EE382C Embedded Software Systems
Block Diagrams (Part 2)

Announcements

• Why bother learning Unix as an implementation platform? Linux. Linux is used in racked-mounted embedded systems and on embedded processors (e.g. TI TMS320C6000).
• Bjarne Stroustrup, "Speaking C++ as a Native", Wednesday, February 25, 2004, 6:30 PM, IBM, Bldg. 908, 11400 Burnet Rd, Austin, TX 78758.

Lecture

• Lecture on Block Diagrams (Part 2) as slides 13-32 of "Block Diagrams for Modeling and Design" by Prof. Edward A. Lee at UC Berkeley
  • Synchronous/reactive systems and fixed-point computation
  • Run-time error from a well-specified synchronous/reactive system: output of A goes to B and B feeds back to A, where B is an inverter and A is an identity system. Here, you have an inverter driving itself, which is a contradiction.
  • Reactive vs. Synchronous
