1.3. Compliance

The Cortex-A9 processor implements the ARMv7-A architecture that includes the following features:

  • ARM Thumb®-2 32-bit instruction set architecture for overall code density comparable with Thumb and performance comparable with ARM instructions. See the ARM Architecture Reference Manual for information on both the ARM and Thumb instruction sets.

  • Thumb Execution Environment (ThumbEE) architecture for execution environment acceleration. See the ARM Architecture Reference Manual for information on the ThumbEE instruction set.

  • Security Extensions for enhanced security. See the ARM Architecture Reference Manual for information on Security Extensions..

  • Advanced SIMD architecture extension to accelerate the performance of multimedia applications such as 3-D graphics and image processing. See the ARM Architecture Reference Manual for information on the Advanced SIMD architecture extension .

    See the Cortex-A9 NEON Media Processing Engine Technical Reference Manual for implementation-specific information.

  • Vector Floating-Point version 3 (VFPv3) architecture extension for floating-point computation that is fully compliant with the IEEE 754 standard. See the ARM Architecture Reference Manual for information on the VFPv3 extension.

    See the Cortex-A9 Floating-Point Unit Technical Reference Manual for implementation-specific information.

  • ARMv7 Debug architecture that includes support for Security Extensions and CoreSight. See the ARM Architecture Reference Manual for information on the ARMv7 Debug architecture.
