1. How could you use your ALU to compute a bitwise Xor function of two 8-bit numbers? [Hint: you might need to use it multiple times.] 2. Would you expect your ALU to run faster, i.e. take less time for its output to stabilise at a true or false value, when f is zero or when f is one? Briefly explain your choice. 3. What extra input and output would you need to add to your 8-bit ALU to make it useful for adding 16-bit numbers, either in a sequential circuit or in software?

I can’t understand these problems. Could someone explain how this works?

Write the C code that turns off the 3rd bit in the variable x but turns on the 2nd bit.

Write an ASM program that evaluates the following expression, using variables:Z = (A - B) - (C - D)1. Declare and initialize the memory variable A to 32-bit signed integer value -543210and variable B to 16-bit signed integer value -3210.2. Declare the memory variables C and D and read in their values from the keyboardas 32-bit signed integer value -43210 and 8-bit signed integer values -10, respectively.a. You should display a message asking for the value of the variable, for example: “What is the value of C?” then b. Read in the value of C from the keyboard and then c. Display the value you have read beside (ie, to the right of) the message “What is the value of C?”. Then repeat for variable D in the next line.3. Variable Z should be declared as a 32-bit signed integer. 4. Display the string “Z = (A - B) - (C - D)” alone in a single line.5. Display the values of all the variables A, B, C, D together in the next line (in the order in which they appear in the expression); each separated…

Hello, I really need help with this problem. The answer that I got was 1.4 but my professor told me I got the wrong answer so I was wondering if you can help me solve this problem because I really don't understand what I keep doing wrong.
