1. Complete the TABLE 1 truth tables on the answer sheet for a one-bit ALU that has 6 inputs: Two operands A0 and BO, Cln0 (the carry-in), control bits F2 FI FO (so, 011 is ADD which means F2 = 0, F1 = 1 FO = 1). The two outputs are: CO (the results of adding/anding/oring two binary digits) and COut0 (the carry out from adding the two binary digits)

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...
Given the Function F1(w, x, y, z) and F2(x0, x1, y0, y1), write the truth table for each function. F1(w, x, y, z) - Specified by the lab instructor F2(x0, x1, y0, y1) is a two bit adder. The function F2(x0, x1, y0, y1) has 3 outputs - 2 bits for the sum and 1 bit for the carry out Cout 3. Given the Function F1(w, x, y, z) and F2(x0, X1, yo, yı), write the truth table for each...

Design a circuit with three inputs (A, B, C) and two outputs (F1, F2). The first output F1 is logic 1 if the number of l’s in the binary number is less than the number of O's, otherwise F1 is logic 0. The second output F2 is 1 if the binary input is 2, 4, 5, 6,7 otherwise the second output F2 is logic 0. a. Derive the truth-table for F1 and F2 as a function of the 3 inputs....
Finite state machine (FSM) counter design: Gray codes have a useful property in that consecutive numbers differ in only a single bit position. Table 1 lists a 3-bit modulo 8 Gray code representing the numbers 0 to 7. Design a 3-bit modulo 8 Gray code counter FSM. a) First design and sketch a 3-bit modulo 8 Gray code counter FSM with no inputs and three outputs, the 3-bit signal Q2:0. (A modulo N counter counts from 0 to N −...
PROBLEM STATEMENT The mini-calculator will use a small ALU to perform arithmetic operations on two 4-bit values which are set using switches. The ALU operations described below are implemented with an Adder/Subtractor component. A pushbutton input allows the current arithmetic result to be saved. An upgraded mini-calculator allows the saved value to be used in place of B as one of the operands. The small ALU that you will design will use the 4-bit adder myadder4 to do several possible...
