Comparison of Cortex-M Architectures

	M0	M0+	M1	M3	M4	M7
ARM Architecture	ARMv6-M	ARMv6-M	ARMv6-M	ARMv7-M	ARMv7E-M	ARMv7E-M
Pipeline	3-Stage	2-Stage	3-Stage	3-Stage + branch speculation	3-Stage + branch speculation	6-Stage + branch speculation
Architecture	von Neumann	von Neumann	von Neumann	Harvard	Harvard	Harvard
Functions:	Optimised for physical silicon die size + cost	Superset of M0	Optimized core designed to be loaded into FPGA chips.	All Thumb instructions	Essentially M3 + DSP	High performance, ~2x efficiency of M4
	Supports Thumb-1 and some of Thumb-2	Optional MTB (micro trace buffer)		H/W divide	DSP: MAC + SIMD	Superscaler
		Optional MPU (memory protection unit)		Saturation arithmetic	Optional FPU	64-Bit Instruction + Data buses
				Optional MPU (memory protection unit)	Optional MPU (memory protection unit)
