Use byte addressableinstruction.c) Make RE0, RA1, RB2, RC3 and RD4 HIGH.result discussion conclusionDraw the control unit and datapath for the following algorithm that returns an integer value. The function takes two points (x1, y1) and (x2, y2) and computes the equation for a line. It then evaluates and returns ynew for the parameter xp using that line. Use a 16-bit data bus. Show your work; label and clearly mark your diagram. Do not implement this in VHDL. int PredY(int x1, int y1, int x2, int y2, int xp) { int m, b, ynew; if (x1 – x2) <> 0 { m = (y1 - y2) / (x1 - x2); b = y1 - m * x1; ynew = m * xp + b; return(ynew); } else { return(65535); // that's a 16-bit FFFF } }Assume we have a 16-bit Arithmetic Logic Unit (ALU) that has three inputs and three outputs. List the inputs and outputs in binary for the ALU if we are using it to determine if X = 2510 < Y = 3210. The ALU. Use 16 bits or 1 bit to represent the inputs and outputs as appropriate. The value for ALU operation will be (11)2 for Set on Less Than.
- Show an image of the completed 8 BIT ALU The most important and possible most difficult component to implement is the arithmetic logic unit. Thefunctions of the ALU are shown in Table 1. The ALU should have 5 inputs (A-input, B-input, F0-input, F1-input, Finput) and 1 output (C-output). You will need to determine how many bits each input and output should have.Remember, you are designing an 8-bit microprocessor! To achieve the specified ALU functions, think aboutwhich digital logic component(s) you can use to accomplish the task. For example, to add the value on the A-bus8-bit ALUto the value on the B-bus, you can simply use an 8-bit adder. Explore the components in Logisim! Additionally,you can think about using a multiplexer to determine which ALU function will be performedDesign a circuit that takes three bits, X2, X1, X0 as input and produces one output, F. F is 1 if and only if 2<=X<=5 when X = (X2, X1, X0) is read as an unsigned integer. For example, if X2=1, X1=0, and X0=0, then the unsigned binary value is 100, which is 4, so the output would be 1. Your Assignment For This Problem Includes the Following Design the necessary circuit using Logisim to implement the situation described above. Use Kmaps for simplification. Be VERY careful to get the correct functions for your output before simplifying and designing the circuit with Logisim. You should minimize the circuit. Your circuit should have three inputs and one LED output. All inputs (X2, X1, X0) and output (F) should be labeled (in Logisim, not by hand). Please use these names to indicate the inputs and output so all projects are consistent. You should also include your name as a label on the circuit. Test your circuit to be sure it is working correctly.Evaluate the following expression using three, two and one address machine format.X= (A-BX C)/(D+EXF)

Additionally,you can think about using a multiplexer to determine which ALU function will be performedBelow is a diagram of a priority encoder chip. In order for the chip to be active the enable, EI, must be ["LOW", "HIGH", "Either LOW or HIGH will work"] For an input pin to be active it must be ["LOW", "HIGH", "Either LOW or HIGH will work"] If the input pin I4 is LOW and all the other input pins are HIGH, the outputs will be A0 = ["0", "1", "Cannot be determined"] A1 = ["0", "1", "Cannot be determined"] A2 = ["0", "1", "Cannot be determined"]1. Design a 4-bit ALU that performs Arithmetic (add, subtraction), and Logicoperations (AND, OR). The following control signals are to be considered:• A/S: add/subtract (0:add, 1:subtract)• A/O: and/or (0:and, 1:or)• A/L: arithmetic/Logic (0:arithmetic, 1:logic)• R/W: read/write signal (0:read, 1:write) Unit 3 (A/L) - Design a 4-bit ALU using Unit 1 and Unit 2. The control signal A/L willindicate which operation the ALU will perform (when the control signal is 0 performArithmetic, otherwise if the signal is 1 then perform Logic).Unit 4 (R/W)- Design three 4-bit parallel registers to hold A, B, and C where C keepsthe output of the ALU. The registers have a R/W control signal that indicates that theyare being written to or read from.
