Arm Evolution Changes:
ARM Classic: ARM7,ARM9,ARM11 performance in turn.
Cortex:
M Series: Cortex-m0,cortex-m1,cortex-m2,cortex-m3,cortex-m4 used in industrial control field (no operating system) analogy single-chip microcomputer performance than monolithic microcomputer strong.
R Series: Cortex-r4 for real-time applications, you can run the operating system.
A series: Cortex-a5,cortex-a8,cortex-a9 mainly for multimedia applications, modern smartphones basically use the CORTEX-A series. The M,r,a series also improves performance.
Its performance comparison: ARM7 and cortex-m3 basically similar to the latter is more advanced. The AM9,ARM11 is basically located between the CORTEX-R4 and Cortex-a5 areas and has a distance from CORTEX-A5.
