I get that you\'d want to do something like take the first four bits put them on a stack (reading from left to right) then do you just put them in a register and shift them x times to put them at the
My question is specific to iPhone, iPod, and iPad, since I am assuming that the architecture makes a big difference. I\'m hoping there is either a specification somewhere (for the various chips perhap
I am new to Computer Architecture and Design. My question was a high level program Instruction set are executed in CPU one after another. Does it even involve Operating System instructions as overhead
I remember having read a开发者_StackOverflow中文版bout it somewhere… Could anyone shed some light on this?According to Wiki, Pentium Pro. They are suprizingly old, and I wonder why do you still need
I have the next code: movax,@data movds,ax Why I can not write just like this? mov ds,@data All source: .MODEL small
I know about Intel 64 and IA-32 Architectures Software Developer\'s Manuals. I also know that these cover all the legacy & old processor ISAs.
While building my assembler for the x86 platform I encountered some problems with encoding the JMP instruction:
Question What is the (non-trivial) difference between the following two x86 instructions? 39 /rCMP r/m32,r32Compare r32 with r/m32
0x004012d0 <main+0>:push%ebp 0x004012d1 <main+1>:mov%esp,%ebp 0x004012d3 <main+3>:sub$0x28,%esp
Every new generation of CPU introduces some sets of new instructions, i.e. MMX, 3DNOW, SSE and so on.
