Benchmarks for STM32H7 MCUs


This work has been supported by WAKeMeUP project accepted for funding within the ECSEL Joint Undertaking in collaboration with the European Union's H2020 Framework Programme (H2020/2014-2020) under grant agreement No. 783176 and Czech National Funding Authority under the grant agreement No. 8A18001.

The application note and evaluation package presents benchmarks developed by UTIA to evaluate the maturity of the 40nm STM32 devices with eFLASH.

Benchmark projects released in the evaluation package for the AC6 System Workbench for STM32 are developed by UTIA as modification of the STMicroelectronics STM32Cube_FW_F7_V1.15.0 and STM32Cube_FW_H7_V1.5.0 reference SW projects.

Benchmarks document performance increase of the 40nm STM32H7 devices with eFLASH in comparison to the 90 nm STM32F7 devices with eFLASH.

Matrix multiplication on STM32756G_EVAL

Matrix multiplication on NUCLEO-H755ZI on CM7 and CM4 MCU

We use NUCLEO-H755ZI board with two MCUs, the 400 MHz CM7 MCU and the 200 MHz CM4 MCU on 40 nm CMOS device with 2MB eFLASH. We also use the NUCLEO-H753ZI board with single 400 MHz CM7 MCU on 40 nm CMOS device with 2MB eFLASH.

The benchmark projects developed for STM32756G_EVAL board serve for the comparison with the reference 216 MHz CM7 MCU 90nm CMOS device. All benchmark projects developed for NUCLEO-H755ZI and NUCLEO-H753ZI support the Adaruit 1.8'' colour TFT 128x160 pixel display V2 and optionally the older version of the Adafruit TFT display V1.
