When a CPU is processing a first task by using an accelerator for use in image processing, if a request for allocating the accelerator to a process of a second task is issued, the CPU sets an interruption flag when the process of the second task is prioritized over a process of the first task, and the accelerator is allowed to be used for the process of the second task when a state in which the interruption flag is set is detected at a timing predetermined in accordance with a process stage of the accelerator for the first task. Since the timing of detecting the set interruption flag is determined in accordance with a progress state of the process of the task to be interrupted, task switching can be made at a timing of reducing overhead for save and return for the process of the task to be interrupted.

A consumption value of each storage medium and an upper limit related to writing are managed. Respective consumption value and the upper limit of each of two or more storage media out of a plurality of storage media constituting a storage media group are specified, and a remaining use period value is computed for each of the storage media using the upper limit and the consumption value. Based on each of the computed remaining use period values, data in at least one storage medium out of a plurality of storage media belonging to the selected storage area group is shifted to a storage medium which is different form the storage area group.

The first circuit has a function of retaining data in a first period during which a power supply voltage is supplied. The second circuit has functions of saving the data retained in the first circuit in the first period and retaining the data saved from the first circuit in a second period during which application of the power supply voltage is stopped. The third circuit has functions of saving the data retained in the second circuit in the second period and retaining the data saved from the second circuit in a third period during which application of the power supply voltage is stopped. The second circuit is capable of being written with the data for a shorter time than the third circuit. The third circuit is capable of maintaining the data for a longer time than the second circuit.

It is intended to provide a memory control device and memory control method capable of reducing charge/discharge current consumed while various commands are inputted to a semiconductor memory device and reducing occurrence of power noises. During periods TT1, TT2, and TT3 which are parts of a period tCKE in which a clock enable signal CKE is in active state, supply of a control clock SD_CLK from a memory control device 1 to a synchronous-type semiconductor memory device 12 can be stopped. Furthermore, in case an input of a data input/output period of an external command and that of refresh operation period of a refresh command RCMD overlap and an access region of the external command and that of the refresh command RCMD do not coincide, those commands are converted to control command signal SD_CMD in parallel, whereby parallel conversion processing operation can be conducted.

There is provided a digital camera to which external programs can be installed for appending desired functions thereto. Print image data generating programs to be stored in a recording medium in the digital camera are transmitted from a personal computer, an external extended recording medium of the digital camera, or an external device via a modem and a communication line. In any cases, the stored programs are read out at desired time to execute an print image data generating processing which transmits the print image data to a printer for printing the image. The stored program can be deleted at a desired time.

A distributed processor architecture computer system and method that includes one or more processors and object oriented control program for real time and near-real time streaming data processing which is able to change the underlying communication mechanism at runtime, which includes the use of a software interface that hides the underlying communication mechanism. The present invention permits the accommodation of changes in communication resource availability due to link, equipment, or software failures or communication bandwidth resources being used by other collaborating programs. The ability to select a communication mechanism based upon cost performance for the particular program deployment and communication mechanism availability as described in the present invention. Typical criteria used for selecting different communication mechanisms for streaming a high volume data on each individual connection would include lower latency, lower overhead time per message, higher throughput in bytes per second of a particular computer, communication equipment and operating system independence.

Erasing is performed with respect to a nonvolatile memory cell without causing depletion halfway therethrough. A control circuit for reversibly and variably controlling the threshold voltage of the nonvolatile memory cell by electrical erasing and writing controls an erase process of performing erasing to the plurality of nonvolatile memory cells assigned to one unit in an erase operation, a first write process of performing writing to the nonvolatile memory cell exceeding a pre-write-back level before a depletion level, and a second write process of performing writing to the nonvolatile memory cell exceeding a write-back level after the first write process. Since the occurrence of depletion is suppressed by successively performing the first write process with respect to the nonvolatile memory cells which may exceed the depletion level in the erase process, erasing can be performed to the nonvolatile memory cell without causing depletion halfway therethrough.

The invention discloses a high refresh rate waveform mapping method and a digital oscilloscope. The method comprises the following steps: continuously obtaining multiple frames of collected data of signals (S100); arranging each data point of each frame of collected data in a corresponding display array, and forming a coordinate code of the data point by utilizing the code value of each data pointand the serial number of the display array where the data point stays (S200); counting the times that each data point appears at corresponding coordinate code to obtain the statistical result of thearray column diagram, and counts the maximal code value and minimal code value in each display array so as to obtain an array peak value statistical result (S300); according to the statistical result,carrying out waveform mapping on the signals, and refreshing the display brightness of each pixel in the waveform mapped region (S400). According to the waveform mapping method, a statistical value mapping mechanism is used to replace a conventional each frame individual mapping mechanism, the situation that data acquisition of each frame needs individual mapping is avoided, the time for waveformmapping is reduced, and the refresh rate is improved.
