ZLIB Coding Functions

This section describes Intel IPP data compression functions that implement compression methods and data formats defined by the following specifications: [RFC1950], [RFC1951], and [RFC1952]. These formats are also known as ZLIB, DEFLATE, and GZIP, respectively.
A basic algorithm for these data compression methods is based on the Lempel-Ziv (LZ77) [Ziv77] dictionary-based compression.
The structure of ZLIB data is schematically shown in Figure
"ZLIB Data Structure"

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
