32-bit to 64-bit in one day."Sure, it only took a couple hours for Apple to announce the iPhone 5S and the A7 processor. But the full 64-bit transition will take years in mobile, just as it did in the PC market.

Indeed, the transition already has been going on for a couple years, In 2011, after four years of behind-closed-doors work, ARM Holdings announced its 64-bit ARMv8 instruction set for the chip designs it licenses to Apple, Qualcomm, Samsung, and many other makers of mobile chips, Apple's A7 uses the ARMv8 architecture, The hardware change is only the first part, After that comes software, Apple has retooled iOS 7 -- the kernel at the strongfit designers series case for apple iphone 6 and 6s - watercolor summer flowers heart of the software, the libraries of prewritten code that it and other software draw upon, and the device drivers the kernel uses to talk to hardware like the network and touch screen -- so that it's 64-bit software, And it's got a version of its Xcode developer tools so that programmers can build 64-bit versions of their iOS products..

But it'll be years before the whole software ecosystem makes the move. Old software likely will never make the change, which is why it's good ARMv8 chips can run older 32-bit software seamlessly. And programmers will still need to build 32-bit versions of their software for older iPhones -- as well as brand-new 32-bit models like the iPhone 5C. Given how long it takes to make the transition, it's important to lay the hardware foundation early enough that the software market can move gracefully. Even though adding more RAM is hard in mobile devices, it'll happen. It might well happen sooner on iPads, too, which can handle faster processors, bigger batteries, and more elaborate software. And it's possible that computing engineers will successfully commercialize some other form of memory that's not as power-hungry.

ARMv8 benefitsA nearer-term reason the Apple A7 might appeal to programmers has nothing to do with its 64-bit nature: the ARMv8 architecture itself brings some real advantages, One of them is a larger number of registers -- tiny on-chip storage areas where the processor stores data for very fast access, ARMv8 roughly doubles general-purpose registers from 16 to 31, which means the chip needn't fritter away as many cycles swapping things into and strongfit designers series case for apple iphone 6 and 6s - watercolor summer flowers out of memory, When AMD pioneered 64-bit computing on x86 -- a transition it pushed while Intel was distracted with its Itanium designs -- it got a big speed boost from increasing the number of registers, But 32-bit x86 chips were hobbled by having only four registers, while 32-bit ARM chips have a relatively abundant 16; that could mean the performance boost won't be as good with the ARM transition..

ARMv8 also has some other significant changes. It's got much better mathematical abilities, especially when performing the same operation on a lot of data. And it's got built-in encryption processing abilities, which should speed a lot of secure communications and cut battery usage. New Apple optionsApple surprised the world when it moved its Mac line from PowerPC processors to Intel processors, and there have been rumblings it might move to or at least embrace ARM chips for Macs, too. The A7 processor or its rumored higher-end A7X sibling might not have enough oomph for a full-fledged personal computer, but it was hard to miss Schiller boasting that the A7 has a "desktop-class architecture." And even if there's never any ARM-based Mac, it's still possible Apple could take iOS into something more laptop-like. The company, which made iWork free with new iOS devices and threw iPhoto and iMovie into the bargain, clearly likes the idea of customers creating content on iOS devices, not just consuming it.
