Abstract
A data processing scheme capable of realizing both the reduction of an amount of data due to the compression and the shortening of a time required to refer to data, as well as the lowering of the power consumption in a portable information device. A compression start position is detected, and data subsequent to the compression start position are compressed, and then a data sequence is generated from data prior to the compression start position and subsequent compressed data. In a case of reading a data sequence containing non-compressed data and subsequent compressed data, a boundary position between the non-compressed data and the compressed data is detected, and only the compressed data subsequent to the boundary position is expanded. In a case of reading data sequence containing compressed data in at least two segments which are separately compressed, only the compressed data in a top segment are expanded, and a data sequence is generated from expanded top segment data and compressed data in subsequent segments.
