* Ants Aasma: > CRC has exactly one hardware implementation in general purpose CPU's
I'm pretty sure that's not true. Many general purpose CPUs have CRC circuity, and there must be some which also expose them as instructions. > and Intel has a patent on the techniques they used to implement > it. The fact that AMD hasn't yet implemented this instruction shows > that this patent is non-trivial to work around. I think you're jumping to conclusions. Intel and AMD have various cross-licensing deals. AMD faces other constraints which can make implementing the instruction difficult. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
