+As reported in the image above, Portenta X8 features two powerful computing units:
 
-* **NXP® i.MX 8M Mini** Cortex®-A53 quad-core up to 1.8GHz per core + 1x Cortex®-M4 up to 400 MHz. This microprocessor is the one where the Yocto Linux distribution is running together with Docker containers (check [this section](#linux-environment) of this user manual to learn more).
+* **NXP® i.MX 8M Mini** featuring 4x ARM® Cortex®-A53 cores running up to 1.8GHz and 1x ARM® Cortex®-M4 core running up to 400 MHz. This microprocessor hosts the Yocto Linux distribution and supports Docker containers. For more details, refer to [this section](#linux-environment) of the user manual.
 
-* **STMicroelectronics STM32H747XI** dual-core Cortex®-M7 up to 480 MHz + M4 32 bit Arm® MCU up to 240 MHz. This microcontroller is the one where the "Arduino Mbed OS Portenta Boards" Core is running. M4 core is accessible and programmable by the user, while M7 is dedicated to establishing and guaranteeing the communication between i.MX 8M Mini and M4 as well as to manage peripherals through RPC. Check [this section](#arduino-environment) of this user manual to learn more.

-In addition to the above features, Portenta X8 guarantees security over time. A crypto element (i.e. [NXP® SE050C2](https://www.nxp.com/docs/en/data-sheet/SE050-DATASHEET.pdf)) ensures a secure connection at the hardware level and allows the board to be PSA certified from ARM® (click [here](https://www.psacertified.org/products/portenta-x8/) to learn more).

 Moreover, Portenta X8 can be further customized to get a continuously maintained Linux kernel distribution and to keep security at first by Over-The-Air (OTA) device updates and fleet management. In order to activate these features, you need to create an Arduino Cloud for business account including the so-called **Portenta X8 Board Manager**. Portenta X8 Board Manager has been developed together with [Foundries.io](https://foundries.io/) and allows a user to:
