CSCI 150 3. (5pt) Combinational Circuit designs A. A comparator is a component that compares the value of two numbers, and determine whether one is greater than the other, or equal to one another. You need to design a 1bit comparator, with X, Y as 1bit inputs, G, E as 1 bit outputs, where G = 1 if X > Y, E = 1 if X Y. Draw the truth table, then write down the boolean expressions after optimisation. (2.5pt) B. Design a 2bit comparator using two 1 bit comparators, where X and Y are 2bit inputs. (2.5pt)

Q3) The value of the DS register is 3032H. And the BX register contains a 16 bit value which is equal to 3032H. 0008H is added to BX. ADD BX, 0008H The register AX contains some value which needs to be stored at a location as follows: MOV [BX], AX Calculate the address at which the value of the AX will be stored.

A digital circuit for adding two binary digits has two inputs: the two digits to be added; and two outputs: the units bit and the twos bit of the answer. (a circuit of this kind is called half adder.) By treating this as two circuits, each with a single output, use Karnaugh maps to obtain a Boolean expression for each circuit, and draw the corresponding circuit diagrams.

I got 32,000 and that wasn't correct. Not sure how to do this thanks

Write a VHDL program to implement a 2-bit adder. The Boolean functions for the 1-bit full adder are given in the diagram:

1. Gray code to Binary converter: Gray code is one of the codes used in digital systems. It has the advantage over binary numbers that only one bit in the code word changes when going from one number to the next. (See Table 1). Design a combinational circuit with 4 inputs and 4 outputs that converts a four- bit gray code number into an equivalent four-bit Binary number. Use Karnaugh map technique for simplification. Use LogicWorks for pre-lab demonstrations. Select the library "7400dev.clf* in the Parts Palette and then select the XOR chip 74-86. This would give you a set of 4 XOR's as shown in Fig. 1, just like the hardware chip 74-86. You could use as many as needed from these XOR gates in your design. Get back to ALL LIBRARIES and select switches for the inputs and Binary Probes as indicators of the outputs. Verify your design in the pre-Lab. During the Lab construct the circuit and verify its operations.
