Intelligent Cruise-Control Applications: Real-Time, Embedded Hybrid Control Software

摘要

Real-time embedded systems have become prevalent in our everyday life. Cell phones, PDAs,televisions, washing machines, microwave ovens, and calculators all contain embedded processors. An embedded system is a special-purpose computer system built into a larger device [3]. Since many embedded systems are produced in the tens-of-thousands-to millions-of-units range, reducing cost is a major concern. Embedded systems often use a (relatively) slow processor clock speed and small memory size to cut costs. Programs on an embedded system often must run with real-time constraints; i.e., a late answer is considered a wrong answer. Often there is no disk drive, operating system, keyboard, or screen.
