It would be faster if it was not being copied. There are places, like the precomputed tables, that could be represented in 16 bits. There was no advantage to doing this on the TI arm chip but it might be a different result for other chips. -- Brad ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
