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. 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.
