Most embedded systems are reactive by nature. They measure certain properties of their environment with sensors and react on changes. For example, they display something, move a motor, or send a ...

The interest in state machines started in the 1950s when George Moore and Edward Mealy published seminal papers on formal methods of designing digital circuits, which generate outputs based on the ...

State machines are a foundation of digital design. Eventually we all reach the point where we need to control our digital algorithm, and we almost always turn to a state machine to do the job. State ...

Control systems that manage electrical or mechanical systems mustoften be able to generate, or respond to, sequential events in thesystem. This ability to use time as part of the driver equation is ...
