12 QATzip is a user space library which builds on top of the Intel Quick‐
13 Assist Technology user space library, to provide extended accelerated
14 compression and decompression services by offloading the actual com‐
15 pression and decompression request(s) to the Intel Chipset Series.
16 QATzip produces data using the standard gzip format (RFC1952) with ex‐
17 tended headers. The data can be decompressed with a compliant gzip im‐
18 plementation. QATzip is design to take full advantage of the perfor‐
19 mance provided by Intel® QuickAssist Technology.
