== Extending the STM32 MCU family to the MPU world ==<br />
'''Microcontroller units (MCUs)''' are built around MMU-less cores such as the Arm Cortex-M, which are very efficient for deterministic operations in a bare metal or real time operating system (RTOS) context. STMicroelectronics STM32 MCUs embed enough SRAM (static RAM) and Flash memory for many applications, and this can be completed with external memories.<br /><br />
<br />
'''Microprocessor units (MPUs)''' rely on cores such as the Arm Cortex-A, with memory management unit (MMU) to manage virtual memory spaces, opening the door to efficient support of a rich operating system (OS) such as Linux. A fast interconnect makes the bridge between the processing unit, high-bandwidth peripherals, external memories (RAM and NVM) and, usually, a graphical Processing Unit (GPU).<br /><br />
<br />
'''STMicroelectronics has a strong presence in MCU markets with STM32 family''' <ref>http://www.st.com/en/microcontrollers/stm32-32-bit-arm-cortex-mcus.html</ref> and entered the MPU market with a first platform referenced as [[STM32MP15 microprocessor|'''STM32MP15''']]. This platform aims to address multiple market segments such as industrial, consumer, healthcare, home and building automation.<br /><br />
<br />
The STMicroelectronics approach for a smooth transition to the MPU world consists of putting both worlds in a single device, seeing the MCU as a subsystem of the MPU:<br />
{{ProductMarketingReviewsComments| JLD : Today: The overall introduction is perfect. My comment relates to this last sentence. Even if true on the technical perscpective, I would tend to remove it for marketing perspective. I would replace by:<br />
The new markets STMicro targets require more power and more flexibility which can be easily leveraged thanks to the OpenOS environment ported onto the cortexA cores. or some thing like this..Seen from another angle: the previous sentence is very market minded while the last one si more technical..}}<br />

}}<br />
<br />
As seen above, the MPU is a multiple-core architecture that can interact with a wide number of peripherals. Some '''new concepts''' need to be introduced for a good understanding of the system: these concepts are explained below and are illustrated in the figure on the right.<br />
<br />
===Hardware execution contexts===<br />
Each core can run in a non-secure and - eventually - a secure (Arm Trustzone<ref>https://www.arm.com/products/security-on-arm/trustzone</ref>) mode. <br /><br />
A '''hardware execution context''' corresponds to a core and security mode.<br /><br />
The three hardware execution contexts available on STM32 MPU devices are:<br />
<br />
* <span style="color:#FFFFFF; background:#D4007A">&nbsp;Arm Cortex-A secure&nbsp;</span> (Trustzone)<br />
* <span style="color:#FFFFFF; background:#002052">&nbsp;Arm Cortex-A non secure&nbsp;</span><br />
* <span style="color:#FFFFFF; background:#39A9DC">&nbsp;Arm Cortex-M&nbsp;</span> (non-secure)<br />
<br />
Each hardware execution context can host different firmware, depending on the platform state. The following contexts can be distinguished:<br />
* the '''boot time''' context, corresponding to a transitory firmware execution, when the device is booting up<br />
* the '''runtime''' context, corresponding to an established firmware execution, when the device is up-and-running<br />
<br />
===Firmwares executed in the runtime contexts===<br />
Each runtime context executes a given piece of '''firmware''':<br />
* <span style="color:#FFFFFF; background:#D4007A">&nbsp;Arm Cortex-A secure&nbsp;</span> (Trustzone), executes '''OP-TEE'''<ref name="STM32MPU ES">[[STM32MPU_Embedded_Software_architecture_overview|STM32MPU Embedded Software]]</ref><br />
* <span style="color:#FFFFFF; background:#002052">&nbsp;Arm Cortex-A non secure&nbsp;</span>, executes '''Linux'''<ref name="STM32MPU ES"/><br />
* <span style="color:#FFFFFF; background:#39A9DC">&nbsp;Arm Cortex-M&nbsp;</span> (non-secure), executes '''STM32Cube'''<ref name="STM32MPU ES"/><br />
OP-TEE, Linux and STM32Cube are '''STM32MPU Embedded Software'''<ref name="STM32MPU ES"/> components.<br />
<br />
===Peripheral assignment to the runtime contexts===<br />
The term '''peripheral assignment''' is used to identify the action to assign a set of peripherals to a runtime context. This is a user choice that can be realized via STM32CubeMX<ref>[[STM32CubeMX]]</ref> or manually, in order to properly configure the boot chain<ref>[[Boot_chains_overview]]</ref> and the several pieces of firmware that run on the platform.<br />
<br />
Each microprocessor peripheral-overview article shows the assignment capabilities for each peripheral, with a table similar to the example below:<br />
