Now that I am faced with the scenerios were 32 bits is not enough anymore,
the transition to 64 bit feels too expensive.
I worry/fear that most of the upper 32 bits of the 64 bit integers for
example will not be used and thus are populating the data caches and also
instruction caches.
Those caches are very important.
I think 48-bit computers might give 25% more performance than the same
64-bit computer.
Thus my questions are:
Did you guys consider creating 48-bit computers ?
Ofcourse the memory system would have to be 48-bit as well.. so that 48 bits
can be retrieved all at once for maximum efficiency.
And a 48-bit processor with 48-bit registers.
And finally 48-bit compilers.
I think eventually most programmers would probably be a little bit more
happy with that because it will make their software run faster.
For now die-shrinks and transitions to lower nanometers might be possible,
but perhaps in a few years that might seize to exist.
Thus perhaps a transition to 48-bit might have made more sense, and might
still make some sense.
Commercially it be more interesting for chip manufacturers...
48-bit computer will last about 20 years. While 64 bit computers will last
abour 35 to 40 years.
Selling 48 bit computers now would have allowed you to sell 64 bit computers
in the future.
