1.2 About the architecture
The processor implements the ARMv7-R architecture and ARMv7 debug architecture. In
addition, the Cortex-R4F processor implements the VFPv3-D16 architecture. This includes the
VFPv3 instruction set.
The ARMv7-R architecture provides 32-bit ARM and 16-bit and 32-bit Thumb instruction sets,
including a range of Single Instruction, Multiple-Data (SIMD) Digital Signal Processing (DSP)
instructions that operate on 16-bit or 8-bit data values in 32-bit registers.
See the ARM Architecture Reference Manual, ARMv7-A and ARMv7-R edition for more
information on the:
• ARM instruction set and Thumb instruction set
• ARMv7 debug architecture
• VFPv3 instruction set.
