  • Patent number: 9032417
    Abstract: A information processing apparatus having a processor is controlled to execute a procedure of reading from the memory attribute information indicating a usage frequency of a register used by a process to be executed as a next process by the processor when the processor switches a process currently being executed, saving a value of the register used by the next process to be executed by the processor to the memory when the usage frequency of the register indicated by the attribute information is larger than a certain frequency, reading from the memory owner information indicating a process using the register to be used by the next process when the usage frequency of the register indicated by the attribute information is larger than the certain frequency, and restoring a register value saved in the memory to the register when the owner information indicates a process other than the next process.
    Type: Grant

  • Patent number: 8065569
    Abstract: An information processing apparatus includes a plurality of hardware resources and operates on a first power supply. The apparatus includes a non-volatile first storage unit that holds first fault information on a fault developed in one or more of the hardware resources even when the first power supply is shut down, a volatile second storage unit that holds second fault information different from the first fault information and is adapted not to hold the second fault information when the first power supply is shut down, a hardware monitoring unit that acquires component information of the plurality of the hardware resources mounted in the information processing apparatus and a system control unit that makes a fault information management unit restore the second fault information held in the second storage unit based on the component information and the first fault information stored in the first storage unit.

  • Patent number: 4989981
    Abstract: In order to accurately scan an object for the purposes of determining the dimensions, surface finish or the like, the position of the object according to the measuring system coordinate grid is determined. Using this orientation, the degree of misalignment with respect to a standard position on the grid is determined and the scanning devices which perform the actual measurement, are moved to positions which take the amount of misalignment into consideration and wherein accurate examination is assured.
