Arm readies processing cores for 64-bit computing

From InfoWorld: Arm Holdings will unveil new plans for processing cores that support 64-bit computing within the next few weeks, and has already shown samples at private viewings, sources close to the company said at an Arm technology conference in Taipei.

The company's move into 64-bit computing shows it's serious about putting out powerful processors to meet the needs of businesses and consumers. Most personal computers today are based on 32-bit computing, while supercomputers, servers, and other bigger systems use 64-bit computing, which can address more memory.

More memory can significantly improve performance for people running a lot of applications at once in just about any device.

Intel, the world's largest chip maker, already offers a number of processors for 64-bit computing,, including for servers, desktops and mobile computers, as does its rival Advanced Micro Devices (AMD).

Intel and AMD both make processors based on the x86 architecture, while Arm's chips are based on an entirely different architecture, meaning that x86 software needs to be rewritten before it will run on Arm processor cores. Arm's processor designs, though, are more often found in mobile devices or embedded systems than in desktop PCs today.
