摘要： Disclosed is a printing apparatus in which printing elements used in the printing of each raster can be set at will. The printing apparatus has a carriage equipped with a printhead having a plurality of printing elements arranged in a predetermined direction, and the carriage is made to scan across a printing medium in a direction that intersects the direction in which the printing elements are arranged, thereby performing printing on the medium. The printing elements are divided into a plurality of blocks each consisting of a predetermined number of successive printing elements, print data that has been transmitted in raster form is stored in a receive buffer, and data that has been stored in the receive buffer is divided and stored in a print buffer having a plurality of areas corresponding to the blocks of printing elements. In accordance with printing elements used in a scan, the data in a corresponding area of the print buffer is shifted and the areas of the print buffer and respective ones of the blocks are made to correspond in accordance with distance over which the printing medium is transported after a scan is performed. The amount of shift is then calculated.

摘要： A motor control apparatus has a motor driver for driving a motor in accordance with an input of digital-format drive data of a predetermined length, thereby driving a mechanism using the motor as a power source. The drive data, which has been made to correspond to a plurality of drive patterns, is stored in a memory, part of the drive data, which has been read out from the memory by DMA, is replaced with other data, and the resultant data is output to the motor driver. Thus, different drive data can be generated by replacing a part of the drive data stored in the memory with other data, and the generated data can be transferred to the motor driver. This makes it possible to reduce the memory capacity needed for motor control.

摘要： A CPU that has transferred to a stop mode in order to reduce power consumption can be restarted from a control section of a printer, but cannot be restarted by an instruction from a host computer. The printer according to the present invention includes an interface control section for communicating with the host computer; a CPU having a mode in which the CPU is on standby in a low power consumption state; and a clock control section supplying a clock signal. The clock control section supplies a clock signal only to the interface control section when the CPU transfers to the stop mode.

摘要： An inkjet recording apparatus in which displacements of dots are reduced. In the inkjet recording apparatus, recording data is read out from a recording buffer at a period corresponding to a second resolution. The apparatus determines whether or not to delay the timing at which the readout is performed by an interval corresponding to one-half of the period corresponding to a first resolution. The apparatus also selects whether to drive an inkjet head in a front half or a last half of the period corresponding to the first resolution.

摘要： A DMA controller arbitrates and selects a DMA control information signal received from at least one of a plurality of DMA request blocks and accesses an SDRAM on the basis of the selected DMA control information signal. In the DMA controller, an SDRAM controller detects using a detector the number of possible sequential accesses on the basis of a DMA start address signal, compares using a comparator this number of possible sequential accesses with the burst DMA request number designated by a BSTNUM signal, selects not larger one of the two numbers, and sets the number of sequential DMAs to be actually executed to the selected number. Accordingly, with a simple configuration, sequential access is made possible starting from an arbitrary address.
