Abstract:
A data compression method, comprising the steps of:receiving a plurality of uncompressed data sets as input;selecting a portion of each uncompressed data set;vector compressing the selected portions collectively, using a vector compression technique, to form vector compressed data when the data in the selected portions is related for each data set;planar compressing the selected portions independently if the selected portions cannot be compressed collectively, using a planar compression technique, to form planar compressed data for each of the selected portions;storing vector compressed data, resulting from said step of vector compressing, in a vector data memory storage area; andstoring planar compressed data, resulting from said step of planar compressing, in a plurality of planar data memory storage areas such that each one of the planar storage areas stores planar compressed data corresponding to one of the uncompressed data sets.
