PROBLEM TO BE SOLVED: To provide a micro processor and a picture processor, in which only one output port of a memory unit is required, the storage area of the memory unit is effectively used and a processing is facilitated. SOLUTION: A register 25 delaying picture data supplied from a memory unit 21 by one pixel data and outputting it, an arithmetic computing element 26 adding pixel data from the memory unit 21 and the register 25 and a shifter 28 outputting operation result data added in the first cycle to the memory unit 21 as it is, shifting operation result data added in the second cycle by two bits in a borrow direction and outputting it to the memory unit 21 are installed. Only one output port is required in the memory unit 21 and constitution can be simplified. |
