Hi!

I am looking for something like or exactly that. A hash function.

There are many (about 3000) groups of data (3 bytes long) that will be stored in EEPROM and would like to search very fast. If serially search a PIC with 8MHz clock would do about 8 seconds. Since the system is going to operate a parking bar, this time is too long.

So, a hash function may help store and retrieve the group of data almost immediatly.

Do anyone have any infos about it?

Regards,
Ioannis
