Cortexâ„¢-A8 Technical Reference Manual 1.2.Â ARMv7-A architecture

1.2.Â ARMv7-A architecture

The processor implements ARMv7-A that includes the following features:

ARM Thumb^Â®-2 instruction set for overall code density comparable with Thumb and performance comparable with ARM instructions.
Thumb Execution Environment (ThumbEE) to provide execution environment acceleration.
Security Extensions architecture for enhanced security features that facilitate the development of secure applications.
Advanced SIMD architecture extension to accelerate the performance of multimedia applications such as 3-D graphics and image processing.
Note
The Advanced SIMD architecture extension, its associated implementations, and supporting software, are commonly referred to as NEON technology.
Vector Floating Point v3 (VFPv3) architecture for floating-point computation that is fully compliant with the IEEE 754 standard.

See the ARM Architecture Reference Manual for more information on the ARMv7-A architecture.
