Linux Learning Summary 1--linux embedded real-time application development practical

What is an embedded system? The mobile phone is a typical embedded system.

Embedded computers are used much more than PCs. In fact, recent market data show that the microprocessor chip used by personal computers accounts for only 2% of the annual market share. The average room has at least dozens of embedded computers, even without a personal computer.

What is real-time? The correctness of real-time system processing not only requires the correct logic of processing, but also requires the result in a specified time period. If the system's time constraints cannot be met, then the system will fail.

Open source means that the software should be freely available for use, modification, and reproduction.
