Abstract:
According to a coefficient variable length coding method adopting four-stage pipeline, a 3-dimension value including a run, a level and a last data is obtained by performing a run length coding upon coefficient data, where, after transferring the 3-dimension value, a variable bit vector is obtained from the transferred 3-dimension value and the variable length bit vector is stored, and where, particularly in case the pipeline breaks, the method reuses the previously obtained 3-dimension value to minimize process time such that the coefficient variable length coding is swiftly performed by the efficient pipeline operation, and the broken pipeline may be restored within minimized time.
