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.

Claims

1-17. -17. (canceled)

18. A method comprising:

accessing an access profile, wherein said access profile is associated with a characteristic of a data block and said access profile includes a rate of compression and a compression ratio; and

compressing said data block, to provide a compressed data block, based on said rate of compression and said compression ratio included in said access profile.

19. The method of claim 18, further comprising storing said compressed data block to a storage device.
