Compression is addressed in hardware just as well as in software. This topic covers implementations of compression in chips, devices, etc.
Parallel Implementation of Data Compression Technologies for Multi-Gbit/s Networks
This group at Loughborough University in the UK would like to use sophisticated compression techniques in high speed networks. To make it all happen, they need to do it in hardware, and do it in parallel. This page has information about their efforts, along with links to papers and other information.

MP3elf - Network MP3 Player
The MP3elf is a low-cost Ethernet connected MP3 player that receives a MP3 stream from a local area network server and delivers it to amplified speakers or a Hi-Fi system. You can have a single source of MP3 files in your home or office, and browse through playlists from any MP3elf. The Universal IR receiver allows the MP3elf to respond to one of your existing Remote Controls (or use the on-board pushbuttons) and the LCD interface can display your very own choice of information. The elfServer software design allows compatibility with a range of different front-end options. As it is Java based, it can run on Windows, Macintosh, or Linux machines.
XCode Video Networking Processor
ViXS Systems from Toronto, Ontario has announced the
XCode chip, which they say will adjust MPEG formats, bit rates, and
resolutions on the fly as data moves through an IP network. At a
minimum, this means the part can format MPEG1 to MPEG2 to MPEG4, and change resolutions from QCIF to standard to high definition and back again, depending on network bandwidth availability.

WIS Technologies announces PC Video chip
EE Times carries this announcement of a new PC video encoder chip from WIS Technologies. The chip is designed to do the heavy lifting that is real trouble for a host CPU, by taking care of things like DCTs and motion estimation. It relies on that same host CPU to do format conversion and other more mundane tasks. The chip currently supports video formats that include DiVX, H.261, H.263, MPEG-2, and more

GEMAC
This company sells an IP core that performs lossless data compression. Not sure what algorithm they are using, it is described as “GEMAC’s data compression algorithm.” This algorithm was first published at DCC ‘95, and is described as a hybrid of ZL1 and ZL2, created with the goal of maximizing compression rate.
STMicro and 8×8 to team on video chips
EE Times reports that Europe’s ST Microelectronics is teaming up with 8X8 Inc. to produce chips aimed at the IP Telephony market. They are hoping to create chips that will be used in network video applications.8X8 will be supplying advanced compression and decompression algorithms for the chip vendor to sell in silicon.

Privately held Pulsent is promising a new video compression technique that can stream video across the net with only half the bandwidth of MPEG2. They’ve not only created a new algorithm but are also developing the chips to support it.
Hi/fn, Inc.
Hi/fn makes lossless compression hardware and software. They have a bunch of chips that implement LZS and MPCC compression, plus a library that does the same thing. I have been led to believe that these algorithms are partially or completely protected by patents.

RICAZip.com
RICAZip.com has proprietary lossless image compression technology called RICA (Reversible Image Compression Algorithm). RICA retains original file formats (e.g. TIFF, DICOM, BMP, TGA, PGM etc.). RICACom says We have yet to find any method that provides better compression ratios (for truly lossless), including wavelet. On a PII 450MHz RICA compresses @ 6MB per second and decompresses at 12MB per second.
Available as a standalone image archive app, Adobe Photoshop Plugin, Browser Plugin, and RICA SDK.
DCL reader Karen H. says: Evaluation of this product demonstates excellent compression ratios and it is also very fast compared to other methods I have used.
Nancy codec to give MPEG-4 a run for its money
Nancy is the name of a lightweight video codec being used to send video email in the J-Phone design in Japan. The proprietary algorithm uses something called the Structured Meta Scale Polygon to compress data with fewer MIPS than its competition. Nancy can compress and decompress 30 fps at QCIF resolution with as little as 50 MIPS, using on ly 30-49Kbytes of memory.
