Hello!
I am working on the second phase of the binary bomb/bomblab project, and I am a bit stuck.
Basically, we have to input 6 integers to keep the bomb from exploding - however they must b...
I'm trying to finish a program that prompts the user for an integer and outputs the number in hex format. Yes...this is for an assignment, but I'm looking for some suggestions on which lines ...

Why does memory access take more machine cycles than register access?
Assembly Language for Intel-Based Computers.
I'm trying to get the value of the register of eax at the address 0x8048dc0. The assembler dump is below. Basically it reads 6 numbers and compares them to value of eax and the above memory l...
I'm working on phase three of the bomb and I think I have a general idea on what kind of input I need was wondering if someone could verify.
It looks like I need to pass two inputs and the ...

Is this correct?
Hey,
I need some help with translating C code to mips assembly.
A few things I'm unsure about the mips code I wrote are:
Not exactly sure how to test or use arguments.

Some computers have explicit instructions to extract an arbitrary field from a 32-
bit register and to place it in the least significant bits of a register.
Find the shortest sequence of ...
I tried several times but couldn't get it, perhaps i missed some point in the loop or keeping track of the stack, here is my disassembled code of phase_2. I don't think i understood clearly ho...
write an assembly program to display the machine code that corresponds to a given i86 assembly language instruction.
1. the program should translate i86's AND & ADD assembly language instru...

I have the following scenario: I have an input byte (IN) with the value 0-255 in it and I want to calculate a 2-byte output word (OUT) from it which should grow in an exponential way. So IN=0...
I'm learning some assembly language from a book written for the ol' 16-bit 8086. However, I'm on an AMD64 (Turion X2).
My question is: does this matter? Will this 16-bit code run on my 64-bit...
I read most of the explanation that infinity08 gave to others and it helped me a lot to figure out the previous phases. thanks a lot for your effort and willingness.
Now I'm trying to figur...
