1.2. ARMv7-A architecture

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

  • ARM Thumb®-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.

    • This document uses the older assembler language instruction mnemonics. See Appendix B Instruction Mnemonics for information about the Unified Assembler Language (UAL) equivalents of the Advanced SIMD instruction mnemonics. See the ARM Architecture Reference Manual for more information on the UAL syntax.

  • Vector Floating Point v3 (VFPv3) architecture for floating-point computation that is fully compliant with the IEEE 754 standard.

    Note

    This document uses the older assembler language instruction mnemonics. See Appendix B Instruction Mnemonics for information about the Unified Assembler Language (UAL) equivalents of the VFP data-processing instruction mnemonics. See the ARM Architecture Reference Manual for more information on the UAL syntax.
