Really? I think a standard series (no Schottky etc.) 7486 had a propagation delay around 7 ns. I think you could beat this with a 200 Mhz CPU, since an XOR operation will be handled within one clock tick when the operands are in registers. ;-) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
