Techniques for decoding the run_before fields in a CAVLC encoded bitstream for H.264 are disclosed. In one aspect, the codewords corresponding to a plurality of consecutive initial zero-value run_before codewords are stored in a look-up table, allowing the decoding of such a plurality of run_before codewords in a single computation cycle. In another aspect, the look-up table is additionally configured to decode the next non-zero run_before value after the initial zero-value run_before codewords in the same computation cycle.
