<P>PROBLEM TO BE SOLVED: To provide a low power memory hierarchy for a high performance video processor. <P>SOLUTION: An apparatus generally having an internal memory and an external transfer circuit is disclosed. The internal memory may be disposed on a chip and may contain at least one first buffer for storing a subset of at least one reference frame (i) suitable for motion compensation and (ii) stored in an external memory off the chip. A size of the at least one first buffer generally exceeds one row of blocks in the reference frame. The external transfer circuit may be disposed on the chip and configured to transfer the subset from the external memory to the internal memory. <P>COPYRIGHT: (C)2013,JPO&INPIT |
