adv. CPU questions.

[Bmxpunk86pl]

the registers are places to hold data while the cpu is working on them right? Are the registers the cache? if i have more cache on my cpu does the amount of registers increase?

Will x86 Assembly work on a AMD cpu, or on a 64-bit cpu?

Assembly is very CPU specific I think. Registers are not cache, a Duron with little cache will likely have the same registers as a Athlon with lots more cache.

Registers are used when doing calculations - the data is stored temporarily in these registers.

It has been a while, but I think I remember. Penguin(David) is correct. Registers are not cache.

I think that x86 assembly will work on AMD chips, but will NOT work on 64bit.

Ridenow...

First thing is that when ever I'm in doubt about a tech issue I try www.webopedia.com first, second it of course google....

As to your question. The registry is not the same as the cache, you can think of the registry as residing much closer to the CPU. The registry feeds the CPU it's next calculation and the pieces of the calculation, which it gets from memory, the cache (level 1 or 2), or a cache on another component.

Is it not www.pcwebopaedia.com ?
Its very useful - we use it at school for research into computing things.

Hey David,

I just use the straight www.webopedia.com, seems to resolve to the same IP as www.pcwebopedia.com.....
