Abstract:
An entertainment apparatus comprising:means for driving a recording medium;a main central processing unit (CPU);a first vector processing engine;a second vector processing engine;a main memory;a graphical processing unit interface;a graphical processing unit connected to said graphical processing unit interface; anda bus network comprising a main bus, a sub-bus and a sub-bus interface, said bus network for connecting said means for driving a recording medium, said main CPU, said first vector processing engine, said second vector processing unit, said main memory and said graphical processing unit interface to one another, whereinsaid main CPU is adapted to retrieve from a recording medium in said means for driving a recording medium application programs/data stored therein and to store said application programs/data in said main memory;said main CPU generates a first polygon definition information from data of a 3-dimensional object read from said recording medium in conjunction with said first vector processing engine, and provides said first polygon definition information to said main memory;said second vector processing engine generates a second polygon definition information and provides said information to said graphic processing unit interface;said graphic processing unit interface arbitrates data transfer of data including said first polygon definition information received from said main memory via said main bus and data including said second polygon definition information received from said second vector processing engine, by adjusting processing timing under the control of said main CPU such that said data will not mutually collide while transferring said data to said graphic processing unit.
