[sdiy] Ultimate DSP

[Michael Boracci]

How interesting. Isn't it true that photons are just electrons on crack? In
the end what property of light allows this thing to be faster? I have been
trying to find a new use for lasers for a while and without using FM and
selective filtering to allow for high data density transmissions you still
have the properties of copper but with additional losses in the interfacing.
They are using AM apparently and that means a lot of extra quantizing to
pick out the data.

In terms of this unit I think you are totally correct. It will go the way of
acid washed denim.

It is a one-trick-pony, just doing matrix multiplications. Great if
your world consists of just matrices. There have been at least three
attempts at commercializing dedicated matrix machines with similar
claims to achievable speedups over general purpose or digital signal
processors (at their respective) and similar relative price points and
they all failed. Interestingly enough I seem to remember that this
particular optical concept was first peddled towards the 10-GBit packet
routing market, which almost disappeared overnight.
