is a benchmark that measures the performance of the
microcontrollers (MCUs) and central processing units (CPUs) used in embedded systems.
This application shows the STM32H745 device Cortex-M7 and Cortex-M4 scores based on
this benchmark.
A simple touch on the screen starts the benchmark simultaneously on both Cortex-M7 and
Cortex-M4 and displays the score on real STM32H745 device giving:
• ~2020 CoreMarks for Cortex-M7
• ~583 CoreMarks for Cortex-M4
Algorithm Conditions:
• CPU frequency: Cortex-M7 @ 400MHZ, Cortex-M4 @ 200MHZ
• Code: Cortex-M7 Flash Bank1, Cortex-M4 Flash Bank2
• RW data: Cortex-M7 in DTCM, Cortex-M4 in D2 domain SRAM
• Cortex-M7 L1-Cache ON, Cortex-M4 ART ON
• Number of iterations: Cortex-M7 25000, Cortex-M4 10000
• Compiler: IAR embedded workbench for ARM 7.80
