Reliability and Cost Reliability n VLSI circuits are more reliable than ever—How do we continue on this path? Cost n Products are more affordable as cost of digital components is dropping w 2 MB flash memory ($2800. 00, 1988) w 256 MB flash memory ( $55. 00, 2003) n Must continue to contain the cost

Course Administration Text / Class Notes / Web Resources Course Supplement Course Objectives n Bloom’s Taxonomy Examinations and Grading (Q&A) Documentation Standards Reference Information n Available on course homepage and at Bob’s copy shop

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

P Systems Overview

P Systems Overview Embedded Systems and Applications n n n 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 n What are the key design parameters? P System Structure Embedded System Design Flow n Why have a structured design flow?
