PC BUS INTERFACE

The evaulation system provides a complete environment
for the development of high performance digital filtering and
signal generation systems. The development system is based
on the powerful Mitel Semiconductor's PDSP16350 and
PDSP16256 digital signal processing components and
comprises the following elements:

■ An IBM PC compatible board for high performance digital

filtering and signal generation

■ A powerful digital filter design software package optimised

to the specific characteristics of the PDSP16256

programmable FIR filter

■ A flexible digital filter development software package

enabling the board to be configured and operated in a wide

range of modes

■ Comprehensive supporting documentation

These facilities constitute an easy-to-use development
tool for digital filtering systems requiring sample rates of up to
20MHz and provide an ideal environment for rapidly
evaluating the capabilities of these high performance Mitel
Semiconductor devices.

APPLICATIONS
