Unformatted text preview: CPSC 121 Lecture 14 February 6, 2009 Menu February 6, 2009 Topics: Overflow in n-Bit Binary Addition/Subtraction (revisited) (More) Examples (contd) Reading: Next: Epp 3.1, Theorem 3.4.1 (page 157), Representation of Integers (pages 159163), Epp 3.6, and 3.7 Reminders: On-line Quiz 7 deadline 9:00pm February 8 Assignment 2 due Friday, February 13 (by 17:00) Marked Assignment 1 available in tutorials Midterm exam Tuesday, February 24 (evening) READ the WebCT Vista course announcements board Coming soon: After covering the cited material in Epp chapter 3 we will go beyond Epp to talk about a new category of circuit, called a sequential circuit. This, in turn, will allow us to explore, at the circuit level, a full (albeit simple) computer. Associated readings from Epp are Epp 12.2 (pages 745747) and Designing a Finite Automaton (pages 752754, skipping part b of the examples). Well reread and revisit this material later. The objective for now is to build intuition for how a finite-state automaton works. Today, we return to the combinational circuits described in Lecture 10 to revisit the issue of detecting overflow in n-bit binary addition/subtraction and, time permitting, continue with the examples introduced at the end of Lecture 13....
