ABSTRACT:
An improved printing machine, of the type in which image data, addresses and control data can be substantially concurrently transferred across multiple multipurpose buses, is provided. The printing machine comprises a first multipurpose bus adapted to substantially concurrently transfer a first set of the image data, addresses and control data and a second multipurpose bus adapted to substantially concurrently transfer a second set of the image data, addresses and control data. A module for processing the first and second sets of data communicates with the first and second multipurpose buses while a first discrete input/output module communicates with the first bus. Both the first processing module and the first discrete input/output module are adapted to transfer the first set of data between one another. A second discrete input/output module communicates with the second multipurpose bus and a third discrete input/output module communicates with the second multipurpose bus. both the second and third discrete input/output modules are adapted to transfer the second set of data between one another. Preferably, the first set of data can be transferred between the processing module and the first discrete input/output module substantially concurrent with the second set of data being transferred between the second discrete input/output module and the third discrete input/output module.
