Abstract: An output FIFO data transfer control device can comprise a geometric arithmetic core including one integer processing unit or IPU and a plurality of floating-point processing units or FPUs. Each processing unit includes an intermediate buffer or data output buffer for storing a data on an arithmetic result. When an instruction of data transfer from at least one of the plurality of processing units to one output FIFO is issued, a write/read pointer generating unit generates a write pointer identifying a specific location where data on an arithmetic result associated with the instruction is to be stored in the intermediate buffer of at least one of the plurality of processing units. The write/read pointer generating unit also generates a read pointer identifying a specific location where data is to be read out of the intermediate buffer of at least one of the plurality of processing units.

Abstract: An X-ray CT apparatus includes a scanner mounted with a detection system having an X-ray source for generating X-rays applied radially to an object and a detector arranged so as to be opposite to the X-ray source and adapted to detect the image of the transmitted X-rays transmitted through the object, wherein the scanner is rotated around the object. A three-dimensional X-ray absorption coefficient distribution image of the object is reconstructed from the transmitted X-ray image and the rotation-axis projection position which is the position where the rotation center of the scanner is projected on the detection plane of a two-dimensional sensor constituting the detector is decided. On the basis of the contrast of the X-ray absorption coefficient distribution image reconstructed by using the decided rotation-axis projection position, the rotation-axis projection position is estimated, and an X-ray tomographic image or/and a three dimensional X-ray image of the object is generated.

Abstract: It is judged that a vertex exists within a view volume when values stored in registers (231 to 236) are all "1". In other words, whether the vertex exists within or beyond the view volume can be judged by whether the values stored in the registers (231 to 236) are all "1" or not. To meet this requirement, a clip code generation/judgment unit (20) comprises a 6-input AND gate (24) which obtains a logical product of the values stored in the registers (231 to 236) to output a judgment signal (M1). With this configuration, a first step for clipping, i.e., the judgment on whether a primitive exists within or beyond a view volume is implemented in hardware, and thereby the operating speed is improved.
