Abstract
Description
technical field
[0001] The present invention relates generally to the fields of data compression and data compaction. More specifically, the present invention relates to an apparatus and method for compacting compressed and uncompressed data blocks into an output buffer. The invention also relates to a device and a method capable of reducing the wasted space of a storage medium in the case of storing compressed data blocks or the like. Background technique
[0002] Lossless data compression is one of the commonly used algorithms in All-Flash-Array storage devices. When data is written to a storage device, data compression reduces the size of the stored data. In addition, when the compressed data blocks are read from the storage device, these compressed data blocks are decompressed to the original content and size. In primary storage, data compression and decompression is done transparently "in-line / on-the-fly" to applications writing and reading data.
[0003] Also, loss...
