ECE 2030 Computer Engineering Spring 1999 5 problems, 7 pages Final Exam 10 June 1999 2 Problem 1 (2 parts, 20 points) Two by Two Part A (10 points) Design a toggle cell using only two transparent latches, two 2-to-1 muxes, and an inverter. Use icons for the latch and mux. Your toggle cell should have an active high toggle enable input TE , and an active low clear input -Clear , clock inputs Φ 1 and Φ 2 , and an output Out . The - Clear signal has precedence over TE . Label all signals. Part B (10 points) Now combine three of these toggle cells to build a divide by seven counter. Your counter should have an external clear, external count enable, and three count outputs O 2 , O 1 , O 0 . Use any basic gates (AND, OR, NAND, NOR, & NOT) you require. Assume clock inputs to the toggle cells are already connected. Problem 2 (3 parts, 28 points) Switch Design
ECE 2030 Computer Engineering Spring 1999 5 problems, 7 pages Final Exam 10 June 1999 3 Part A (10 points) For each expression below, create a switch level implementation using NFETs and PFETs. Assume you have the complements of each input. ) ( D C B A Out + = ) ( D C B A Out + = Part B (10 points) For the following behavior (in map format), derive a simplified product of sums expression using a Karnaugh Map. Circle and list the prime implicants, indicating which are essential. Then write the simplified POS expression.
