Abstract
A data compression circuit has a compression mode of operation where it determines and stores minimum and maximum values of successive sequences of applied data words and provides an output comprising a pair of data words representing the stored minimum and maximum for each sequence, offset by a selected amount. The circuit also has a transparent mode of operation where output data sequences match input data sequences.
