摘要:
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.

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.

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.

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 frame storage stores an image obtained by imaging a region of at least part of the body of a user. A vital sign signal detector detects a signal sequence of a vital sign that cyclically varies from plural imaged regions of the body of the user by using captured images of a predetermined number of frames stored in the frame storage. A correlation calculator obtains the correlation between the signal sequences of the vital sign detected from the respective imaged regions of the body. An identity determining section determines whether or not the respective imaged regions of the body belong to the same user based on the correlation between the signal sequences of the vital sign detected from the respective imaged regions of the body.

An entertainment device includes a general-purpose signal processor made up of an assembly of component-processors, each of which can operate in parallel under operating environments independent of others component-processors. A management processor controls a cross bar so as to change the operating environments of the respective component-processors in accordance with a demand for signal processing which is given from a CPU, and to change over any one of the component-processors which receives a signal to be processed which is inputted through the cross bar or outputs a processed signal in accordance with the demand for signal processing.
