DATA PROCESSING APPARATUS, PRINTING SYSTEM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To efficiently process much data between a CPU and a GPU (Graphics Processing Unit).

SOLUTION: A data processing apparatus includes a device 3 capable of executing a plurality of processing asynchronously in parallel, and a host 2 for transmitting/receiving data between it and the device 3. The host 2 secures a memory area for performing data transfer between it and the device 3 in a system memory 12. The device 3 accesses the memory area and performs the data transfer in parallel while processing the data from the host 2. The host 2 divides data transferred to the device 3 into three or more, and writes the divided second data and the later in the memory area while the previous data is processed by the device 3.
