Kat, I would recommend TSMC for the CPU.  You will need their 0.13 
micron process with copper interconnect. Even then, you'll need a 
highly parallel design. Once you have the design complete, make sure 
you have a million dollars left for masks and the first fab run.

For the DDR, I think you should save your second million bucks and 
use existing devices. Why do you need an 8-bit device? To get 10 TB 
you will have to stack up an awful lot of chips, so the width of each 
chip shouldn't be a major consideration. I trust you're not thinking 
you can get 10 TB on a single chip.

This is not the sort of post I expected on this group, though I 
recognize you as a regular. Is there any chance you could divulge the 
application? In particular, if you need Gflops why are you 
constrained to an 8-bit CPU? I think you should be looking at 32-bit 
IP cores such as ARM, ARC, MIPS, TenSilica, etc. if not 64-bit.
