ABSTRACT:
A highly integrated, single chip computer system having not only a central-processing unit (CPU) but also specialized coprocessors. The specialized coprocessors, for example, enable the single chip computer system to be reasonably sized, yet perform high quality video (e.g., MPEG-2) and graphics operations (e.g., three-dimensional graphics). The single chip computer system offers improved performance of video and graphics operations, resource scheduling and security. The improved security offered by the single chip computer system enables program code or data stored external to the single chip computer system to be encrypted so as to hinder unauthorized access, while internal to the single chip computer system the program code or data is decrypted. The single chip computer system is particularly suitable for video game consoles having high quality graphics and/or video, digital video disk (DVD) players, and set-top boxes.
