High performance renormalization for binary arithmetic video coding

During high performance renormalization for video encoding, renormalization may involve detecting a leading number of '0's in a range value of an input stream of symbols, a run of '1's in an offset value of the input stream of symbols, and a run of '0's following the run of '1'in the offset value. A bitstream may be outputted based on an iteration window for a number of renormalization iterations. The iteration window may comprise a bit range after the run of '1's in the offset value, and the number of renormalization iterations may be based on the leading number of '0's in the range value. A run of '1's followed by one or more '0's may be identified as a particular pattern.
