Raspberry Pi OS is a Unix-like operating system based on the Debian Linux distribution for the Raspberry Pi family of compact single-board computers. Raspbian was developed independently in 2012, became the primary operating system for these boards since 2013, was originally optimized for the Raspberry Pi 1 and distributed by the Raspberry Pi Foundation.

Armbian is a computing build framework that allows users to create system images with configurations for various single-board computers (SBCs). [2] Armbian's objective is to unify the experience across ARM single-board computers, while maintaining performance with hardware-specific optimizations.

The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011. [1] Overview
Most chips support the 32-bit ARMv7-A for legacy applications. All chips of this type have a floating-point unit (FPU) that is better than the one in older ARMv7-A and NEON chips. Some of these chips have coprocessors also include cores from the older 32-bit architecture (ARMv7).
Typically, a rich operating system is run in the less trusted world, with smaller security-specialised code in the more trusted world, aiming to reduce the attack surface. Typical applications include DRM functionality for controlling the use of media on ARM-based devices, [147] and preventing any unapproved use of the device.
