ABSTRACT:
An extended graphics array (XGA) graphics system is disclosed for converting data received in a double storage bank into a single storage bank when the data is processed. The system includes a graphics data generator for generating synchronizing signals and a main clock signal according to an XGA graphics mode and dividing pixel data to be displayed on a display into even and odd-number data when transmitted from the graphics data generator. It also includes a driving unit having two storage units for storing a predetermined number N of pixel data and for driving the display according to the pixel data stored in the storage units. Connected between the graphics data generator and the driving unit is an interface unit, which includes a plurality of flip-flops, for sequentially arranging the even and odd-number data according to the N pixel data which are to be stored in the storage units, in which the data is arranged based on control signals which are generated by dividing the frequency of the main clock by two and then outputting the sequentially arranged N pixel data to the two storage units, thereby interfacing the graphics data generator with the driving unit. The control signals include carry signals generated by the graphics data generator, the use of which reduces electromagnetic interference (EMI) by employing a lower frequency than the main clock. Further, the number of flip-flops required is fewer than is conventionally used when a shift-register is employed.
