C and Assembly language inside the eclipse for NIOS II

Hi,

Is this possible to have combination of C and Assembly language inside the eclipse for NIOS II?

In Visual studio you can write your C code and add some assembly code using __asm key, is there any similar command in the eclipse for NIOS II?

I have some multiplication and division which I would like to modify its algorithm to increase the calculation speed.

Please give me some suggestion.
