PCI boards embedding DSPs exist. However, they are not very cheap, because : - they require PCI glue (FPGA, or some sort of bridge chipset). DSPs usually can't be directly connected to the PCI bus. They probably also need some RAM, or a more complex CPU to drive them. - such existing board usually provide some kind of PCM highways, and/or switch matrices to connect to the telecom environnement - this is a small market : this drives prices up quite fast. > hardware assisted DSP functions as well as patent indemnification. > Would you even have to USE the DPSs in order to be patent indemnified? Err, I don't see the point with patent indemnification. The price you pay for the patent depends on which patents (ie, which algorithms) you use. Unless your board is limited (by firmware, for instance), to a certain set of algorithms, you can't include the price of the algorithm in the board. -- Nicolas Bougues Axialys Interactive _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
