About ARMv7

The ARMv7 architecture lies below the CortexTM family of processors and defines three distinct processor profiles: the A profile for sophisticated, virtual memory-based OS and user applications; the R profile for real-time systems; and the M profile optimized for microcontroller and low-cost applications.All ARMv7 architecture profiles implement Thumb® -2 technology which is built on the foundation of the ARM industry-leading Thumb code compression technology, while retaining complete code compatibility with existing ARM solutions. The ARMv7 architecture also includes the NEON™ technology extensions to increase DSP and media processing throughput by up to 400 percent, and offers improved floating point support to address the needs of next generation 3D graphics and games physics, as well as traditional embedded control applications.
