The first modern, realtime embedded computing system was the Apollo guidance computer, first developed in the 1960s by Dr. Charles Stark Draper at the Massachusetts institute of technology for the Apollo program.
The first developed embeded system was designed to collect data automatically and provide mission-critical calculations for the Apollo command module and lunar module.
In year 1971, Intel released the first commercially available microprocessor unit which was known as INTEL 4004. It's an early microprocessor which requires supported chips and external memory.
In 1978, the national engineering Manufacturers association released a standard for programable microntrollers, improving the embedded system design. By early 1980s, memory, input and output system components had been integrated into the same chip as the processor, forming a microntroller.
Since the beginning of the 20th century, microcontroller based embedded system is being added or
incoperated into every aspect of consumer's daily lives, from credit card readers to cellphones, traffic lights, ATM machines, autonomous cars, unmanned ariel vehicles, scientific calculators, CCTV cameras, etc.
We can see that the embedded system of evolving and growing rapidly both on design and market demand. Embeded system generation started from being a simple computer to use in controlling and use in many other complex and automated tasks.
