You can: log in, read the tech support FAQ, or request your lost password. This dumb message (and those ads) will appear on every screen until you register! Get rid of this crap by registering your own SA Forums Account and joining roughly 150,000 Goons, for the one-time price of $9.95! We charge money because it costs us money per month for bills, and since we don't believe in showing ads to our users, we try to make the money back through forum registrations.

The performance concern here is that your method appears to require misaligned loads from puc. I don't know the details for x86, but most hardware hates this. You may want to consider making only aligned loads to keep 64 bits of the buffer in memory, search for the sequence within those bits, and if not found slide the 'window' forward by 32 bits.
