  • Patent number: 6749514
    Abstract: There is provided a game system and information storage medium in which a player can easily grasp the contents of the saved data or the game state on the data saving. The game system can play a game based on a desired saved data when the desired saved data is selected and loaded from items of saved data. The game system has a saved-contents reminder image generating section (144) for generating a saved-contents reminder image containing at least one of scene and character which remind a player of the contents of the saved data or the game state on the data saving, and a load information selecting section (114) which outputs the saved-contents reminder image when a player selects saved data to be loaded. The contents of a frame buffer on the data saving may be used as a saved-contents reminder image.

  • Publication number: 20040054874
    Abstract: A data processing device capable of high speed operation and shorter instruction processing time without causing software compatibility problems. When storing an instruction from the memory into the instruction cache memory and the instruction possesses a spare field, the instruction code of that instruction is predecoded in the predecode-processor and the information generated is stored in the spare field corresponding area of the instruction cache memory. When that instruction is fetched from the instruction cache memory, the information stored in the spare field corresponding area of the instruction cache memory is utilized. In this way, processing can proceed based on the predecoded information without having to await the completion of decoding of the instruction fetched from the instruction cache memory.

  • Publication number: 20020101257
    Abstract: A semiconductor device having a functional circuit block with predictive power controller is provided so as to construct a system LSI manufactured in the practicable number of design steps, which is extensible and in which power is reduced. The functional circuit block includes a prediction circuit and a predictive power shutdown circuit having a power status control circuit. The prediction circuit controls a power status of the functional circuit block by using the power status control circuit, based on input information thereto. When no information is inputted for a predetermined a period of time, the power status control circuit shifts to a power status of the functional circuit block to a low-power status.

  • Publication number: 20020026570
    Abstract: In view of a necessity of alleviating factors obstructing an effect of SIMD operation such as in-register data alignment in high speed formation of an SIMD processor, numerous data can be supplied to a data alignment operation pipe 211 by dividing a register file into four banks and enabling to designate a plurality of registers by a single piece of operand to thereby enable to make access to four registers simultaneously and data alignment operation can be carried out at high speed. Further, by defining new data pack instruction, data unpack instruction and data permutation instruction, data supplied in a large number can be aligned efficiently. Further, by the above-described characteristic, definition of multiply accumulate operation instruction maximizing parallelism of SIMD can be carried out.

  • Patent number: 5398009
    Abstract: In order to improve filter loss of a waveguide filter having coaxial/waveguide mode conversion parts at its ends, conductor posts bridging a space between two long sides of the waveguide are provided between the parts and the ends. The conductor posts have sufficient thickness and remain close enough to each other and to short ends of the waveguide that a partition plane including axes of the conductor posts can be regarded as an imaginary short plane. The conductor posts are located so that the partition plane is positioned at a distance .lambda./4.times.n (n=1, 3, 5 . . . ) from the coaxial/waveguide mode conversion part.

  • Patent number: 4471192
    Abstract: A microwave heating apparatus of a dielectric heating system used in combination with a radiant heat source.A leakage waveguide group is formed by arranging a number of leakage waveguides, each having at least in one side surface thereof an electric wave radiation opening which may be in the form of a long slit; and the same is closed at each electric wave radiation opening thereof with heat resistant non-metal material such as Teflon, glass or the like and is arranged so that a heating medium such as hot air, steam or the like may be passed therethrough.According to this construction, as compared with a conventional microwave heating apparatus of this kind, the heating energy is more sufficiently consumed in an object to be heated, so that the heating speed can be improved and the available space in the heating chamber can be enlarged.
