The big demand right now for reverse-engineering-resistant ASIC's
with embedded algorithms comes from the financial engineering
sector -- quant trading, high-frequency trading, and so forth.

Well. You guessed it. I wasn't going to mention it, but since you
brought it up....

We want to embed an algorithm originally developed for financial
trading into a DSP chip, for "stochastic time series" applications
such as medical monitoring devices, adaptive optics, weather
prediction, and other useful things. Used privately for financial
trading, it can be maintained as a trade secret known only to its
inventor and a couple trusted people. Once embedded into electronic
hardware, however, it becomes a target exactly like you describe,
regardless of how far removed the end application appears to be from
finance.

I'd bet a nickle the OP is looking at something along these lines.

Heh. Where do I send your nickel?

And getting back to my original question, is it pointless to search
for a secure DSP that fits my needs?
