    摘要: Provided is information processing apparatus, information processing method and a record medium, which can prevent occurrence of manipulation, in a case of accessing a memory, without consuming the access band of the memory. A main-processing unit, a sub-processing unit and a memory for loading a program are provided and process limit information stored in the memory is stored in storing means. The sub-processing unit judges whether a program to be executed is manipulated or not, and loads a program to be executed in the memory in case that the program is not manipulated. The sub-processing unit refers to the process limit information before execution of a program, and not permits execution of the program of the main-processing unit in case that a process by the main-processing unit for information stored in the memory accords with a process included in the process limit information.

    摘要: An I/O device performs data input and data output between the I/O device and first and second computers. An I/O switch relays input and output data between the I/O device and each of the first and second computers. A device emulator emulates the I/O device when a virtual machine running on the first computer and directly accessing the I/O device is migrated from the first computer to the second computer. A connection controller controls switching connection between any one of the first and second computers and any one of the I/O device and the device emulator. The first computer is connected to the I/O device and the second computer is connected to the device emulator until the virtual machine running on the first computer is stopped, and the second computer is connected to the I/O device after the virtual machine running on the first computer is stopped.

    摘要: An IC chip, a board, information processing equipment, and a storage medium are provided that can prevent, even when information is transferred between a plurality of programs, leaking of the right protection algorithm of information in connection with the transfer. A security board is included an IC chip having a secure module. The secure module receives an encryption key request signal, and generates a communication encryption key every time when the encryption key request signal is received, the communication encryption key being used to encrypt information to be transferred between a plurality of programs. The number of times the communication encryption key is supplied is counted. If the counted number is equal to or less than a predetermined number, the communication encryption key is supplied to outside. If the counted number exceeds the predetermined number, the supply of the generated communication encryption key to outside is stopped.

    摘要: In the synchronous motor controlling apparatus and method of the invention, a current is detected and subjected to coordinate transformation onto &ggr;-&dgr; axis assumed for the rotor. A correction term is obtained on the basis of the derived current and an arbitrarily given correction current instruction. A &ggr;-&dgr; axis voltage instruction is computed by adding a value obtained by multiplying the correction term by a proper gain to a voltage equation in a steady state of the synchronous motor. Consequently, a control method of small computational load, which does not require gain adjustment according to the inertia of a motor load, can be attained.

    摘要: A mobile terminal includes a display device and a processor. The processor acquires first display information about a first virtual machine. The first display information does not prompt a user operation. The processor displays the acquired first display information in a first display area on the display device. The processor acquires second display information about the first virtual machine. The second display information prompts a user operation. The processor displays the acquired second display information in a second display area on the display device. The processor determines, in response to an instruction for changing display, whether mixed display is allowed by referencing status information. The processor acquires, when the mixed display is allowed, third display information about a second virtual machine. The third display information does not prompt a user operation. The processor displays the acquired third display information in a third display area on the display device.
