Query: Data Compaction - Compression without Decompression   Data compaction is a new approach for lossless and lossy compression of
read-only array data. The biggest advantage over existing approaches is the
possibility to access compressed data without any decompression. This makes
data compaction most suitable for systems that could currently not apply
compression techniques due to real-time or memory constraints. This is true for
the majority of all computers, i.e. a wide range of embedded systems.
