Abstract
A recording apparatus for recording with use of a recording head having two nozzle arrays arranged side-by-side includes first, second, and third direct memory access (DMA) units, a data converter unit for converting first image data stored in a work buffer into second image data, a record buffer unit for storing the second image data, a latch unit for storing the second image data in a transfer buffer, a buffer reading control table unit, and a DMA control unit for causing transfer processing to be executed by the first, second, and third DMA units based on a flag in the buffer reading control table unit when the image data stored in the work buffer is transferred to the transfer buffer.
