The navtec GmbH has developed a dual-DSP
board for PC's with ISA/EISA bus. The plug-in board can be employed
as a development system for Motorola 5600X processors or as a fast signal
processing co-processor for PCs.
|As the board is often employed in research
and training, it contains two sockets. That makes it possible to
exchange DSPs in the SMD housing (PQFP and TQFP) easily.
Because of its flexiblity, navtec very often uses this board for those customer-specific solutions, where a DSP is the major component.
The mechanical dimensions allow it to employ
a standardised European card as a carrier for peripherical circuits. Put
together, the two boards have the same measurements as a long PC plug-in.
