DSP-board for PCs with five processors
(Quint56)

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.

Das Quint56-Board 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 outputs are.

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).
