Short vs Int vs Floating Point usage in Kernels

In the optimization guide there is a section on fixed point operation, page 14, which suggests statically masking your 32-bit integers to the desired precision. If I understood this right, the AOC would be able to disregard the extra bits during hardware generation thus will reduce the amount of logic (minimal in this case) but still a reduction. You may want to look into that and see if it helps you out any. I was curious so I ran the example listed in the guide for 17-bit precision. I had an increase in logic for the fixed point version over the straight 32-bit version and I don't think this should be the case. I wouldn't think the load/store units that access the memory wouldn't be an issue as Outku suggested in the case of the original poster. Any insight would be appreciated.
