摘要:
A scheme for image selection in an image transmission system for transmitting images from an image source to an image display device, capable of eliminating a need for the viewer to select the desired image by actually watching individual images and easily selecting the desired image in which a specific desired target of the viewer is shown. Feature information for identifying targets shown in each image is obtained, while a desired feature information for identifying a desired target specified by the viewer is entered. Then, the desired image which contains the desired target specified by the viewer is selected according to the obtained feature information and the entered desired feature information. The feature information may be obtained by recognizing targets shown in each image provided by the image source, or may be generated in advance in correspondence to images provided by the image source.

A multiple processor transaction processing system having both a transaction routing unit for routing each transaction generated by the transaction source to one of the transaction processors, and a data arrangement unit for determining data arrangement of the data to be used in processing the transactions by the transaction processors. The transaction routing unit routes each transaction to one of the transaction processors according to the feature parameters extracted from each transaction and the processing history information for past transactions processed by the transaction processors. The data arrangement unit determines a new data arrangement of the data in the data storage regions according to a data storage information indicating original arrangement of the data in the data storage regions and the correlation information indicating all sets of data which are accessed together in each series processing carried out by the transaction processors.

A flexible distributed processing system capable of dealing with sophisticated conditions for selecting a server process. In the system, each of the services provided by all server processes is registered in the service manager in correspondence with an executability condition for judging whether each service is executed, such that the service manager selects one of the server processes which is providing the desired service indicated by the inquiry transmitted from the client process and which is judged to be executable according to the executability condition registered at the service manager, and the client process requests the desired service the selected one of the server processes. The system can utilize a transaction processing for a nested transaction in which a commit processing for the processes of the sub-transactions which are incapable of executing the nested transaction, is completed concurrently with a completion of the commit processing for the top level transaction.

A cache memory has a data holding unit having multiple cache lines each of which includes an address area, a data area and a dirty bit, and a controller which is given read data and a correction execution signal indicating whether or not error correction has been performed for the read data, the read data has been read from a memory storing error-correction-coded data, which also stores address information corresponding to the read data into the address area of any one of the multiple cache lines, stores the read data into the data area, and sets a predetermine value as the dirty bit on the basis of the correction execution signal.

A information processing apparatus includes, upon instructing for writing back stored contents of a main memory unit to the stored contents of the main memory unit at the time of previous modification in a sequence number that is used for identifying whether write back to the main memory unit is needed, from a backup data stored in a backup memory unit, the sequence number stored in a sequence number memory unit. The information processing apparatus selects the backup data including an integrity verification data indicating that writing is carried out completely. The information processing apparatus extracts an original data and a write destination address included in the selected backup data and writes the original data, for each original data and the write address extracted from the backup data, to a storage area, of the main memory unit, indicated by the write destination address.

An information processing system performs a plurality of tasks within a specific time interval. The system includes a bus, a plurality of processors which transfer data via the bus, and a unit for performing a scheduling operation of determining execution start timing of each of the tasks and at least one the processors which executes the tasks, based on cost information concerning a time required to perform each of the tasks and bandwidth information concerning a data transfer bandwidth required by each of the tasks, to perform the tasks within the specific time interval without overlapping execution terms of at least two tasks of the tasks, the two tasks requiring data transfer bandwidths not less than those of the others of the tasks.

摘要:
An information processing system performs a real-time operation periodically at specific time intervals. The system includes a unit for performing a scheduling operation of assigning the real-time operation to a processor to perform the real-time operation periodically at the specific time intervals by the processor, a unit for computing a ratio of an execution time of the real-time operation to be performed by the processor at a first operating speed, based on the specific time intervals and cost information concerning a time required to perform the real-time operation by the processor at the first operating speed, and a unit for performing an operating speed control operation to operate the processor at a second operating speed that is lower than the first operating speed, the second operating speed being determined based on the computed ratio.
