A 4-bit carry-look ahead adder (CLA) is used to add the two numbers: A(A3A2A1A0) = 0110 and B (B3B2B1B0) = 1001 with an external carry-in C0=1. Use the CLA carry-out equation ( Si = Pi Ci , Ci + 1 = Gi + Pi Ci Where Pi = Ai Bi and Gi = AiBi) to compute the values of following outputs?I. Carry-Out = C3II. Sum = S3
Design a BCD to Excess-3 code converter. Transforms BCD code for the decimal digits to Excess-3 code for the decimal digits. BCD code words for digits 0 through 9: 4-bit patterns 0000 to 1001, respectively. Excess-3 code words for digits 0 through 9: 4-bit patterns consisting of 3 (binary 0011) added to each BCD code word. In other words, Excess-3 code is a decimal digit plus three converted into binary, i.e., 0 is 0011, 1 is 0100, etc. A) Draw the truth table for this circuit. Hint: do not forget Don't Cares. Input BCD Output Excess-3 АВСD WXYZ 4.
Q1.Write a Verilog code for the 16 bit ripple carry adder. The hierarchy of 16 bit ripple carry adder is shown in figure below. The ripple carry adder is made up of four 4 bit full adder, each 4-bit full adder is made up of four full adders which in turn made up of two half adders and OR gate. Finally each half adder is made of xor, nand and nor gate.
computer engineering: PLEASE HELP Design a 4-bit 2’s complement format adder/subtractor circuit that is also capable of indicating the occurrence of an overflow condition. The circuit has two 4-bit inputs, P and S, and a 1-bit input Op. The value of Op specifies whether the operation to be carried out is addition or subtraction. The outputs for the circuit are R (4-bit wide) and Ov (1-bit wide; Ov =1 indicates the occurrence of an overflow during the addition/subtraction process and Ov = 0 indicates that there is no overflow). Verify your design’s functionality with Multisim by performing both P + S operation as well as the P − S operation for each of the following pairs of P and S values: P = 0000 and S=0000 (i.e. P = 010 and S = 010) P = 0110 and S=0100 (i.e. P = 610 and S = 410) P = 1110 and S=1000 (i.e. P = −210 and S = −810) P = 1000 and S=0100 (i.e. P = −810 and S = 410) (Eight cases in total: Four P+S cases and four P-S cases). As an example, when P = −2 and S= −8 as in the…

Arithmetic using Verilog Create Verilog modules for a half-adder and a full-adder. Using these half-adder and a full-adder modules, create a Verilog module for a 4-bit multiplier. Then create a test fixture for the 4-bit multiplier and produce its simulation result. The stimulus for the test fixture of the 4-bit multiplier must be generated for all combinations of a[3:0] and b[3:0]. Assume that all inputs and output are unsigned numbers. You are NOT allowed to use the arithmetic operators (+, - , *) in your Verilog codes. Provide all the following in pdf format. • half-adder module • full-adder module • 4-bit multiplier module • 4-bit multiplier test fixture • 4-bit multiplier simulation results They must be generated as pdf documents directly from Xilinx. Copying and pasting to other software, screenshot, saving as image, or any editing method is not acceptable.

One way to calculate the parity of a 32-bit number in EAX is to use a loop thatshifts each bit into the Carry flag and accumulates a count of the number of times the Carryflag was set. Write a code that does this, and set the Parity flag accordingly
In this problem, we will design a parallel adder for adding three positive binary numbers. These numbers are designated Xp,.X3,X2X1, Yn...Y3,Y2,Y, and Zn,.Z3,Z2,Z1. The following one-bit adder cell is used in this n-bit parallel adder. In this case, there would be two carry out signals, D1 and Do, and two carry in signals, C1 and Co. Two carry signals are required because three binary digits are added with the two carry bits coming into the cell. a) Derive a truth table which specifies the complete operation of this one-bit adder cell b) Derive a Boolean equation for Si in minimum form (Equations for D1 and Do are not required.). c) Draw the adder diagram for adding three positive binary numbers considering each binary number is n-bits.

In this exercise you are to construct an ALU with the following specification: • The ALU takes 3 different 32-bit inputs: A, B, C; and has one 32-bit output: D. • The ALU supports 7 different operations: – A + B (addition) – A - B (subtraction) – MAX(A,B,C) – MIN(A,B,C) – A & B (bitwise AND) – B & C (bitwise AND) – (A + B) & C (addition followed by bitwise AND) To construct this ALU you will follow a modular design. Assume you have an unlimited number of the following gates and combinational circuits at your disposal, but no others: • 2-arity AND gate, • 2-arity OR gate, • NOT gate, • 2-way MUX, • bit-wise AND circuit: it takes two 32-bit inputs and has a 32-bit output which is the bit-wise AND of its inputs. • 32-bit ADDER: it takes two 32-bit inputs, a 1-bit control signal, and has a 32-bit output. If the control signal is 0, the circuit outs the sum of its inputs. If the control signal is 1, the circuit outputs the difference of its inputs. The inputs and outputs are…
b- Design a sequence detector of the pattern 0100 where the circuit accepts a serial bit stream "X" as input and produces a serial bit stream "z" as output. Whenever the bit pattern "0100" appears in the input stream, it outputs z = 1; at all other times, z = 0. Overlapping occurrences of the pattern are also detected.
