摘要:
The present invention relates to the architecture and use of a computer system optimized for the efficient modeling of graphics. The computer system has a primary processor and a graphics processor. The primary processor has two vector processor units within it, one which is closely connected to central processor unit. Simultaneously performing complex modeling calculations on the first vector processor and CPU, and geometry transformation calculations on the second vector processor, allows for efficient modeling of graphics. Furthermore, the graphics processor is optimized to rapidly switch between data flow from the two vector processors. In addition, the graphics processor is able to render many pixels simultaneously, and has a local memory on the graphics processor chip that acts as a frame buffer, texture buffer, and z buffer. This allows a high fill rate to the frame buffer.

The present invention relates to the architecture and use of a computer processor optimized for instruction and data processing. The computer processor includes a main processor element in operative communication with a main memory for storing data, and sub-processor elements in operative communication with the main processor element for processing the data. Each of the sub-processor elements including a dedicated local memory for storing instructions and data. The main processor desirably comprises a primary processor core, and the sub-processor elements desirably include a set of coprocessors. One of the coprocessors may be an embedded coprocessor that performs error checking in the primary processor core. Another one of the coprocessors may be a vector processing unit. A program can directly control the vector processing unit or may indirectly control it via the primary processor core.

An image processing system for producing an image from three-dimensional image data. The system uses a command generator to generate one or more plotting commands for producing the image, and features a coordinate calculator for transforming the three-dimensional data into two-dimensional data. The coordinate calculator operates as a coprocessor of the command generator, and as such does not require use of the system bus to perform its functions.

Methods and apparatus for generating image data are provided. A memory and a data processor are coupled with a system bus. In certain embodiments a data expanding apparatus is also coupled to the system bus and compressed data are transferred to the data expanding apparatus via the system bus and decompressed data are transferred therefrom to the memory without passing the compressed data through the data processor. Also in certain embodiments, an image data generation command string is transferred from the memory to an image data generation device via the system bus without passing the image data generation command string through the data processor.

An entertainment apparatus is configured to enable a program for an older version of the apparatus to be executed. In a normal mode, a main processing unit (MPU) operates as a main CPU, a graphics processor (GP) operates as a graphics processor, and an input/output subprocessor (IOP) operates as a subprocessor for input and output. In a compatible mode in which a program for an older version of the apparatus is executed, the IOP capable of executing the program for the older version of the apparatus operates as a main CPU, and the MPU and GP emulate a graphics processor for the older version of the apparatus.

Objects which are created in conformity with the data format of objects to be handled in a virtual world are offered to users on the terminal computers of the users independently of the virtual world. The users transmit the offered objects to a server computer which generates the virtual world, while the server computer stores these objects in association with the operators. Since these objects are recorded in a format which can be interpreted by the server computer for generating the virtual world, they can be handled in the virtual world in the same manner as the other objects which have been defined in the virtual world beforehand. Thus, the users are permitted to use in the virtual world objects which are different from the objects which were defined in the virtual world beforehand.

A data format is provided capable of assigning a desired color lookup table (CLUT) to a texture pattern of each polygon drawn on a two-dimensional display screen. Assuming that TPF represents a pixel depth of the texture pattern, when TPF is 00, 01, and 10, the format (CLUT) is applied of a 4-bit mode, an 8-bit mode, and 16-bit mode respectively, whereby its related command is decreased in word length and thus requires less storage in a source video memory.

A method and apparatus for generating images wherein access to a main memory is minimized during a translation of an image of a 3D object or the like on a display screen to increase the speed of the translation process. A string of draw commands for drawing an image is preceded by an offset draw command which indicates offset values for the coordinates of the vertices of the image, and the image is translated on the display screen in accordance with the offset draw command. A header portion of each of the offset draw command and the draw commands that constitute the draw command string includes data indicating the address on the main memory of the next draw command to be executed. The image generation apparatus includes a frame buffer in which an image is drawn, a CPU for generating a string of draw commands to draw the image and an offset draw command indicating offset values for the coordinates of the vertices of the image, a main memory for storing the string of draw commands and offset draw command generated by the CPU, and a drawing device portion for executing the string of draw commands and offset draw command from the main memory to draw a translated image on the frame buffer.
