Embedded System Architecture

In the image above, the concept of embedded systems is explained. Embedded systems are the integration of hardware and software. Let’s delve into this further.

Hardware (H/W)

In embedded systems, hardware refers to the combination of electrical and electronic components, including the processor. The processor itself embodies both hardware and software functionalities. It’s an integrated circuit (IC) designed by hardware engineers, capable of executing programs or software stored in memory.

Different components of Processor hardware:

Software (S/W)

Software (S/W) refers to a collection of instructions, programs, or data that directs a computer or embedded system on how to perform specific tasks or operations. It encompasses applications, operating systems, utilities, and other programs that enable the functionality of hardware devices and systems.

Different components of Software used in Embedded Systems are explained below:

Application

The Application layer represents the high-level software designed to perform specific tasks for the user. This could be anything from a simple user interface to complex data processing algorithms. Applications are what users interact with directly, making them crucial for the system’s functionality.

Middleware

Middleware acts as a bridge between the application and the operating system. It provides common services and capabilities to applications, enabling them to communicate with each other or with the hardware. Middleware simplifies the development process by offering reusable functions, such as data management, messaging, and authentication.

Operating System

The Operating System (OS) is the backbone of the software stack. It manages hardware resources and provides essential services for application software. The OS handles tasks like memory management, process scheduling, and input/output operations, ensuring that applications run smoothly and efficiently.

Device Drivers

Device Drivers serve as the interface between the operating system and hardware peripherals. They translate high-level commands from the OS into low-level commands that the hardware can understand. This allows the OS to control and communicate with various hardware components, such as printers, keyboards, and storage devices.
