  • Patent number: 6651082
    Abstract: A system and method which dynamically changes the load balance of assigned loads for each group in a sequence of processes from a first stage to an n-th stage in a computer having a plurality of processors, wherein the plurality of processors are grouped into at least two groups, comprises the steps of: detecting a change in a characteristic value in a queue for transferring a processing result between the groups; and changing the assignment of assigned processes for each group based on the change in the characteristic value. A characteristic value stored in a queue represents a value related to work load, and a queue seldom becomes full or empty if the load balance is changed referring to this characteristic value.

  • Patent number: 6559855
    Abstract: The present invention enables image information of high resolution to be transferred via a transmission line with limited band width using a simple configuration. In transferring image information between a main body of a computer and a display, a dither matrix is used to update images stored in the display. That is, a plurality of blocks whose size is of a predetermined dither matrix are defined in an image, and information of each pixel in each block is transferred to the display in order of a value of a corresponding element in the dither matrix. Transfer of unchanged pixel data can be omitted. In addition, in transferring image information between the main body of the computer and the display, image information stored in the computer is divided into a plurality of blocks, for each of which the number of changed pixels or the number of writings to pixels in the block is calculated so that image information in blocks which exceed a predetermined number is transferred to the display block by block.

  • Patent number: 5757374
    Abstract: A computer graphics apparatus connects a texture coordinate generator with fragment generators via a command bus. The generator is connected to a texture data bus through a texture memory cluster which comprises an address generator connected to a texture coordinate bus, a filter, and eight memories. In addition, the generator is connected to the texture data bus through a plurality of texture memory clusters. The texture data bus is connected to a plurality of drawing processors to which a plurality of frame memories are connected in correspondence. This configuration performs texture mapping through effective utilization of the texture memory clusters.
