Hi,
Xilinx have a tool called System Generator which allows you to design DSP
functions and target hardware.
We do have a image rotation example in system generator. Visit our website
and look at the tool?

Aside from the choice of algorithms and how they match each chip's core
architecture...I'd lean towards the one whose tools you are most familiar
with. I've always heard that Xilinx is more DSP friendly than Altera but
that might have changed in the last 6-12 months.
The question is very similar to TI vs ADI DSP chips - you can't go wrong
with either one of them for 80-90% of the applications. But if you know one
set of tools better than the other, then there is a clear favorite.

I would like recommendations on which FPGA to use (Xilinx vs. Altera
vs. Actel) in an application which rotates a 640x480 real time video
frame.  I would also appreciate any pointers on rotation algorithms
that I could use for this.

Thanks in advance for all your help.
