Sample Code - Huffman Decoder Author: Arkon Category: Code Crunching File Name: hdecode.asm File Size: ~ 5.06KB Uploaded at: 15-Aug-03 Downloads: 1575 Description:   Tiny program which extracts Huffman data block and prints it. User Contributed Comments(2)  [1] bitRAKE | 2008-01-06 02:06:51 How about 23 bytes? start:   mov bx,root   mov cx,last_data_bit read_bit:   bt [si],cx   adc al,node_0-root   xlatb   or al,al   jns c   xlatb   int $29   salc c: loopne read_bit x: ret Can save a few bits if data matches code or tree. I remember reading of a 19 byte decompressor, but I cannot find reference to it...will need to be re-discovered... (c:  [2] arkon | 2008-01-11 17:53:26 the bt instructions rocks cause you can access the memory as a long stream, thus you don't need to inc si every time like i did. very nice improvement. but now i need to reverse the data, anyways when i have some time for this i will change the code. btw - the drawback is that it only supports 7 bit symbols, could be ownage to support 8 bits symbols so it can extract code as well.
