Where did you get this ''MISP test''?

To jrnore,

Did you try with ARM or IAR compiler?

May be you will get 1.25 DMIPS/Mhz

Hi all,

In 2010,a New STM32F2xx will be available with zero-wait program execution up to 120MHz :

For unique performance benefiting from the 90nm process and the ART memory accelerator have been verified according to CoreMark™ tests created by the Embedded Microprocessor Benchmark Consortium. CoreMark results verify the STM32 executes 8% faster than Cortex-M competitors at 100MHz clock speed. The performance advantage is greater still at 120MHz. CoreMark analysis also confirms dynamic power consumption of only 188µA/MHz (98µA/CoreMark). This is equivalent to drawing 5mA at 120MHz (executing from Flash memory, with ART accelerator enabled and all peripherals off).

Continue releasing your Creativity

In worst cases, the critical code can run in RAM with 0 waitstate.
