摘要：
To handle boundary conditions efficiently during bitstream extraction, a predetermined number of bits are extracted from the bitstream register starting from a most significant bit of the bitstream register when an underflow flag is set. The predetermined number equals a predetermined extraction width minus a previous starting position. The bits are stored in a lowest part of a destination register, and the underflow flag is cleared.
