Where can I get the complete instruction set for a 32 bit microproccer? I plan to do computationally intensive programs, and find 16 bit to be limiting. A simulator would be great. I'm not so interested with 8051 compatiblity since I don't have to much invested in it.

I looked at some pentium data sheets but did not find any instruction sets. The pentiums look pretty complicated. I might have to go to something in between a pentium and a philips XA.

I do realize that even an 8052 can do almost any operation, but the programing has proved to be overwellming. I hope that with a more advanced IC, I will be able to use a more powerfull instruction set. Otherwise I might explore putting a lot 8052's in parellel.
