According to an aspect of embodiments, there is provided a random number generating circuit including at least one magnetic tunnel junction (MTJ) element and a control circuit. The MTJ element comes into a high resistance state corresponding to a first logical value and also comes into a low resistance state corresponding to a second logical value different from the first logical value. The control circuit supplies the MTJ element with a first current for stochastically reversing the MTJ element from the high resistance state to the low resistance state when the MTJ element is in the high resistance state, and supplies the MTJ element with a second current for stochastically reversing the MTJ element from the low resistance state to the high resistance state when the MTJ element is in the low resistance state.

According to a data display method, data having a program unit and instruction data for the program unit multiplexed on bit stream data is received. The program unit is extracted from the received data and is stored in a memory. The instruction data is extracted from the received data, and the program unit or part thereof specified by the instruction data is read from the memory and is executed. Then, the bit stream data and the execution result are displayed. This ensures smooth synchronization of reproduction of a bit stream with execution of an associated program and efficient use of resources.

A file memory stores data corresponding to identifiers of an allocated area in an identifier space. A first memory stores a basis position of the allocated area in the identifier space. A second memory stores a weight of the storage apparatus as a performance degree. A first decision unit decides a space width to divisionally allocate the identifier space with another storage apparatus by using the weight and a weight of another storage apparatus. Another storage apparatus allocates a neighboring area of the allocated area in the identifier space. A second decision unit decides the allocated area of an area between the basis position and a basis position of the neighboring area in the identifier space by using the space width.
摘要:
A parity adder obtains a second data by adding a parity for first data to be written to a memory to the first data. An access-key register holds an access key unique to a source of request. A first operating unit obtains a third data by calculating an XOR between the second data and the access key, the access key being set by the source of request for writing data to the memory. A second operating unit obtains a fourth data by calculating an XOR between the access key and the third data. A syndrome calculator calculates a syndrome from the third data, the access key being set by the source of request for reading data from the memory. A determining unit determines whether to output the third data as the first data, based on calculated syndrome.

A scheme for managing nodes connected to a home network according to their physical location is disclosed. A communication device constituting each node is formed by at least one communication unit for carrying out communications through a connected network, having communication ports for connecting nodes through which data are to be exchanged by the nodes, and a configuration information memory unit for storing a configuration information regarding a configuration of the communication device, having a region for dynamically describing a location information regarding a physical location of the communication device. At a managing node, a configuration information of a connected network and a location information regarding a physical location of a prescribed node connected to the network are collected, and physical locations of other nodes/services that are connected to the prescribed node are managed by regarding the other nodes/services as existing at an identical physical location as the physical location of the prescribed node as specified by the location information.
摘要:
A computer system includes a plurality of clusters each having at least one resource. At least one cluster has a resource matched with static resource information of a cluster discovery request. The at least one cluster is selected by referring to static resource information of resources in each cluster of a discovery object. The at least one cluster is a candidate cluster. A resource matched with dynamic resource information of a resource discovery request is searched from the candidate cluster by referring to dynamic resource information of resources in the candidate cluster.

In the disclosed data transfer request processing scheme, data transfer requests with deadlines for completing requested data transfers are classified into first class data transfer requests and second class data transfer requests. Then, the processing of first class data transfer requests is scheduled according to a first scheduling policy in which a completion of data transfers requested by the data transfer requests within the deadlines specified for the data transfer requests is a primary key factor in determining an order of processing, while the processing of second class data transfer requests is scheduled according to a second scheduling policy in which a reduction of amounts of the mechanical actions required in carrying out data transfers requested by the data transfer requests is a primary key factor in determining an order of processing. Then, the data transfer requests are processed according to a scheduling result so as to control the storage device to carry out data transfers requested by the data transfer requests. In this way, it is possible to schedule the processing order of the data transfer requests such that the amount of mechanical actions can be reduced, by taking the durability of the mechanical parts in consideration.
