MIPS. By contrast, some current supercomputers are rated at in
excess of 1000 MIPS. And yet, these computers, such as the Cray
systems and the Control Data Cyber 200 models, are still tied to the
von Neumann architecture to a large extent.
Over the years, a number of computers have been claimed to be
"non-von Neumann," and many have been at least partially so. More
and more emphasis is being put on the necessity for breaking away
from this traditional architecture in order to achieve more usable and
more productive systems. Obviously, the computers we use today are
not simply larger, faster EDVACs. Numerous improvements have
been made through the introduction of, for example: index registers
and general purpose registers; floating point data representation;
indirect addressing; hardware interrupts to redirect program
execution upon detection of certain events; input and output in
parallel with CPU execution; virtual memory; and the use of multiple
processors.
The expectations for the fifth generation systems seem to
require that substantially new architectures be evolved, and that both
hardware and software be freed from the limitations of the von
Neumann architecture.
