Re: Best processors for trig?

Hi - I was just wondering, are there any processors out there that
have been optimized for trig operations? I'm hoping to find a
processor that can do trig ops (sin, cos, tan, asin, acos, atan, etc.)
quickly. The faster the better. I would really like to be able to do
such operations in the single digit microsecond range or less, though
that's probably a longshot. I'm looking for floating point values -
ideally in the C data type "double". Does anything like this exist?
Ideally in a non-BGA package, as I hate debugging the little buggers.

Thanks!

-Mike


The AT572D740 has an ARM + a floating point DSP
capable of 400 floating point MACs per us.
It uses 40 bit floating point representation.

Should probably be enough.
You can get a PMC module if you dont like the BGA package.
