  • Information processing apparatus and method for processing three-dimensional graphics using a second information processing unit for processing processed-related information
    Patent number: 6388671
    Abstract: An information processing apparatus includes a dedicated graphic hardware part dedicated to execution of a specific process function under a pipeline process scheme, and a microprogram execution part executing a process using a microprogram. When three-dimensional graphic information is processed, a process for determining endpoints is executed by the microprogram execution part, and an interpolation process started from an endpoint is executed by the dedicated graphic hardware part for each endpoint process. While the dedicated graphic hardware part is executing the interpolation process, the microprogram execution part is operated in parallel so as to execute the endpoint process for a next endpoint.
