PROBLEM TO BE SOLVED: To provide an image processor which reduces power consumption drastically. SOLUTION: This graphic arithmetic unit simultaneously performs an operation of plural pixels to represent a prescribed shape to be shown on a display with combination of unit diagrams and performs processing by using an operation result about pixels located in the unit diagrams that are processing objects as what is effective. In such a time, the effectiveness of respectively corresponding val data S2201 to 2208 is decided by clock enablers 2101 to 2158 in operation subblocks 2001 to 2058 , only subblocks in which corresponding val data shows effectiveness execute an operation and the operation subblocks which are not in that way do not perform an operation. Operation blocks 200 to 205 realize pipeline processing. |
