The history of embedded systems is intertwined with the evolution of computing and microelectronics. While the term "embedded system" wasn't widely used until later, the concept dates back to the early days of computing.

• Early Beginnings (1960s): The Apollo Guidance Computer (AGC), used in the Apollo missions, is considered one of the earliest examples of an embedded system. It was a real-time computer that controlled the spacecraft's navigation and guidance systems. Another early example is the Autonetics D-17B guidance computer used in the Minuteman missile.

• The Microprocessor Revolution (1970s): The invention of the microprocessor in the early 1970s by Intel (the 4004) revolutionized embedded systems. Microprocessors made it possible to create smaller, cheaper, and more powerful embedded systems. This led to the development of embedded systems for a wider range of applications, such as industrial control, automotive electronics, and consumer electronics.

• Growth and Diversification (1980s and 1990s): The 1980s and 1990s saw rapid growth and diversification in the field of embedded systems. New microcontrollers with integrated peripherals were developed, making it easier to build complex embedded systems. The rise of the internet also led to the development of networked embedded systems.

• The Rise of the Internet of Things (2000s - Present): The Internet of Things (IoT) has further accelerated the growth of embedded systems. IoT devices are embedded systems that are connected to the internet, allowing them to communicate with each other and with cloud-based services. This has led to the development of new applications for embedded systems in areas such as smart homes, smart cities, and industrial automation.

• Key Milestones:

  • 1960s: Apollo Guidance Computer
