Variable Length Code Decoder
The Variable Length (VL) Engine uses the code books or lookup tables to map the Huffman code
words. Huffman coding is a kind of entropy coding method used in H26X. Image or video data
size can be reduced significantly when proper Huffman tables are used. Not only the variable
length codes but also the fixed length codes can be decoded in this engine
.
Bit streams coming
from the programmable in/out port (PIO) are fed into VL engine during decoding process.
