High-Performance Printer Display Processor
General Description
The NS32CG16 is a 32-bit microprocessor in the Series
32000 EP^TM family that provides special features for graph-
ics applications It is specifically designed to support page
oriented printing technologies such as Laser LCS LED
Ion-Deposition and InkJet
The NS32CG16 provides a 16 Mbyte linear address space
and a 16-bit external data bus It also has a 32-bit ALU an
eight-byte prefetch queue and a slave processor interface
The capabilities of the NS32CG16 can be expanded by us-
ing an external floating point unit which interfaces to the
NS32CG16 as a slave processor This combination pro-
vides optimal support for outline character fonts
The NS32CG16’s highly efficient architecture in addition to
the built-in capabilities for supporting BITBLT (BIT-aligned
BLock Transfer) operations and other special graphics func-
tions make the device the ideal choice to handle a variety
of page description languages such as Postscript^TM and
PCL^TM
