Missing arithmetic instructions in Tyler and SSE. How are operations done?

I looked at the Tilera Instruction Set and noticed that it only adds, subtracts, multiplies, divides and shifts. No mention of roots, forces, logs, etc.

I also noticed that SSE (in all cases) does not contain the instructions mentioned above.

Both Tilera and SSE are designed for math-based processing such as video encoding, so I was curious.

How to perform one of these operations in such cases (Tilera and SSE [excluding ordinary scalar operations])?
