1. What is wrong with the command
movb $0x3A2C, %bx
a) Neither 3A2C nor bx should be used with byte instructions.
b) The dollar sign can't be used with a hex constant.
c) bx is too small to hold 3A2C and should be changed to ebx.
Q1. What is wrong with the command

What is wrong with the command movw $0x43FF, %al The command should be movb because the al register holds a byte. Hex constants can't be used with dollar signs. al is not big enough to hold 43FF.
1. Assume that you are given values in eax, ebx, ecx. Write an assembly code that does the following: eax = (ecx + edx ) - (eax + ebx) 2. Write a piece of code that copies the number inside al to ch. Example: Assume that Initially eax = 0x15DBCB19. At the end of your code ecx = 0x00001900. Your code must be as efficient as possible. 3. You are given eax = 0x5. Write one line of code in...
Consider the language ins, for example, the words 1, 11 and 11111111, but neither 111 nor 1111111111 1. Prove that L is not context-free. 2. Draw a standard Turing machine with a two-way tape that decides L, using only ?-(L B} as tape alphabet. Very briefly explain how your machine works For every state or group of related states, your explanation should say in a few words (e.g. move back to start of tape" or "replace every blank by 1")...
Assume an integer is represented on 1 byte. What is the problem with adding the following two binary numbers? 0111 1111+ 0100 0001 -------------- 1100 0000 A. There is nothing wrong B. The answer is correct; it should be 0100 00100 C. The answer is incorrect; it should be 0110 0000 D. The sum of the two numbers is to big to be represented only one byte.
Please make sure your answer is correct. I have gotten numerous
wrong answers. Thanks.
This one too:
And this one:
Again please make sure you are correct.
If you have time: This one was marked wrong too, so if you can
solve I give thumbs up thanks.
