Complexity Growth Source (Copp, Int. AOC EW Conf., 2002)

Reliability and Cost Reliability VLSI circuits are more reliable than ever—How do we continue on this path? Cost Products are more affordable as cost of digital components is dropping  2 MB flash memory ($ , 1988)  256 MB flash memory ( $55.00, 2003) Must continue to contain the cost

Course Boot-Up Discussion Section: Originally on R from 5:00 to 6:00pm How about on W from 5:00 to 6:00pm? Midterm exams also on W from 5:00 to 6:30pm? Tentative Tutorial Schedule Assignments Read Chapters 1, Homework #1 will be due Wednesday, February 2 nd (assigned early next week)

 P Systems Overview

Embedded Systems and Applications Embedded microprocessors account for about 94% of all microprocessor sales. Embedded microprocessors extend over a much larger performance range than PC’s. Terminology GP Systems vs. Embedded Systems What are the key design parameters?  P System Structure Embedded System Design Flow Why have a structured design flow?

 P Systems Overview
