  • Memory constraints in the read-only memory (ROM) and random access memory (RAM) add to the complexity of development

What Are the Key Components of Embedded Systems?

Embedded systems operate when software and hardware interact with each other. For example, embedded Linux is a tailored operating system version of Linux OS.

However, embedded systems have key components in two layers: hardware and software. Let’s understand the key differences between hardware and software layers.

Hardware Layer in Embedded Systems

The hardware layer in embedded systems in a particular device comprises the following components:

  • CPU – A central processing unit to receive data from the software and process set responses.
  • Power Supply – Hardware to help the system on chip charge via battery or electrical plug.
  • RAM or ROM Memory – The random access memory and read-only memory capabilities hardware.
  • Timers – Hardware to guide a smart home system to switch the lights off at a specified time.
  • User Interface – A set of buttons, features, and actions available to device users.

Also, the hardware surface has communication ports used to communicate with other computers or systems, including:

  • A universal serial bus (USB) drive
  • Controller area network (CAN)
  • Firewire
  • Inter-integrated circuit (I2C)
  • SAE J1587/J1708
  • Serial peripherals interface (SPI)
  • Universal asynchronous receiver/transmitter (UART)

Software Layer in Embedded Systems

The software layer in embedded systems in various devices comprises the following:

  • Application Software – Applications that run exclusively in real-time operating systems.
  • Device Drivers – Facilitates specific hardware-software communication and seamless functions.
  • Firmware – Controls booting processes, hardware interface maintenance, and low-level operations.
  • Machine Learning Code – Machine-generated code with programming languages like C and C++.
  • Real-Time Operating Systems – Schedules and manages tasks, and executes vital operations.
  • Middleware – Middleware handles the complexity of inter-component communication.

Types of Embedded Software Tools

An embedded system charges the software development industry but has a few tools to help. Here are the most common examples of embedded software tools embedded software developers use:

  • AI Code Generation Tools – Artificial intelligence generates code from high-level specifications.
  • Assembly Tools – Assembles code that was written in an assembly language.
  • Code Editing Tools – Specifically creates code with C and C++ programming languages.
  • Cross-Compiler – Allows code to be built on one platform and integrated into other devices.
  • Debuggers – Has features to find and fix bugs in code for efficient execution.
  • Linker Tool – Combines written code modules or pieces to design executable programming.
  • Simulators or Emulators – Let engineers test and repair bugs without host computers.
  • System Configuration – Technology to automate code generation to reduce manual errors.

Alternatively, embedded software engineering uses integrated development environments (IDE) with modules for debugging, cross-compiling, and code editing in one environment.

Software Engineering Embedded Software Development Process

The embedded software development process often follows different modules, including a typical SDLC. Read more about the software development life cycle (SDLC) here.

Embedded Software Development Process

However, let’s see the phases of an embedded software development project in software engineering.

Step 1: Define Embedded Software Project Scope

Start with a goal to define the embedded software project scope. Determine the applications for which the system is intended to discover the project goals and outline a scope.

Delivering an embedded systems range or scope created by an embedded software engineer involves adding the key feature range, cloud collaborations, and methods to connect controlling software.

Embedded software engineering is about controlling and outlining every output, result, piece required, application variety, highlighting the purposes, specific intricacies, and details of the project.

Step 2: Gather and Analyse Specifications Requirements

Requirements engineering is instrumental in every development process. The benefit of using our Requiment requirements gathering and analysis tool is that you automate a lot of the process.

Step 3: Choose the Right Hardware Components and Platforms

The right platforms, devices, and hardware are essential to an embedded system or operating system working in real-time environments, especially on multiple devices.

Consider processors, memory, communication, user interface, specific chips chosen, and battery for system charges. Also, choose platforms with support from a robust development ecosystem.

Step 4: Design the Architecture

Use state-machine, event-driven, or layered architecture modules to design a system’s backbone for performance and precise configuration for simpler devices and other systems.

Software architecture on IoT devices and other programs, even a traditional calculator, follows a similar principle. An embedded system enables a single function to manage all interactions in the system. Embedded software engineers create or design the program architecture for that purpose.

Step 5: Firmware Coding

Use the most common languages to create an embedded software program, including C, C++, Java, and Python to create the code and environmental conditions. The power lies in how you write the code.

Developing embedded software with an embedded software engineer in embedded software engineering carries expected innovation, efficiency, focus, and specialist skills to write code.

Step 6: Communication Interface Implementation

Integrate the right communication interface for remote control and data interchange when creating embedded systems. Wired options for creating communication interfaces include UART, SPI, and I2C, while wireless options include Wi-Fi and Bluetooth.

Step 7: Embedded Testing and Debugging

Scheduling a task for reliability and security testing is pivotal to the embedded system’s success in various domains and on multiple IoT devices. Debugging and tests can also display potential risks and the ability for future company improvements.

Also, this step leads to identifying external factors and environmental factors to consider in security, including face identification authentication, setting rules and protocols, and user functionality control.

Step 8: Embedded System Integration and Deployment

Finally, embedded integration is the final step. Embedded software engineers integrate the hardware and software into a final system that functions for user applications in deployment.

The foundation of quality-defining speed in software engineering and other embedded systems in a real-time operating system (OS) lies in the expected responsibilities of an embedded software engineer.

Software engineering also oversees the deployment of system functionality, control protocols, operation inputs, and how the software will perform with a specified user input.
