High speed data compression

A new data compression system now has the ability to compress data at no less than 10 times that of any other compression system currently available. Its landmark feature means that it is also the first Internet Protocol compression system in the world.
High speed data compression
During the 1970's data compression methods were developed, on the grounds of the Lempel-Ziv (LZ) coding system that became the most commonly used. Today the LZ method has many variations, but all of them may not compete with the data compression system that has been developed in Latvia.

Data compression systems use algorithms whereby the coding employs a free-parse method. This new system simplifies that procedure much further and as a result it is much faster - in fact it can compress data streams at a rate of 1Gbit/second.

Because of the ultra-fast data compression, this system also has a very high compression rate, possesses simple hardware implementation, is super-symmetric and has small memory requirements. For the hardware version it has a predictable compression/decompression time and for the software version a good/worst-case compression time.

Apart from these unique technological advances, it has extremely low power consumption, does not require advanced chips, is suitable for mobile and embedded devices and is ultimately very cheap to use. Other benefits include simultaneous compression and acceleration for storage devices and networks, and it has thousands of different algorithms for any special requirement.

The developers have already used this system for Palm OS handheld computers and smart phones. Also, the third quarter of 2003 will see the release of a Very high-speed integrated circuit Hardware Description Language (VHDL) library for compression processors or other hardware implementations.

Today's accelerated technology married with that of tomorrow should permit this system to get smaller, faster and cheaper. This should therefore permit mankind to realise the compression rate benefits once only dreamed of.
