Here is a bit from the ST datasheet for my chip. 300 MHz Cortex-M7chips are available now. My old cheap STM32F746ZG runs at 216 MHz so much more speed is possible. Exports to OrCAD, Allegro, Altium, PADS, Eagle, KiCad, Diptrace & Pulsonix. STM32F746ZG, mbed-Enabled Development Nucleo-144 STM32F7 ARM® Cortex®-M7 MCU 32-Bit Embedded Evaluation Board. The increase in instructions per cycle have led to a modest improvement in clock rate, says York, for twice the number of instructions per cycle.Ĭortex M-7 is designed to run at up to 800 MHz with 28nm features.

The six-stage pipeline delivers a performance of 2.14DMIPS/MHz, improving the Cortex-M4’s 1.25DIPS/MHz, to fulfil the capability requirements that are normally only seen at the high end of the market. The Cortex-M7’s superscalar pipeline allows the processor to execute more instructions/second. The ARMv7E M six-stage pipeline architecture increases throughput compared to the Cortex-M4 which uses the three-stage pipeline ARMv7E M architecture with the Thumb/Thumb 2 instruction set. To do this you must go into the code for the configurator and manually change the multipliers. This is where most of the speed-up comes from. 1 The clock configurator in STM32CubeMX does not allow the PLL divider DIVP1 frequency to exceed 300MHz so it is impossible to use it to achieve the boards maximum of 480MHz. "The Cortex-M4 can execute just one instruction at one time. "The Cortex-M7 has a superscalar pipeline which can execute two instructions simultaneously," an ARM source told us I am still looking at the architecture but this is what I read in some popular articles. Cortex-M7 can "execute two instructions per cycle".
