Abstract: 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.

Abstract: 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.

Abstract: Provided is an image processing apparatus for increasing the speed of pixel processing of index colors. A LUT reading unit reads a LUT for converting index colors to pixel values for each plane. A first storage unit stores the look up table read by the LUT reading unit. A plane LUT copying unit acquires pixel values corresponding to each place from the look up table stored in the first storage unit. A second storage unit stores the pixel values acquired by the plane LUT copying unit. A pixel processing unit performs image data processing using the pixel values stored in the second storage unit.

Abstract: A memory control method uses a memory including a plurality of bank groups each having a plurality of banks. The memory control method includes masking write control data and read control data based on an inside-bank group constraint period that is a command to command interval during which a processing is restricted inside an identical bank group and an inter-bank group constraint period that is a command to command interval during which a processing is restricted inside different bank groups, and storing an unmasked command in an arbitration queue. An arbitration raises a priority order of control data requesting a processing on the bank group that has been accessed last among the plurality of bank groups.

Abstract: 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.

Abstract: 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.

Abstract: A system and method for implementing a real-time state machine with a microcontroller is disclosed. The method includes using a two-stage process, including a configuration stage and a run-time stage, for processing objects for a printing device. The configuration stage is executed prior to the run-time stage, which operates in real-time. During the configuration stage, the system predetermines a state transition list, devices that need to be monitored, devices that need to be controlled, and other variables used during the run-time stage. Once the configuration stage is complete, the system executes the run-time stage in real-time to complete processing of an object for a printing device. By pre-calculating items during the configuration stage, the system reduces the execution time of the run-time stage in real-time. As a result, the performance of the microcontroller in real-time is enhanced.

Abstract: Provided is an image processing apparatus for improving efficiency of a clipping process. The image processing unit is an image processing apparatus for a raster image processor (RIP) mounted in an image forming apparatus. An order acquiring unit acquires instructions for image processing. A determination unit, in a case where clipping is set according to the instructions acquired by the order acquiring unit, determines whether that clipping is to be in an inclusive mode or an exclusive mode, and in a case of the exclusive mode, calculates pixels that are to be protected in a frame for which image processing is to be performed, and sets a number of pixels necessary for a clipping process. A clip processing unit, in the inclusive mode, in a case where a shape unit for which clipping is to be performed is a rectangle, performs clipping by evaluating a clipping area that includes the shape unit and a frame for which image processing is to be performed, and setting a different frame; and in a case where the shape unit is a trapezoid or a scan line, performs clipping by evaluating a positional relationship between the frame and a line being processed, and setting a different line; and in the exclusive mode, performs clipping by setting a number of pixels calculated by the determination unit without setting a different line, and performing evaluation of the clipping area and each line.
