    摘要: In a multi-processor system including a plurality of processing units each having a cache memory, the processing units each include a synchronization counter for indicating a present synchronization state of the respective processing unit, and a cache state table for holding information regarding the respective entries of the cache memory. The cache state table includes a cache state and a cache synchronization count. The cache state holds the respective cache state used in a cache protocol. The cache synchronization count holds a value of the synchronization counter when an entry is loaded. A cache protocol in the multi-processor system is simplified to realize a high-speed processing.

    摘要: An address translation technique used in a multiprocessor system is disclosed. In a multiprocessor system for connecting a plurality of clusters with each other via a network, each of these clusters is arranged by comprising a plurality of processors; a cluster translator for translating a cluster number; a cluster translation table for storing therein a correspondence relationship between a logical cluster number and a physical cluster number; an address translator for translating an address; and an address translation table for storing therein a correspondence relationship between a logical address and a physical address. The address translation table stores only the data corresponding to a memory employed in the cluster. Accordingly, a total storage capacity of the address translation tables is reduced, and an updating operation of the address translation tables is simplified. Furthermore, the address translation table is exclusively identified based on a local job number and the cluster number, so that operation to update the address translation table is simplified.

    摘要: An optical pick-up apparatus for reproducing information recorded on a magneto-optical record medium including a semiconductor laser emitting a linearly polarized laser beam, and a polarizing film provided between a glass prism and a uniaxial birefringent crystal prism. The laser beam emitted by the semiconductor laser is made incident upon the polarizing film via the glass prism and is reflected thereby. The apparatus further includes an objective lens projecting the laser beam reflected by the polarizing film onto the magneto-optical record medium as a fine spot and converging a return laser beam reflected by the record medium toward the polarizing film. The return beam transmitted through the polarizing film is refracted by the uniaxial birefringent crystal prism and is divided into ordinary light and extraordinary light, which are received by a first photodetector to produce a reproduced information signal. The return beam reflected by the polarizing film is made incident upon a hologram and is diffracted thereby into .+-.1-order beams which are received by a second photodetector to produce a focusing error signal and a tracking error signal.

    摘要: An optical pick-up apparatus for reading and/or writing information from and/or on an optical record medium including a semiconductor laser, an objective lens projecting a laser beam onto the optical record medium, a hologram optical element having a first hologram for diffracting the laser beam onto a first pair of photodetectors to derive a focusing error and a second hologram for diffracting the laser beam onto a second pair of photodetectors to derive a tracking error. Each of the photodetectors of the second pair has light receiving regions which are divided along a division line substantially parallel with a diffracting direction of the second hologram which introduces astigmatism into the diffracted beams. A large tracking error signal can be detected stably on the basis of a distribution of an amount of light in a far field by the push-pull method.

    摘要: A semiconductor device in which low voltage elements and high voltage elements are formed on the same substrate. To simplify the manufacturing process of semiconductor devices and to improve the punch through voltage resistance between elements, when high voltage elements and low voltage elements are formed on the same semiconductor substrate, during the process for injecting p-type impurity into semiconductor substrate in the low voltage sections, at first a mask pattern having openings above the low voltage sections and openings above the element separating areas of the high voltage sections is formed, then p-type impurity is injected into the semiconductor substrate from above the mask pattern, followed by heat-treatment of the semiconductor substrate to diffuse p-type impurity into the semiconductor substrate. Thereby, channel stop diffusion layers comprising p-type impurity layer are formed under the element separating areas formed in the high voltage sections.
