Processing apparatus for an inkjet printer

Abstract

A processing apparatus for an inkjet printer includes a bus. A processor runs a control program of the apparatus. A DMA controller is connected to the data bus to control address transfers in a number of channels. A control program memory is connected to the data bus to store the control program for access by the processor. A random access memory interface is connected to the data bus for access to image data for printing. Image processing circuitry is connected to the data bus to process the image data for printing. A printhead interface communicates with a printhead.
