The navtec GmbH has developed a quintuple
DSP board for PCs with ISA/EISA bus. The main application for this plug-in
is fast signal processing. It can also be used as a co-processors for PCs.
There is an optical AES/EBU interface included on the board as well. That
makes the Quint56 board predestined to be used for problem solutions in
audio signal processing with calculating time-intensive algorithms.
|The board was designed as a long plug-in
card. The serial interface signals of the first DSP are led out of the
PC alongside its mounting edge. That is also where the optical in- and
As this board is often used in research and training, all processors are equipped with sockets. This makes it easy to exchange DSPs in the SMD housing (PQFP).
