EFFICIENT MEMORY FETCHING FOR MOTION COMPENSATION VIDEO DECODING PROCESS

摘要

This disclosure describes efficient memory fetching techniques that can improve data fetching during a motion compensation decoding process. The techniques propose several different memory fetching modes that may be very efficient in different scenarios of the motion compensation decoding process. In some embodiments, a motion compensator selects a particular memory fetch mode from a plurality of possible modes on a case-by-case basis for the memory fetches associated with a motion compensation decoding process of a macroblock. The techniques described herein may be particularly useful when fractional interpolation to sub-integer pixels is used in the inter-frame compression.
