Question

QUESTION 6 1. (10 points) Use least number of 8x2 ROMs only to implement the 3-input, 3-output digital circuit described below. You can only use inverters if needed, but not any other gates. Your solution should use the least number of 8X2 ROMs and least number of inverters, only. Draw a neat, labeled diagram showing interconnections between the ROMs, address and data lines, and the contents of each ROM. Z(a, b, c) = (0,3,5,6) X(a, b, c) = a obec Y(a, b, c) = 2(4,5,6,7) Attach File Browse My Computer Browse Content Collection

Answer 1

x = { (0,3,5,6); 4 = {(1, 5, 6,7). = a b c 3 variable Xor gate a b cx I > x={(1, 2, 4, 7) o I I - If we observe - cccole closely, here cc - – oolo 0-0-0-0 -oo-o- -o toos wr – al z is complement of X. means all min terms which are missing in z are present i in x = x= Inverter is a single and So A A single single 8x2 8x2 enough to Implement Roma Rom all S outh 8 XQ ROM, lo 1ooo lool fwpe – o 882 Inputs a MB IMSB to en CLSB OR zo NOT outputs хо
