High speed variable length decoder |
摘要 |
A high speed variable length decoder can decode more than one code word in one cycle. A PLA used in the decoder includes extra product lines and extra output lines in order to detect and decode two successive short length code words in one cycle. When two short length code words are detected, a corresponding extra product line is activated and the two code words are decoded in the same cycle using an extra output line. For a digital video compression system, a significant speed-up in the variable length decoder can be achieved by the invention.
