ARM introduces new architecture

ARM has disclosed the technical details of its new ARMv8 architecture, the first ARM architecture to include a 64-bit instruction set.
Building on the 32-bit ARM architecture, the new ARMv8 architecture will expand the reach of ARM processor-based solutions into consumer and enterprise applications where extended virtual addressing and 64-bit data processing are required, the company said.

“With our increasingly connected world, the market for 32-bit processing continues to expand and evolve creating new opportunities for 32-bit ARMv7 based processors in embedded, real-time and open application platforms.” said Mike Muller, CTO, ARM.

“We believe the ARMv8 architecture is ideally suited to enable the ARM partnership to continue to grow in 32-bit application spaces and bring diverse, innovative and energy-efficient solutions to 64-bit processing markets".

The new architecture consists of two main execution states, AArch64 and AArch32. The AArch64 execution state introduces a new instruction set, A64 for 64-bit processing. The AArch32 state supports the existing ARM instruction set. The key features of the current ARMv7 architecture, including TrustZone, virtualization and NEON advanced SIMD, are maintained or extended in the ARMv8 architecture.
