A floating point DSP, as noted.

What's the canonical method of doing this? Taylor series
approximations?

Or CORDIC.

Yes, Cordic is a good alternative. It is especially competitive if
floating point operations have a high latency (or are emulated).
You can also control accuracy so that the answers are within
1 ULP - this is pretty much impossible when using floating
point operations of the same precision as the result precision.
