DSP instruction for x*x + y*y. Does it exist?

Hello all!

I am new to ARM community and this is my first question here. I work on embedded systems where we use Cortex-M4 based MCUs (concretely STM32F3 series). I would like to ask, if there is a DSP instruction which would calculate x*x + y*y.

x and y represent sine and cosine values (signed integers, 16-bit variables are sufficient). I would like to calculate a square of amplitude (x*x + y*y).

Thanks in advance.
