Summary: NCR/32 chips set information


The NCR 32 bit chip set is used by NCR in a few of our larger machines,
such as the 9300.  Honeywell has signed some kind of licensing agreement
so that they can use the chip set.

Some general info follows, but be forewarned that my information is skimpy
and not necessarily up to date.  Perhaps some of NCR's people from the
West Coast plants will comment and correct me where I'm wrong.

The NCR/32 CPU and MMU are supposed to be available in 8Mz versions.  The
CPU is known as the "CPC" (Central Processing Chip????) and the MMU is
called the Address Translation Chip (ATC).  The other support chips are
a serial I/O controller (SIC), an math chip (EAC) - whatever that means -
(its an FPU of some kind), and a VAC - Virtual Assist Chip, that offloads
the CPC in a virtual address environment.

The CPC contains 16 general 32-bit registers and is microprogrammed externally.

More info should be available from your local sales office.  But you'll
probably have to push it.

Another development of possible interest is the GAPP chip.  It's a an array
of 72 processors on a single chip. GAPP is reportedly 10x faster than the
system it replaces, with a 8 to 1 size reduction.  The chip was designed for
Martin Marietta and will be used by them in military applications of image
processing.  NCR retains marketing rights for commercial and industrial
applications.
