We have been given the assembly code:
add $0x2e,%rcx
If the value of %rcx before this line of code is executed is 6, what is it afterwards? Briefly explain why.

Write a simple code(AVR assembly code) to load the value 0x15 into location 0x67 and add it to R20 five times and place the result in R20 as the values are added. R20 should be zero before the addition starts.
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...
