<P>PROBLEM TO BE SOLVED: To provide a processor capable of executing filtering processing at a high speed. <P>SOLUTION: The computational unit relating to this invention is provided with a computing unit 201 for executing the filtering processing. Data supply to the computing unit 201 is performed in an internal register 100 comprising a flip-flop. Data read from the internal register 100 are output to a shift register 200 and the data are supplied to the computing unit 201 for each cycle. Also, a mechanism for changing the computing direction of a filter according to a motion vector is provided, and by executing horizontal filtering and vertical filtering by the same instruction, performance decline due to a branch instruction or the like is prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
