4.6.2.1 void init_decomp_dictionary ( )

Funcion que inicializa el diccionario para la descompresion

init_decomp_dictionary

Function Description: Initialize the LZW dictionary for decompression.

Revision History: 25 Oct 2006 Chris Sadler Initial Release

4.6.2.2 void init_dictionary ( )

Funcion que inicializa el diccionario para la compresion

init_dictionary

Function Description: Initialize the LZW dictionary.

Revision History: 25 Oct 2006 Chris Sadler Initial Release

4.6.2.3 unsigned int slzw_compress ( unsigned int in_filesize, unsigned char mini_cache_size )

Function Description: Compress data with the S-LZW-MC compression technique. This differs slightlyfrom the code I used in the paper since it assumes that the data block is in RAM rather than in flash. Also,the code now embeds the size of the mini-cache in the first byte of the compressed stream so that thedecompressor does not need to know ahead of time.

This function looks for the input data in the variable "write_buffer".

Inputs:

• in_filesize - Size of the file to compress

• mini_cache_size - Number of entries in the mini-cache. Irrelevant if USE_MINICACHE is notdefined

Expected Inputs:

• The data should be in write_buffer

Outputs:

• Returns the compressed size

• Compressed data is in lzw_output_file_buffer

Revision History: 25 Oct 2006 Chris Sadler Initial Release 10 Mar 2007 Dirk Buijsman Patched bug relatedto adding the last dictionary entry to the mini-cache 10 Mar 2007 Chris Sadler If the post-compression datasize is actually larger than the pre-compression data size, this code now reverts back to the pre-compressiondata and signifies this by making the mini-cache size 0.

4.6.2.4 unsigned int slzw_decompress ( unsigned int in_filesize )

slzw_decompress



Function Description: Decompress data that we compressed. The mini-cache size is embedded in the firstcharacter of the compressed stream, so we do not need to pass it in as an entry here. We don’t spend muchtime on this algorithm in the paper, so it has not been tested as thoroughly as the compress function, but ithas worked for me so far.

Inputs:


Expected Inputs:

• The data should be in lzw_output_file_buffer

Outputs:


• Decompressed data is in write_buffer

Revision History: 25 Oct 2006 Chris Sadler Initial Release 10 Mar 2007 Dirk Buijsman Patched bugrelated to adding the last dictionary entry to the mini-cache 10 Mar 2007 Chris Sadler Handles the casewhere the compressor reverts back to the uncompressed data because the compression had resulted in adata expansion.
