64-bit
(foldoc) | 64-bit
A term describing a computer architecture with an
ALU,
registers and data bus which handle 64 bits at a time.
64-bit processors were quite common by 1996, e.g. Digital Alpha,
versions of Sun SPARC, MIPS, IBM AS/4000. The PowerPC
and
Intel were expected to move to 64 bits at their next generation -
{PPC
620} and Intel P7.
Being able to deal with 64-bit binary numbers means the
processor can work with signed integers between +-2^32 or
unsigned integers between zero and 2^64-1. A 64-bit {address
bus} allows the processor to address 18 million gigabytes as
opposed to the mere four gigabytes allowed with 32 bits. In
1996 hard disks could already hold over 4 GB. Floating
point calculations can also be more accurate.
A 64-bit OS is needed as well to take advantage of the CPU.
In 1996 there were only a few 64-bit operating systems,
including OS/400, Digital Unix, Solaris (partialy). A
32-bit OS can run on a 64-bit CPU.
