Embedded Systems (ES) is a platform that integrates multiple hardware and software components into IC technology for application-specific or application-to-application communication purposes. The overall design of an embedded system depends primarily on the programming part of the IC.
Dr. Charles Stark Draper developed the first embedded system called the Apollo Guidance Computer in 1980. He designed this embedded system to automatically retrieve output calculations based on the system’s mission-critical calculations.
