How does a CONERT TOOL WORK IN SYSTEM GENERATOR?

How does a "Convert" tool work in system generator.?

When i use a FIR filter, the number of output bits are more than the input bits.

Inorder to maintain a constant bit transfer, i thought of using a convert tool.

But i dont know, how that tool is gonna work?

Can any one please tell me, what exactly happens inside that "convert" tool?

It's easiest to just use the settings of the FIR block to do your output truncation/rounding

Hi sir,

what i want is, what is the mechanism inside the convert tool,  which converts a 34 bit with zero fractional part , into, a 18 bit , 16 bit fractional part??

The magnitude varies a lot.

The  FIR compiler v5.0 does not accept input more than 34 bit.

What if we need to give an input more than 32? 

I thought of converting a 44 bit into 34 bit , inorder to give a input to a FIR. But, the magnitude of the original input changes.

what to do?
