Architecural Evolution 4 bit internal – 4 bit data bus – 8 bit address 8 bit internal – 8 bit data bus – 16 bit address 16 bit internal – 8 bit data bus – 20 bit address 16 bit internal – 16 bit data bus – 22 bit addr 32 bit internal – 16 bit data bus – 24 bit addr 32 bit internal – 32 bit data bus – 28 bit addr 64 bit internal – 32 bit data bus – 32 bit addr 64 bit internal – 64 bit data bus – 32 bit addr 128 bit internal?????? and the future ????? The evolution will continue

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.

9/22/2010 Lecture 1 - Introduction 10

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
