Abstract

A processor is provided for use with a marking material cartridge the processor having configurable logic for configuring the processor for use with an associated printing device. A print cartridge includes a housing defining a chamber for storing a marking material therein and a circuit on the housing. The circuit includes a memory portion storing data related to the marking material, an interface portion in operative communication with the associated printing device for communicating therewith, and a configurable execution unit including a network of gates which are programmable by first set of instruction primitives received into the circuit to define a first set of operation instructions executable by the execution unit during operation of the print cartridge of the associated printing device. A method is provided for adapting a print cartridge for use with a printer including providing a processor having configurable logic on the print cartridge, and configuring the configurable logic of the processor for operative compatibility with the printer. In one form, the configurable logic processor is a programmable logic device which is configured by opening fusible links between logical gates contained in the programmable logic device.
