Special Parameters

The LZO coding initialization functions have a special parameter
method
. This parameter specifies level of parallelization and generic LZO compatibility to be used in the LZO encoding. The table below lists possible values of the
method
parameter and their meanings.
Parameter
method
for the LZO Compression Functions
Value
Descriptions
IppLZO1XST
The compression and decompression are performed sequentially in a single-thread mode with full binary compatibility with generic LZO libraries and applications.
IppLZO1XMT
The compression and decompression are performed in parallel (multi-threaded mode), it is more fast, but not compatible with the generic LZO.
IppLZO1X1ST
The compression and decompression are performed sequentially in a single-threaded mode with full binary compatibility with generic LZO libraries and applications.
The compression ratio of this method corresponds to the LZO
lzo1x_1_compress
function (default function for the
lzop
compressor). The
IppLZO1X1ST
method provides lower compression ratio than
IppLZO1XST
but better compression performance.

Product and Performance Information

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.
