2.1. About the programmers model

This section describes the processor at the level required to write functional code. It does not include internal microarchitecture details.

The processor implements the ARMv7-A architecture. This includes:

  • the 32-bit ARM instruction set

  • the 16-bit and 32-bit Thumb-2 instruction set

  • the ThumbEE instruction set

  • the Security Extensions architecture

  • the Advanced SIMD architecture.

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