Imaging Signal Processor
General Description
The NS32FX16 is a high-performance 32-bit member of the
Series 32000 EPTM family of National’s Embedded System
ProcessorsTM specifically optimized for CCITT Group 2 and
Group 3 Facsimile Applications Data Modems Voice Mail
Systems Laser Printers or any combination of the above
It can perform all the computations and control functions
required for a stand-alone Fax system a PC add-in Fax
Data Modem card or a Laser Fax system
It also meets the performance requirements to implement
9600 and 7200 bps modems complying with CCITT V 29
and V 27 standards
The NS32FX16 provides a 16 Mbyte Linear external ad-
dress space and a 16-bit external data bus
The CPU core which is the same as that of the NS32CG16
incorporates a 32-bit ALU and instruction pipeline and an
8-byte prefetch queue
Also integrated on-chip with the CPU are a DSP Module and
a 384-byte RAM Array The DSP Module executes vector
operations on complex variables and is specially designed
to enhance performance in modem applications The vector
operations can also be used to efficiently implement FIR
Filters and other DSP primitives The on-chip RAM Array is
used to store the coefficients of the various filters and can
be accessed by both the CPU and the DSP Module
The NS32FX16 capabilities can be expanded by using an
external floating point unit (FPU) which directly interfaces to
the NS32FX16 using the slave protocol The CPU-FPU clus-
ter features high speed execution of the floating-point in-
structions
The NS32FX16 highly-efficient architecture combined with
the NS32CG16 graphics instructions and the high-perform-
ance vector operation capability makes the device the ideal
choice for PostscriptTM and Fax applications
