Abstract
Data compression and decompression methods for compressing and decompressing data based on an actual or expected throughput (bandwidth) of a system. In one embodiment, a controller tracks and monitors the throughput (data storage and retrieval) of a data compression system and generates control signals to enable/disable different compression algorithms when, e.g., a bottleneck occurs so as to increase the throughput and eliminate the bottleneck.
Claims8
A method comprising:
- compressing data using a compression routine providing a first compression rate;
- tracking throughput of a data processing system to determine if the first compression rate provides a throughput that meets a predetermined throughput threshold;
- and
- if the tracked throughput does not meet the predetermined throughput threshold, compressing data using a compression routine providing a second compression rate that is different from the first compression rate, to change the throughput of the data processing system.

A method comprising:
- using an asymmetric compression algorithm to compress data at a first compression rate to provide first compressed data to a communications channel;
- tracking throughput of the communications channel;
- determining if the first compression rate provides throughput that meets a predetermined throughput threshold;
