Abstract:
1. An ink jet recording apparatus for recording data using a recording head, comprising: a work buffer means for storing first image data received from a host device; at least one transfer buffer means for storing second image data which is to be transferred to the recording head; a data converting means for converting the first image data stored in said work buffer means into the second image data; a first direct memory access means for transferring the first image data from said work buffer means to said data converting means; at least one record buffer means for storing the second image data; a second direct memory access means for transferring the second image data from said data converting means to said record buffer means; a latch means for storing the second image data which is to be stored in said transfer buffer means; a third direct memory access means for transferring the second image data from said record buffer means to said latch means; a buffer reading control table means for said work buffer means to which a flag corresponding to data of said work buffer means is written; and a direct memory access control means for causing transfer processing to be executed by said first, second, and third direct memory access means based on the flag when the image data stored in said work buffer means is transferred to said transfer buffer means.
