In the firewire case not modification in the computer would be needed (beside putting a comercial firewire card into it ...), the DSP would be int the breakout-box, including the ADDA Converter: PC <-> PCI-Bus <-> Firewire-Card <- Cable #### our box #### Cable -> Firewire IO Chip (if not available in a DSP) <-> DSP <-> ADDA Converters ok. the our-boy side is much more complex. Only the first idea post ;-) It would be s.th. like: Firewire ^ | Mem <-> DSP | ADDA-Converter Here are still very many different possibilities how to connect the Firewire port and the ADDA-converters exactly. Also some general purpose 32bit �C might be better to _crunch_ all the data and let a DSP only compute the (custom) effects ... > CU > Pieter k33p h4ck1n6 Ren� -- Ren� Rebe (Registered Linux user: #248718 <http://counter.li.org>) eMail: [EMAIL PROTECTED] [EMAIL PROTECTED] Homepage: http://drocklinux.dyndns.org/rene/ Anyone sending unwanted advertising e-mail to this address will be charged $25 for network traffic and computing time.
