The first embedded systems emerged with the development of early microprocessors in the late 1960s. These early systems were used in specialized applications, such as space exploration, military systems, and industrial control.
Example: The Apollo Guidance Computer (AGC), used during NASA's Apollo moon missions, is one of the first notable examples of an embedded system. It featured a custom-built processor to control the spacecraftβs guidance and navigation.
Detailed Explanation
In the 1960s to 1970s, technology saw the development of early microprocessors, which are central components in computers. Around this time, the first embedded systems appeared. Unlike general-purpose computers, these systems were designed for specific tasks. For example, the Apollo Guidance Computer was created specifically for space missions. It helped astronauts navigate and control their spacecraft, showcasing the early use of embedded systems in high-stakes environments.
Examples & Analogies
Think of the Apollo Guidance Computer like a specialized tool in a toolbox. Just as you wouldn't use a hammer to screw in a bolt, the computer was tailored solely for the unique needs of space travel, much like how a wrench is designed for a specific purpose.
The Rise of Microcontrollers (1980s)
