Question

BIT MAXIMUM VALUE SELECTOR Consider a simple device that takes two 2-bit binary inputs representing two values ranging from zero to three. The 2-bit value A is represented by two input variables Al and A0. Values of Al and A0 will be used to encode numeric values (in binary) as described below. 2-bit values for the second 2-bit input B and the 2-bit output C are encoded similarly. The 2-bit output C of the de- vice will be the greater of the two values presented on the 2-bit inputs A and EB. A1 A0 A1A0 B1B0 CIC0 Value C1 CO 00 Zero 01 10 Two 11Three One B1 B0 Figure 1: The 2-bit priority selector and value encoding table Consider a case in which the 2-bit value A encoded the value "One and the 2-bit value B encod- ed the value "Two". In this case, the 2-bit value C should encode the greater of these two values ("Two"). At the digital level, the value A would be represented by two input variables Al and A0 which would have the values 0 and 1, respectively. The value B would be represented by two input variables B1 and B0 which would have the values 1 and 0 respectively. The output value C would be represented by two output variables Cl and C0 which should have the values 1 and 0 respectively LAB 3-TWO-LEVEL IMPLEMENTATION The goal of this lab is to design a two-level solution for this device, simulate the device (and test your design), then to physically realize the device using AND, OR, and NOT components. Please document all of vour work in your lab notebook. Design (2 points) . Construct a truth table that demonstrates completely functionality of this device. . Construct a set of Boolean equations in SOP form that describe the required behavior of the output variables C1 and C0 in terms of the inputs variables A1, A0, B, and B0 Minimize your equations using Boolean Algebra. Clearly state each step in your minimization. Draw a logic diagram for two-level implementation of your SOP equations. .
