A context-based adaptive binary arithmetic coding (CABAC) method. The CABAC method for a bitstream comprises: detecting a control signal (Sig_first); decoding a first bin representing one of a first coefficient flag (Sig) and a second coefficient flag (Last) from the bitstream according to the control signal (Sig_first); decoding a second bin representing one of the second coefficient flag (Last) and a next first coefficient flag (Sig) from the bitstream according to the decoded first bin and the control signal (Sig_first); and updating the control signal (Sig_first) according to the decoded first and second bins. The first and second bins are decoded in one clock cycle, the first coefficient flag (Sig) indicates whether a corresponding coefficient value is zero, and the second coefficient flag (Last) indicates whether a coefficient map decoding process is finished. |
