I am a grad student in Instructional Technology who will graduate in June. I have begun the job hunt already and as I have been reading through qualifications and requirements I am beginning to see a trend of "experience necessary", and usually 5 plus...

I too have no experience but lucky thing I work for the school board and have a little 'toe' in the door .
I can definitely relate, I too will be getting my Masters in Instructional Technology this semester.

Lets say we have an average of one page fault every 20,000,000 instructions, a normal instruction takes 2 nanoseconds, and a page fault causes the instruction to take an additional 10 milliseconds. What is the average instruction time, taking page faults...
Answer Snippets (Read the full thread at stackoverflow):
20,000,000 instructions, one of them will page-fault
Therefore, the 20,000,000 instructions will take
(2 nanoseconds * 20,000,000) + 10 milliseconds
get the result (which is the total ....
2.5 nanoseconds? Pretty simple arithmetic, I guess.

Do graphic cards have instruction sets of their own? I assume they do, but I have been wondering if it is proprietary or if there is some sort of open standard.
Is every GPU instruction preceded by a CPU instruction or is it seamless? That is does OpenGL...

AMD does even provide the specification up to the HD4000 series at the moment .
Yes they do.
The GPU instructions are executed independent from the CPU instructions.
Yes, the GPU have their own proprietrary instruction sets.

Is there CIL instruction to exchange the first two elements in the stack?

Answer Snippets (Read the full thread at stackoverflow):
Looking at a list of CIL instructions there doesn't appear to be a single instruction that exchanges....
However, using stloc , pop , and ldloc , you should be able to accomplish your exchange .
There is no single instruction exchange.

Hi Does iphone processor ARMV6 supports MMX instructions?

Answer Snippets (Read the full thread at stackoverflow):
ARMs are a bit configurable....
The iPhone uses an ARM processor so you can't use MMX .
MMX is a SIMD instruction set for x86.
Looks like ARMV6 has a SIMD unit of some kind.. .

If the program counter points to the address of the next instruction to be executed, what do frame pointers do?
Answer Snippets (Read the full thread at stackoverflow):
This is very implementation dependent (and more....
The point is that the frame pointer is fixed during the life of a method while the stack pointer could move during execution .
Usually the return address (but sometimes just past last argument, for example) .

This is definitely obsessive, but I am fascinated by how cleverly the compiler translates C code into machine instructions. Since I am a little fuzzy on some instructions, it would be helpful if I could watch the operation of a compiled program at the...

Then use Run/Step into(over) instruction to step in assembly.
Wait till you hit a breakpoint.
In the Debugger window, enable assembly: Run/Debugger display/Source and disassembly .

Some old x86 instructions are undefined in 64-bit mode. For instance LDS , LES and LSS , or short opcodes of the INC r16 ( 40 + rw ) and INC r32 ( 40 + rd ) instructions.
Are there any instructions that are defined only in 64-bit mode, and not in 32-bit...

Answer Snippets (Read the full thread at stackoverflow):
In 32 bit mode, this is only available with branches (aka branch offset), in 64 bit mode you can form effective adresses for any memory operand... .
There is an adressing mode, which has no counterpart in 32 bit: Instruction pointer relative adressing.

No, it's a transaction control (TCL) statement, not a data manipulation (DML) statement .

I need to use the popcnt instruction in a project that is compiled using Visual Stdio 2005
The intrinsic __popcnt() only works with VS2008 and the compiler doesn't seem to recognize the instruction even when I write in a __asm {} block.
Is there any way...

Answer Snippets (Read the full thread at stackoverflow):
Assuming you've set up VS2005 like this to do assembly language, then you could get a hold of the SSE4.1 manual from Intel and code a macro for each SSE4.1 opcode that you needed as per this thread at masm32.com... .
Okay, this is a wild guess thing but ...
