16. The method of claim 15 further comprising: calculating an (i+1)-th index value for an (i+1)-th bin of the syntax element based on the variable and loading one of the context models for the (i+1)-th bin based on the (i+1)-th index value at the (i+1)-th clock cycle; encoding the (i+1)-th bin and updating the one context model related to the (i+1)-th bin at the (i+3)-th clock cycle; and generating a coded bit string for the (i+1)-th bin at an (i+4)-th clock cycle.
17. The method of claim 16 further comprising: calculating an (i+2)-th index value for an (i+2)-th bin of the syntax element based on the variable and loading one of the context models for the (i+2)-th bin based on the (i+2)-th index value at the (i+2)-th clock cycle; encoding the (i+2)-th bin and updating the one context model related to the (i+2)-th bin at the (i+4)-th clock cycle; and generating a coded bit string for the (i+2)-th bin at an (i+5)-th clock cycle.
