Abstract

A method includes executing, at a processor, a dedicated arithmetic encoding instruction. The dedicated arithmetic encoding instruction accepts a plurality of inputs including a first range, a first offset, and a first state and produces one or more outputs based on the plurality of inputs. The method also includes storing a second state, realigning the first range to produce a second range, and realigning the first offset to produce a second offset based on the one or more outputs of the dedicated arithmetic encoding instruction.
