  • Patent number: 7165151
    Abstract: To enhance the speed of first access (read access different in word line from the previous access) to a multi-bank memory, multi-bank memory macro structures are used. Data are held in a sense amplifier for every memory bank. When access is hit to the held data, data latched by the sense amplifier are output to thereby enhance the speed of first access to the memory macro structures. Namely, each memory bank is made to function as a sense amplifier cache. To enhance the hit ratio of such a sense amplifier cache more greatly, an access controller self-prefetches the next address (an address to which a predetermined offset has been added) after access to a memory macro structure so that data in the self-prefetched address are preread by a sense amplifier in another memory bank.

  • Publication number: 20060202992
    Abstract: In a data processor and a shading apparatus used in the data processor, the data processor selects an address based on the information of a memory or a translation look-aside buffer. Therefore, even when the same data are accessed, a different address at high speed is adopted according to the hardware, object to be processed, processing, etc. A plurality of geometric vectors are given as the parameters for the vertexes of a picture, the vectors are interpolated in the picture, and the luminance of each small area in the figure is calculated using the vectors generated by the interpolation. Therefore, a spotlight or highlight can be expressed with high accuracy and at high speed even when the amount of the hardware and the extent of the picture are small.

  • Publication number: 20060052544
    Abstract: Disclosed is a method for producing a propylene-based resin composition comprising: a first step of producing a first resin composition (MB) by melt-kneading a first-propylene polymer (A-I) and a fibrous inorganic filler (B) in a weight ratio of (A-I) to (B) of from 3/7 to 7/3; and a second step of producing a second resin composition by adding a second propylene polymer (A-II), a non-fibrous inorganic filler (C) and an elastomer (D) selected from the group consisting of olefin-based elastomer and vinyl aromatic compound-containing elastomer to the first resin composition (MB), followed by melt-kneading them.

  • Patent number: 6911497
    Abstract: A polypropylene resin composition having a melt flow rate of 70 to 120 g/10 min (at 230° C., 2.16 kgf-load), a flexural modulus of 1300 to 4000 MPa and an IZOD impact strength of 30 to 100 kJ/m2, wherein the composition is obtained by adding a small amount of an organic peroxide to a mixture comprising 60 to 80% by weight of a specific propylene-ethylene block copolymer made up of a propylene homopolymer portion and a propylene-ethylene random copolymer portion, a rubber which is a copolymer of ethylene and at least one ?-olefin having a melt flow rate of 2 to 10 g/10 min (at 190° C., 2.16 kgf-load), and inorganic filler (C), and kneading the combined ingredients at a temperature of 170 to 280° C.
