Course Goals Understand more advanced micro-computer

architecture concepts through the study of a representative architecture.

Previous = 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.

Now = The ARM architecture

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

Another Example General purpose personal computer

The ARM architecture The text focuses around a SOC based on a

microprocessor core and in designing the core itself. Why is a modern processor designed the way it is?

ARM 26 April 1985 – first ARM prototypes arrive at Acorn

Computers Limited in Cambridge, England. Chips were fabricated by VLIS Technology, Inc. in San Jose, Ca.

A few hours after arrival they were running code. A bottle of bubbly was opened for the celebration. For the remainder of the 80s, ARM was quietly developed to underpin Acorn’s desktop products which formed the basic of educational computing in the UK.

Over the 90s, ARM advanced onto the world stage and established a market leading position in high performance embedded applications.

USE today All cell phones have multiple ARM processor

chips in them. All vehicles have multiple ARM processors in

them.

This class Students will form into groups of 3. Each group of 3 will make multiple presentation

over the semester. By Wednesday of week 1 a list of presentation

topics for week 2 will be set up. Each day 2 groups will make a 15 to 20 minute

presentation of the topic to be followed by general discussion.

The presentation will be graded so it important that all group members talk about 1/3 the time.
