Abstract

A data compression apparatus including a circuit for receiving a data element, a storage circuit for sequentially storing previously received data elements at sequentially addressed fixed locations, a circuit for comparing the received data element to the stored data elements to determine whether the received data element matches at least one of the stored data elements, and a circuit for generating an address of the matching stored data element. In addition, a method of compressing data including the steps of receiving a data element, sequentially storing previously received data elements at sequentially addressed fixed locations, comparing the received data element to the stored data elements to determine whether the received data element matches at least one of the stored data elements, and generating an address of the matching stored data element.
