Abstract

Multi-cycle key compare units. A compare unit includes a comparator, additional compare logic and at least one pair of buffers which provide input to the comparator. The compare unit sorts variable length records in streaming mode without the need for complex state machines to maintain state relating to the comparing. A record may have a variable length key and optional variable length data. The record and/or the key is split into fixed, pre-defined lengths. The total key and record lengths are unknown to the comparator of the compare unit.
