Win, Re: <Big numbers can be handled by other means than increasing the basic machine word.>

Yes, you're most likely right.

But my take on the subject is that increasing the machine word size is the easiest way to get the instructions and data through the CPU quickly.

But I'm a software guy. My function is to make the instructions and data as small as I can.

I would assume the hardware guy's job is, in part, to make the hardware eat data and instructions as fast as possible.

Increase rate and increase size.

In any case, when did 4 bit computing to to 8, 8 to 16, 16 to 32, and 32 to 64?

What's the trend?

<128 bits can address, um, 10**38 bytes, which might conceivably be useful for a shared universal address space or capability based machines or something.>

The idea that we will ever need 128-bit byte addressing is preposterous. There are only about 10**42 atoms in the universe. Such computer can't be constructed.

128-bit IP addressing is a different story. The spammers would love to send junk e-mail to every single atom in the universe.
