Why Use MPU in RTOS Systems?

First, let me clarify that MPU has many meanings, and there are two common ones:

MPU:Memory Protection Unit;
MPU:Microprocessor Unit;

Additionally, some may associate it with modules like MPU-6050. So, please do not confuse MPU.

Why Use MPU?

If you develop embedded projects that suffer significant economic losses or major accidents due to memory overflow or memory faults, you will understand why a Memory Protection Unit (MPU) is necessary.

Using an MPU in embedded systems can help detect memory-related bugs early in development, saving more time.

Moreover,

Lightweight Embedded System Framework: mr-library Overview

Introduction to mr-library

mr-library is a lightweight framework for embedded systems that provides a unified low-level driver device model and basic service functions. It features modular design, configurability, and extensibility, helping developers quickly build embedded applications.

The mr-library framework supports basic kernel functions such as mutexes and object management. It integrates asynchronous event-driven frameworks (events), multi-timer software timers (soft-timer), and other services. It provides driver device models for common peripherals such as serial ports, SPI, I2C, ADC/DAC, allowing access to underlying hardware

Embedded System Architecture Design

1. Embedded Systems
Components of Embedded Systems:Generally, embedded systems consist of embedded processors, supporting hardware, embedded operating systems, supporting software, and application software.
Embedded systems should have the following characteristics:
◆Strong specificity.Embedded systems are designed for specific application needs, integrating many tasks usually performed by general-purpose CPUs into the chip, which is conducive to miniaturization.
◆Technological integration.Embedded systems combine advanced computing, communication, semiconductor, and electronic technologies with specific applications in various industries, making it a technology-intensive, capital-intensive,
