Abstract
A scheme for compression of large sets of short blocks of data for storage in a storage medium, such as a read-only memory. Applications of the scheme include compression of fonts for printers, ROM disks in portable PCs, and others. These applications require random access to individual blocks, and fast, real-time decompression. The scheme applies an asymmetrical three-stage methodology in which a first stage provides training and optimization for a set of data blocks; a second stage effects data compression; and a third stage effects data decompression.
