Abstract:
A graphic translate engine for performing a predetermined geometrical arithmetic processing with respect to vertex data of a figure stored to an external memory unit, the graphic translate engine comprising:an internal memory section divided into first and second memory blocks and capable of inputting and outputting data every memory block; a data holding section for temporarily storing one portion of said vertex data stored in said internal memory section; and an arithmetic section for receiving the vertex data stored in the data holding section and generating graphic data by performing predetermined processing of the vertex data, and outputting the graphic data to said data holding section; wherein during a period of time, the first memory block of said internal memory section is connected to said external memory unit and the second memory block thereof is connected to said data holding section and the first memory block outputs the graphic data to said external memory unit and then receives the vertex data from said external memory unit while the second memory block outputs the vertex data to said data holding section and then receives the graphic data from said data holding section, wherein, during a succeeding period of time, the first memory block is connected to said data holding section and the second memory block is connected to said external memory unit and the second memory block outputs the graphic data to said external memory unit and then receives the vertex data from said external memory unit while the first memory block outputs the vertex data to said data holding section and then receives the graphic data from said data holding section, and wherein the alternative connection is repeated.
