Ricoh Launches new Compression technology

Ricoh (Menlo Park CA.) has enhanced the DCT algorithm making it 30
times faster than JPEG implementations.  The software running on a
MacIIfx (40mhz 030) compressed a 768kbyte 24 bit image 25-1 in 3.5
seconds.  The program manager said that an 040 would cut the
compression to less than a second which is near the time currently
offered by chip-based implemetations.  Ricoh is at work on a
chip-based implementation that will offer realtime performance.  Ricoh
plans to license both software and chip to developers starting this
summer.
