The X-CUBE-PERF-H7 firmware aims to demonstrate the performance of the STM32H7x3 architecture with its Cortex®-M7 able to run at 400 MHz, and its instruction and data caches that unleash core performance with 0-wait-state-like execution from different memories, either internal or external, scattered across different domains (D1, D2, and D3) and accessed by the core either through the TCM buses or the AXIM bus.
The firmware is provided with several project configurations for the STM32H743I-EVAL evaluation board. Each project allows the execution of application code and data storage in different memory locations such as internal memories as well as external memories located in different domains (D1, D2 and D3). Firmware results demonstrate that performance is almost the same when internal memories or external memories or different domains are used for code execution or data storage. An FFT use case (provided by the CMSIS library) is proposed as an example with several toolchains: Keil® (MDK-ARM), IAR™ (EWARM), and System Workbench (SW4STM32). It can easily be ported to any other toolchain.

The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
The X-CUBE-VS4A Expansion Package consists of a set of libraries and application examples for STM32F7 Series microcontrollers acting as Alexa-enabled devices. It runs on the 32F769IDISCOVERY board, which provides a native Ethernet interface.
