  • Patent number: 6677955
    Abstract: The present invention is characterized by first performing the necessary rendering in the frame period, then during the remaining time of that frame period, rewriting the texture data in the texture buffer memory. The image rendering process for each frame is performed first, then after the rendering process has been completed for the frame, if there is remaining time, that time is used to rewrite the texture data. Therefore, the rendering process is not interrupted, the displayed image is not interrupted or frozen, and it is possible to rewrite the texture data in the small-capacity texture buffer memory and make it possible to use virtually a lot of texture data to render one scene.

  • Patent number: 6561909
    Abstract: When an event is generated in a game progressing in a first game device, the first game device sends a call signal to a second game device through network. When the second game device receives the call signal, an event is generated in the game progressing in the second game device. In this way, an event is accidentally generated independently from the progress of the game when the game device receives a telephone call signal, in addition to a spontaneous event which is generated according to the progress of the game. Therefore, the user of the game can experience enjoyment which an ordinary game cannot provide, or a thrill which no one can predict will happen. After transmitting/receiving the call signal, the telephone call is cut-off before the game devices enter communication status, so a communication cost is not charged. Since the cost for communication is free, the user can enjoy a communication game at low cost.

  • Patent number: 6527640
    Abstract: When a trigger signal is outputted from a simulated gun 30A to 30D, a trigger image is displayed on image monitor means 20 in response to the trigger signal. In response to a timing signal of the simulated gun 30A to 30D, an indicated position, a value of an image display counter 12 at the time is set in a register 13. Coordinate values of the indicated position of the simulated gun 30A to 30D set in the register 13 is inputted to a game control unit 14 in a horizontal flyback time of a scanning line. The indicated position detection processing for detecting indicated positions indicated on the image monitor means 20 by the simulated guns 30A to 30D is performed at every horizontal scan displaying the video screen.

  • Patent number: 6523082
    Abstract: In a system having a plurality of CPUs connected to a plurality of corresponding bus bridges which are connected in tandem, one of the plurality of bus bridges is associated with a memory storing boot programs for activating the plurality of CPUs. The CPU connected to the bus bridge associated with the memory gains access to the memory by accessing a predetermined address of the bus bridge. The remaining CPUs gain accesses to the same address as the predetermined address, of the bus bridges to which are connected respective CPUs. The thus accessed bus bridges have accesses to the memory by accessing the same address as the predetermined address, of the other bus bridges adjacent toward the bus bridge associated with the memory.

  • Patent number: 6522337
    Abstract: An image processing apparatus of the present invention conducts update processing of MIPMAP-format texture data within an updateable range, and during drawing processing, it ascertains the level of detail to which texture data has been updated. Thereupon, when conducting texture mapping, texture data of the level of detail for which updating has been completed is used. In this case, if the required texture data has not been updated, then it is substituted by texture data for which updating has been completed. Consequently, even in cases where updating of all texture data is not completed in time, it is possible to prevent significant distortion of the image due to mixing of updated and non-updated texture.
