9. 9/22/2010Lecture 1 - Introduction9 Course Goals  Understand more advanced micro-computer architecture concepts through the study of a representative architecture.  The 68000 family is one of several microprocessor families available. It has a relatively simple instruction set and representative interfacing capabilities. It also supports multitasking.

10. 9/22/2010Lecture 1 - Introduction10 Some basic definitions  Microprocessor – a single CPU on a single IC chip. Contains both control and RALU Does not have on chip memory, timers, or I/O ports  Microcomputer – uProcessor with memory, I/O, timing, control, interfaces, powersupply  Microcontroller – has the elements of a microprocessor with supporting memory, I/O, timers, clock, interfaces (such as A-to-D) on board.  RALU – Register/Arithmetic Logic Unit
