Reading Quiz 9

Credit:

5 points.

Reading

Be sure you have read, or at least skimmed, Chapter 3 of the textbook.

Instructions

Answer the questions below using only the course textbook (i.e., no Web searches). Please work independently rather than in groups, and include the Honor Code pledge in what you turn in, either the full pledge or just the word “pledged”. (Please put this in the same document as your answers, so I don't overlook it.)

You may write out your answers by hand and scan them, or you may use a word processor or other program, but please submit a PDF or plain text via e-mail to my TMail address. (No links to shared files on Google Drive please.) Please use a subject line that mentions the course and the assignment (e.g., “csci 2321 quiz 9” or “computer design quiz 9”).

Questions

1. (2.5 points) The tables in Figures 4.12 and 4.13 include some values of “X”. What do those mean?

2. (2.5 points) The textbook says all but one of the control signals shown in Figure 4.15 can be determined from the instruction. What's the exception and what else do we need to generate it?
