usage of arithmetic megafunctions

Thank you for your replies.

I have to implement an algorithm having too many calculations and matrix operations. Implementation exceeds the limitation on LE's and Embedded Multipliers if i use another MegaFunction for each arithmetic operation. So i tried to implement the algorithm with using a few MF's. But some equations have (for example) 2 multiplier some others have 5 multiplier. For example consequtive 4 equations need 2 multipliers:mult1,mult2 and the 5th equation need 4 multiplier:mult1,mult2,mult3,mult4. in this case the compiler returns an error such as unacceptable time delay for mult3 and mult4. Due to the such errors, i have used state machine structure to avoid exceedance of the limitations on embedded multipliers and logical elements.

Now i'm trying to learn what is the best or most suitable way for such implementation. since i'm beginner i have been looking forward to find an example code but i still couldn't find. I wil be so happy if you give advices acording to the details given above.
