Abstract

PURPOSE: To speed up graphic processing without using a large capacity storage device by enabling read in a direction different from a data input direction. CONSTITUTION: A memory array M-AR consisting of respective memory cells having two ports when supplied with a read address RA has one memory row and one memory column each selected by a selecting circuit SEL and held data can be read out longitudinally and laterally at the same time. Then one of the 4-byte data which is read out longitudinally and 4-byte data which is read out laterally is outputted as read data through selectors S0 -S3 which are controlled with a control signal H/V. Thus, by reading out graphic data which is inputted from an X direction from a Y direction it is possible to easily rotate the graphic by 90 deg.. Consequently, the graphic processing can be performed in real time without performing many complicated operations.
