Data processing device, method, chip and imaging box based on imaging box chip

Abstract

The invention provides a data processing device and method based on an imaging box chip, the chip and an imaging box. The chip comprises a volatile storage module and a nonvolatile storage module connected with the volatile storage module. ID of the chip is stored in the nonvolatile storage module. The data processing device comprises a communication module, an instruction analysis module, a judgement module and a data writing unit, wherein the communication module is used for being connected to a bus of imaging equipment and receiving an access instruction sent by the imaging equipment, and the access instruction carries a target ID; the instruction analysis module is connected with the communication module and used for analyzing whether the access instruction is a reading instruction or a writing instruction; the judgement module is connected with the communication module and used for judging whether the target ID is matched with the ID of the chip; and the data writing unit is connected with the instruction analysis module, the judgement module and the volatile storage module and used for writing data contents in the access instruction into the volatile storage module if the access instruction is the writing instruction before whether the target ID and the ID of the chip is matched or not is judged.

Description

technical field [0001] The invention relates to the technical field of printing and imaging, in particular to a data processing device, method, chip and imaging box based on an imaging box chip. Background technique [0002] Imaging equipment, such as printers, copiers, and fax machines, is used to image information to be imaged on media such as paper through ink, toner, and other imaging materials. An imaging device generally includes an imaging device main body and an imaging cartridge, which is usually detachably installed in the imaging device main body. In order to mark the consumption or residual information of the imaging material in the imaging box, a chip is often arranged on the imaging box, and the chip is usually installed on the imaging box in a detachable manner. The chip is usually provided with a non-volatile memory module, which is used to store rewritable data such as the consumption or remaining amount of the imaging material, and other read-only data rel...
