Does anyone know what the 64 bit registers are? Aren't then rax,rbx, etc.? Can anyone make a sample working program using 64 bit registers?

mm0,mm1,mm2,mm3,mm4,mm5,mm6,mm7?

Yes but I thought there was also rax,rbx,rcx, etc. too.

Not on x86...

The 64 bit registers you're asking about are those of the all new, all singing, all dancing AMD64 processors (Operon & Athlon64).

They aren't available in just any old common or garden processor, you've got to go for an up market, suave, high brow processor. They type of processor that drinks tea, while sticking its little finger out.

It's not the sort of processor that the proles can afford, only those with their own fifedoms can buy one.

Please enlighten me because i am mostly ignorant on hardware.

I run a athlon xp 1800+

So do i have 64 bit registers?

Only the MMX registers are 64 bit on the Athlon. The FPU registers are 80 bit. XMM registers are 128 bits. You'll have to get a x86-64 processor for access to rAX, rBX, rCX, rDX, rSI, rDI, rBP, rSP.

thanx

No wonder my brother said you will pay a lot more for a pentium.

What about their opcode? A=0 C=1 etc.

Yay! Thanks a bunch. Can anyone make a sample program for me with the mm0,mm1 and all of the other 64 bit registers that can be used on most processors?

take a look at this http://www.xicomputer.com/products/mtowerop.asp
i could not believe the price

pc of my dreams costs $24,869

Talkin about overkill, and the upgrades are pricey too.

Wish they'd atleast have thrown in a 17 inch monitor and more than 32MB video card.
