Mallard ECE 290: Computer Engineering I - Spring 2007 - Graded Web. .. https://mallard.cites.uiuc.edu/ECE290/webgrade.cgi?SessionID=mding3. .. 1 of 2 2/23/2007 3:18 PM Graded WebQuiz: ROMs You have submitted this WebQuiz 2 times (including this time). You may submit this WebQuiz a total of 10 times and receive full credit. Question #1 Fill in the ROM truth table for an 8 x 3 ROM that implements the following three Boolean functions: A(x,y,z) = OR(m1, m2, m4, m6) B(x,y,z) = x XOR y XOR z C(x,y,z) = (x XOR y XOR z)' For each address xyz, specify the 3-bit word stored at that address. x y z A B C 0 0 0 0 0 1 0 0 1 1 1 0 0 1 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 1 0 1 0 0 1 1 1 0 1 0 1 1 1 1 0 1 0 You have filled in all 24 entries in the table correctly. You received a raw score of 100% on this question. Question #2 Suppose you are asked to design an integrated circuit chip for a ROM of size 512x12 bits. The chip must have two chip select inputs and operate from a 5-volt power supply. How many pins are needed for the IC package? 25
