Considering "x86" ranging from 8086 up to 80486 (ok, Pentium too) 32-bit CPUs ,

there are 29 registers , as follows :

EAX, EBX, ECX, EDX, ESI, EDI, ESP, EBP, EIP, CS, DS, SS, ES, FS, GS, "Status(Flags)-Register" CR0, CR2, CR3, TR4, TR5, TR6, TR7 DR0, DR1, DR2, DR3, DR6, DR7

How do you find out how many bits your processor has and how many bits your Opertaing System runs on?

Goto start -> Run and type winmsd.exe. This will bring up system info page. If the string next to Processor is x86, its a 32 bit machine . If the string next to processor is ia64 or AMD64 then its a 64 bit machine. Source: http://support.microsoft.com/kb/827218 cheers, Esha


How can you run a Super Nintendo emulator on a PlayStation 3 without Linux?

You cannot that I know of. For one thing, the ps3 operating system is not an open operating system that allows its user to install random software like windows or linux does. For another thing, running software made for windows (or any x86 system, which is what most game emulators are programmed for) requires an x86 emulator to run on the cell processor of the PS3. So you would need to use an x86 emulator (like qemu) on linux and from there run the gaming emulator. I believe there are some super nintendo emulators that will run on linux on the PS3 without qemu, for example, snes9x. But no, you cannot simply run an emulator from the ps3 without linux. The Ps3 operating system will not run executable files like windows does.

Will x64 operating systems work on a computer running x86?

x86 and x86-64 (x64) are not mutually exclusive. x86-64 is a superset of x86, with 64-bit instructions. Many people still run 32-bit (x86) applications and operating systems on 64-bit processors. The reverse is not possible, though; you can't run a 64-bit system on a processor that only supports 32-bit.

What is the function of Accumulator register?

AX is one of four general purpose registers in Intel's x86 architecture. It's primary function is to store result of some mathematic operations (or in other words accumulate their results). In the later generation of processors it become parto of EAX register. It is probably still present in your CPU, if you have x86 compatible processor.
