Abstract
A communication I/F of an image generating unit writes settings for an image data to a transitory storage unit by serial communication before the image data is transmitted from the image generating unit to the transitory storage unit. The communication I/F stores partial information of an address used for previous writing in a cache unit, and omits the writing of the partial information of the address used for further writing if the partial information of the address matches the partial information of the stored address.
Claims8
An image forming apparatus comprising:
- an image generating unit generating image data;
- an image forming unit controlling a formation of image based on the image data;
- a storing circuit arranged between the image generating unit and the image forming unit, and temporarily storing the image data;
- and
- a serial interface writing a setting of the image data in the storing circuit, wherein the serial interface stores partial information of an address used in previous writing, and omits writing partial information of an address used for further writing if the partial information of the address used for further writing matches the partial information of the address used in the previous writing.

A control method for controlling an image forming apparatus including
- an image generating unit generating image data, an image forming unit controlling a formation of image based on the image data, a storing circuit arranged between the image generating unit and the image forming unit and temporarily storing the image data, and a serial interface writing a setting of the image data in the storing circuit, the control method comprising:
- storing, by the serial interface, partial information of an address used in previous writing;
- and
- omitting, by the serial interface, writing partial information of an address used for further writing if the partial information of the address used for further writing matches the partial information of the address used in the previous writing.
