A device for biological material detection includes a substrate; a through-hole through which a biological material to be tested passes, the through-hole being formed in the substrate; a molecule that interacts with the biological material to be tested passing through, the molecule being formed in the through-hole; a first chamber member that forms, with at least the surface including the through-hole on one surface side of the substrate, a first chamber to be filled with electrolyte; and a second chamber member that forms, with at least the surface including the through-hole on the other surface side of the substrate, a second chamber to be filled with electrolyte. The biological material to be tested is identified by the waveform of the ion current (passage time, shape, etc.) when the biological material to be tested passes through the through-hole.

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 flows 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 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.

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.

Method of producing image data and associated recording medium

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.

A structure of the three-dimensional image data, excluding the information to be perspective view transformed, is arranged identical to that of the given transmission standard of the two-dimensional image data. Accordingly, in the GTE, the information to be perspective view transformed is discriminated from the other data of the three-dimensional image data wherein the structure is identical to that of the given transmission standard of the two-dimensional image data, subjected to the perspective view transformation, and is combined with the other data wherein the structure is identical to that of the given transmission standard for production of the two-dimensional image data. An original format file including data to be transformed is thereby easily converted into a file having a new format.
