Just because it's not a current product doesn't mean it doesn't exist. I 
have a DSP56361 right here on my hard drive--preliminary anyway, 2nd 
draft from back in March '99--and yes, it's out there in real products. 
I don't recall what the difference was between it and the '362, but it 
wasn't much, and the OP can probably use the '362 manual. Another thing 
to remember about chips is that manufacturers often continue to sell 
them for years to existing customers after removing them from their 
current product offering ("end of life").

I'd rather trust the chip manufacturer than somebody else (even Google)
which products they have in their portfolio :-)

thanks for your reply.

If you do a google search for "dsp56361" you will see it is referenced
with linux drivers for pci audio cards. Further, there is generic
driver code from Echo which explicitly mentions this DSP, it is sure no
typo.

As I couldnt find any info, I was just curious what might be special
about this DSP.

The DSP56361 does not exist. Please look exactly if the named DSP on
the Indigo I/O is a DSP56301. This would make sense since the '301 has
a PCI interface that is useful for this application. The '362 is the
first derivative of the '36x symphony series (designed especially for
audio apps - they have an additional audio autput (DAX) that can be
configured for AES3 or SP/DIF). This series will be probably replaced
by the '37x series in the future. Nevertheless - the probability that
the Indigo uses the DSP56371 is zero since this device is lacking the
PCI interface.

The '37x are lacking an external memory bus (external memory can be
only interfaced by SPI/I2C) but have an additional filter coprocessor
that is very useful for audio.

One final question: Why do you ask this? Do you want to design your own
hardware? Do you think it makes any difference to the end user which
DSP derivative is desiged in this interface? The DSP core is absolutely
identical with all DSP563xx derivatives - for this reason they are also
object code compatible. The only difference is in the number and kind
of interfaces that adapts them to the desired application.

Hope this helps

Hi All,
for the sound card Indigo I/O from EchoAudio I found some reference
that it is using the DSP56361. But I cant find any info about this dsp.
Can anyone tell the difference to the DSP56362 ?
Thanks!
