Abstract
A digital image printer that performs certain digital image processing functions using parallel integrated circuitry and other functions using serial integrated circuitry in an effort to minimize integrated circuit real estate. The serial integrated circuitry is allocated to certain functions within digital image printing system that perform various mechanical operations. The inherent mechanical time constant of these mechanical operations, when compared to electrical digital image processing operations performed using modern integrated circuitry, is relatively long. In other words, the mechanical operations are performed in a relatively longer time than is made possible using modern integrated circuitry and processors employed within digital image printing systems. The present invention dedicates certain of the functions used to perform digital image processing to be performed using slower, serial integrated circuitry. While this serial digital image processing is slow when compared to parallel digital image processing, there are advantages in the particular context of digital image printing systems, in that, serial processing integrated circuitry takes up significantly less space…
