Using Structural Modeling in VHDL write the code for: An Arithmetic Logic Unit (ALU) shown in the figure below. A (16-bit), B (16-bit), Opcode (3-bit), and Mode (1-bit) are the inputs; and ALUOut (16-bit) and Cout (1-bit) are the outputs of the design. A and B hold the values of the operands. Mode and Opcode together indicate the type of the operation performed by ALU. The ALU components ARE: -Arithmetic Unit that consists of one 16-bit adder, 16-bit subtractor, 16-bit...

6. In this problem, you are to implement a 3-bit ALU which performs the following 4 operations on 3-bit operands A and B and generates the result F and the overflow status OV: (a) op(1:0) 00: A AND B (b) op(1:0)#: 01 : A OR B. (c)op(1:0),# 10: A +13. (d) 01, (1 : 0) t# 11 : A B, For arithmetic operations, assume that A and B are two's complement integers, e.g.. 0112 3, n and 1002 ten The...
For number 2 you can use exclusive-OR gates, but do not use multiplexers. 1. Design a 4-bit adder/subtractor using only full adders and EXCLUSIVE- OR gates. Do not use any multiplexers. 2. Design a combinational circuit using a minimum number of Full adders, and logic gates which will perform A plus B or minus B (A and B are signed numbers), depending on a mode select input, M. If M=0, addition is carried out; if M1, subtraction is carried out....
FIRST ACTIVITY: (100/100) . SIMPLE 4-BIT ARITHMETIC LOGIC UNIT (ALU): This circuit selects between arithmetic (absolute value, addition) and logical (XOR, AND) operations. Only one result (hexadecimal value) can be shown on the 7-segment display This is selected by the input sel (1..0) B A-BI A+B A xnor B A nand B Input EN: If EN-1result appears on the 7 segment display. If EN=0 → all LEDs in the 7 segment display are off Arithmetic operations: The 4-bit inputs A...
