NOTE: Filter not realizable.
DECIMATE
Intersil provides a development system which assists the
design engineer to utilizing this filter. The DECIMATE
software package provides the user with both filter design
and simulation environments for filter evaluation and design.
These tools are integrated within one standard DSP CAD
environment, The Athena Group's Monarch Professional
DSP Software package.
The software package is designed specifically for the DDF. It
provides all the filter design software for this proprietary
architecture. It provides a user-friendly menu driven interface
to allow the user to input system level filter requirements. It
provides the frequency response curves and a data flow
simulation of the specified filter design (Figure 15). It also
creates all the information necessary to program the DDF,
including a PROM file for programming the control registers.
