image forming apparatus |
| abstract |
The present invention relates to an image forming apparatus that distributes and transfers image data for one page using a plurality of DMA controllers without changing software or increasing the load on the CPU. When transferring the image data of one page, the transfer control unit (42b) of the data processing circuit unit (4) divides the size of the image data of one page of each color. The start address and size of the divided image data are set to a plurality of data transfer units (431 to 434) of the data processing circuit unit (4). The data transfer unit (431 to 434) reads out the divided image data of each color from the first memory (3) based on the start address and size of the divided image data of each color, and transfers it to the second memory (5) and to the transfer control unit (42b) Notify transfer completion. After that, when the transfer of the image data of one page is completed, the transfer control unit (42b) sends a completion notification to the main control unit (2). |
