[pci] 32 Channel Audio In/Out PCI board (16bit/8kHz x32 x2)
Hi PCI-Gurus,
I will try to develop a 32 Channel PCI Audio Card.
The AD/DA converters have one serial in/out per 2 channels.
That means I will need 16 serial ports(Sin/Sout) to send/receive audio samples.
And addtional 16 serial ports to control the input/output gain(not shown in
diagramm).

Could you please give me a hint which device I should use, and which would be
the best development board for this project. Can the opencores PCI-core used for
that or would it be better to get a MegaCore like Altera's pci_mt32.
How many man-hours would you guess for such a project.
Thanks in advance for your help,
with best regards,
Nico.
