the 64 bits of physical memory was given by my professor. He knows that it is not realistic.

An other, question how do I figure how many bits are needed for an offset, how many physical page and how many virtual pages. again using 8 bit addressing. 64 bits phyical memory and a page...

This is part of a a homework assignment, I want to make sure that I am understanding correctly. In class, my professor said that in direct mapping using 16 bit addresses, we have 4 tag bits,...

what mean? I know that they are hex values but why are these four important?

correct, it the At&T style. It is was unfamilar to me (like most assembly is, since this project is the first exposure I have to assembly.

I know am I looking for a int and har and a int again. I am not sure break I need to to break or what mozbl or movb is?

First, yes, this bomb is a common assignment (yale to communty college)Therefore, I am in the usa. A google search will confirm this. To catus, ours does not report back (that code was ...

I am using emacs. I am in the shell, using gdb, and when I do disas what ever, it does off the screen what to I do so I can view the whole thing?

I get that is where the compare is. Because if I entered 1 2 3 4 5 6 as the input and do a break at
0x080488df <phase_3+57>: cmp %eax,%edx then print $eax I get 4 for eax and 1...

I am really stuck on phase 3. Since the 1st and fourth numbers (same for the 2nd & 5th and 3rd and 6th) should be the same numbers to
defuse the 1st bomb,
I confused as to where to begin looking to...

I would but do not know what to use/how to do so.

I need to convert decimal to IEEE 32- floating point for a couple homework problems by hand. I was wondering if my answers were correct.

My exposure to arrays and pointers are bit limited. And concatened strings even less ( it was not covered in my class so I had to use my book. ) So I know there are errors. I can not use...

Function Operator that this function emulates Operators you may use

This is what I need to to do:

Write 4 C functions, as specified in the table below, which emulate the C operators |, ^, ~, and !=. You may use only straightline code (i.e., no loops or...

I can not figure out why I am getting compling errors . can someone help? And it there another number to use for bitnot besides -1?
