An apparatus for performing data processing for a print job, includes a controller to control data processing in accordance with a number-of-copies setting of a print job. The data processing includes first data processing in which predetermined image processing is performed on first image data included in the print job to generate second image data, and the generated second image data is printed without spooling; and second data processing in which predetermined image processing is performed on first image data included in the print job to generate second image data, the generated second image data is spooled, and the spooled second image data is repeatedly used for printing. When a change of the number-of-copies setting is accepted during job execution by the first data processing, the controller switches from the first data processing to the second data processing in response to the remaining number of copies.

A printing apparatus conveys a printing medium in a first direction, and includes an encoder that outputs a predetermined signal in accordance with a conveyance amount of the printing medium in the first direction, and a print head having a plurality of nozzle rows, each of which includes a plurality of nozzles ejecting ink, arrayed in a second direction intersecting with the first direction. In addition, a print engine is connected with the print head and performs conversion processing from image data into print data. The print engine has a first buffer storing the image data, has a second buffer storing the print data, and converts image data stored in the first buffer into print data in response to a first interrupt signal based on the predetermined signal output from the encoder, and stores the print data in the second buffer.

A memory control method receives a read request data set including a management ID and requesting reading of data from a memory, transmits read data that is read corresponding to the read request, stores write data temporarily in a write buffer, stores the read data read from the memory temporarily in a read buffer, stores write control data and read control data in an arbitration queue, executes an arbitration that determines a priority order of processing taking the write control data and the read control data that are stored in the arbitration queue as targets, and matches an order of transmitting a plurality of pieces of read data that are read from the memory corresponding to the read control data selected based on the determined priority order and are associated with an identical management ID to an order of receiving the read request data set.

A memory control method generates write control data by predetermined areas by attaching processing priority data and a transfer ID, generates read control data for respective predetermined areas by attaching processing priority data and a transfer ID, stores the write control data and the read control data in an arbitration queue, executes an arbitration that determines a priority order of processing taking the write control data and the read control data that are stored in the arbitration queue as targets, and changes the processing priority data every time a predetermined time elapses. The arbitration raises a priority order taking the write control data or the read control data that includes the processing priority data as a timeout request when the processing priority data has passed a preliminarily set threshold by the change.

An information processing apparatus collects data produced in association with processing carried out by the information processing apparatus, and buffers the collected data in a first data format. The first data format is different from a second data format used for transmission to an external server apparatus. The information processing apparatus converts the format of the buffered data from the first data format to the second data format before transmitting the buffered data to the server apparatus. Then, the information processing apparatus transmits the data in the second data format to the server apparatus as an event log of the information processing apparatus.

A memory control method generates processing priority data that represents a priority of processing in controlling a memory, generates write control data including write data and the processing priority data, generates read control data including the processing priority data, stores the write control data and the read control data in an arbitration queue, executes an arbitration that determines a priority order of processing taking the write control data and the read control data that are stored in the arbitration queue as targets, and changes the processing priority data every time a predetermined time elapses. The arbitration raises a priority order taking the write control data or the read control data that includes the processing priority data as a timeout request when the processing priority data has passed a preliminarily set threshold by the change.

A memory control method includes: dividing write data for respective predetermined areas in a memory and attaching transfer IDs to generate write control data for the respective predetermined areas, and dividing read request data set for the respective predetermined areas and attaching transfer IDs to generate read control data for the respective predetermined areas; storing the write control data and the read control data in an arbitration queue; and detecting overlap access request data as a write request data set or a read request data set. The overlap access request data requests an access to an address that is at least partially overlapping an address of received write request data set or read request data set. The arbitration is executed such that the received write request data set or read request data set is processed after the overlap access request data is processed.

A method for transmitting a message between a first electronic device of a first user and a second electronic device of a second user via a timepiece includes: creating the message to be transmitted by the first electronic device; storing the created message on a remote server and/or in the first electronic device as digital message data; generating a digital graphic representation for the transmission of the message by the remote server and/or by the first electronic device; building a figurative representation pertaining to the digital graphic representation for the transmission of the message on all or a portion of the timepiece by a visual element building device controlled by the server; and transmitting the message by the second electronic device from a digital figurative representation emanating from the capture of the figurative representation included on all or a portion of the timepiece, by this second electronic device.

In accordance with an embodiment, an interface device comprises a plurality of interface circuits which respectively corresponds to different transmission paths and sequentially acquires a plurality of packets formed by dividing data which is an object of any one of plural types of information processing via the corresponding transmission paths, a reception buffer and a processor. The processor writes the packet acquired by each of the plurality of the interface circuits in the reception buffer in association with an identification code for identifying the interface circuit acquiring the packet, sequentially reads a plurality of packets associated with the same identification code among the packets stored in the reception buffer from the reception buffer, and delivers the read packets to the information processing on the data which is a basis of the packet.

The present invention is a printing apparatus including: a conveyance unit configured to convey a printing medium; an encoder that outputs a predetermined signal in accordance with a drive amount of the conveyance unit; a print head in which a plurality of nozzle rows in which a plurality of nozzles ejecting ink is arrayed is arrayed side by side in a direction intersecting with a conveyance direction of the printing medium; and a print engine connected with the print head and performing conversion processing from image data into print data, and the print engine: has a first buffer storing the image data; has a second buffer storing the print data; and converts image data stored in the first buffer into print data and stores the print data in the second buffer, in response to a first interrupt signal based on the predetermined signal output from the encoder.
