Could you point me to the datasheet for this CPU? I know of a few high end
CPUs which use a 128 bit wide bus to connect to external cache, but
nothing which even comes close to having 1024 bit registers. I just don't
think that's a desirable way to do 1024-bit wide arithmetic on a general
purpose CPU for the next 5-10 years at least. I think 64-bit registers
will be the norm for high end desktop machines and other non-embedded
CPUs in the first decade of the 21st century. Do you have some inside info
on quantum dot devices you want to share :-)
