Introduction to Embedded Microcomputer Systems Lecture 1.1 Jonathan W. Valvano EE319K Introduction to Embedded Systems • Course description • Introduce embedded microcomputer systems, • Flowcharts, • Data flow graphs, • Call graphs. Three good data sheets to have available http://users.ece.utexas.edu/~valvano/Datasheets/CPU12rg.pdf http://users.ece.utexas.edu/~valvano/Datasheets/S12CPUV2.pdf http://users.ece.utexas.edu/~valvano/Datasheets/MC9S12DP512.zip An embedded computer system includes a microcomputer mechanical, chemical and electrical devices specific dedicated purpose, and packaged up as a complete system. • communications, • automotive, • military, • medical, • consumer, • machine control. Each embedded microcomputer system accepts inputs, performs calculations, and generates outputs runs in “real time.” In a real time system , upper bound on the time required to perform the input/calculation/output respond to external events Because of the real time nature of these systems, we will study the rich set of features built into these microcontrollers to handle all aspects of time. 1.2. Attitude clients coworkers Test it now. Plan for testing. Get help. There is just no simple way to get to the moon. Use our creativity to break a complex problem into simple components, rather than developing complex solutions to simple problems. 1.3. Components of an embedded system embedded "hidden inside so one can’t see it." computer processor
