The runtime control register map for the scaler is given on page A-19 of the user guide. The general description of avalon slave interfaces is given on page 4-14.

and input width and height as 32x32 using the control packet but the problem is the core is not discarding the extra data if i gave more than 1024 pixels and the output is same size as the input

This concerns me, why do you have "extra data". The length of the video packet should match exactly what's specified in the control packet. Where is the "extra data" coming from? Who is creating the control packets?

The biggest problem I've seen so far that people have had with the VIP suite is not that the cores aren't working but that they misunderstand how the entire video system must be architected.
