| 发明名称 | Hardware compression using common portions of data | ||
| 摘要 | Methods and devices are provided for data compression. Data compression can include receiving a plurality of data chunks, sampling at least some of the plurality of data chunks extracting a common portion from a number of the plurality of data chunks based on the sampling, and storing a remainder of the plurality of data chunks in memory. | ||

| 主权项 | 1. A method for data compression, comprising: receiving a plurality of data chunks; sampling at least some of the plurality of data chunks using hardware logic; extracting a common portion from a number of the plurality of data chunks based on the sampling using hardware logic; storing one copy of the common portion; and storing a remainder for each of the plurality of data chunks as compressed data, wherein the remainder does not comprise the common portion. | ||
