Course Goals o o 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. 9/22/2010 Lecture 1 - Introduction 9

Some basic definitions o Microprocessor – a single CPU on a single IC chip. Contains both control and RALU n Does not have on chip memory, timers, or I/O ports o Microcomputer – u. Processor with memory, I/O, timing, control, interfaces, powersupply o RALU – Register/Arithmetic Logic Unit 9/22/2010 Lecture 1 - Introduction 10
