产品概述
描述
The X-CUBE-PERF-H7 Expansion Package aims to demonstrate the performance of the STM32H74x and STM32H75x architecture with its Arm® Cortex®‑M7 single core able to run at up to 480 MHz. The core instruction and data caches unleash its performance with 0-wait-state-like execution from different memories. The memories can be either internal or external, scattered across different domains (D1, D2, and D3), and accessed by the core through the TCM buses or the AXIM bus.
The Expansion Package 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 similar when the code execution or data storage uses internal or external memories located in different domains. An FFT use case (provided by the CMSIS library) is proposed as an example with several toolchains: Keil® (MDK-ARM), IAR Systems® (EWARM), and STMicroelectronics System Workbench (SW4STM32). It can be ported easily to any other toolchain and any STM32H7 Series single-core device.
The generic microcontroller names STM32H74x and STM32H75x represent the STM32H7 Series single-core devices in the following product lines: STM32H742, STM32H743/753, and STM32H750 Value line.

Follow issues and share solutions on Github for STM32Cube MCU packages. Integrate your own software components in a STM32Cube Expansion for STM32CubeMX and STM32CubeIDE tools, thanks to the new STM32PackCreator utility
STM32CubeMX is part of the STM32Cube initiative designed to simplify and accelerate the development of applications for STM32 microcontrollers. STM32CubeMX offers the possibility to generate C projects using embedded software offers packages like CMSIS-Pack compliant software packs. Starting with the 6.0.0 revision, STM32CubeMX is delivered with STM32PackCreator, an STM32 pack creation graphical companion tool, whose main purpose is the creation of software packs.
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.
