|
This example uses two buffers of size a little more than
|
|
(1 << CONFIG_SYSTEM_LZF_BLOG) to compress and decompress data in
|
|
chunks. Slightly better compression should be obtainable with larger
|
|
chunks.
|
|
|
|
NOTE: This is a static memory allocation and will take add a little
|
|
more than 2 * (1 << CONFIG_SYSTEM_LZF_BLOG) bytes to the size of the
|
|
.bss section used by the program.
|
|
|
|
NOTE: This represents a maximum blocksize. The use may select a
|
|
smaller blocksize using the 'lzf -b' option.
