Complexity Growth Source (Copp, Int. AOC EW Conf., 2002)
Reliability and CostReliability 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 ($2800.00, 1988) 256 MB flash memory ( $55.00, 2003)
Must continue to contain the cost

Course Boot-UpDiscussion 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 ScheduleAssignments Read Chapters 1, 2.1-2.6 Homework #1 will be due Wednesday,
February 2nd (assigned early next week)
P Systems Overview
P Systems OverviewEmbedded 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 StructureEmbedded System Design Flow Why have a structured design flow?
