ARM has the first details released of its new ARMv8-A processor architecture. The new architecture is the first ARM with 64bit support and is fully compatible with the current ARMv7-A architecture.
The two main execution states of the new ARMv8-a architecture, AArch64 and AArch32. The first introduces the new 64bit-A64 instruction set, while the second provides support for the current A32 – Thumb-2-32bit-instruction sets. Parts of the current ARMv7 architecture Trustzone, virtualization and Neon have been retained or extended in the ARMv8.
The A64 instruction set does include 64bit-processing of data, and 64bit addressing of virtual memory. This allows energy-efficient chips based on the new architecture be used for more data centers, other responsibilities, and supercomputers, where energy consumption and hitteafgifte of the hot items are.
The-up chip designer wants to get an ecosystem around the new 64bit instruction set to build. Key partners of the company have, therefore, of the-up chip designer all of the ARM compiler with ARMv8 support, while getting started with the support of the new architecture in the open-source operating systems, applications, and development tools.
The specification of ARMv8, in which all aspects of the architecture are described, is now already available for partners to license agreements are closed. ARM makes the first processorontwerpen based on ARMv8 in 2012, while the first prototypes of servers on the basis of this processorontwerpen in 2014 will be shown.
