A decomposing apparatus is provided for use in a printing machine of the type adapted to receive a first set of information written in a printer page description language and a second set of information written in a printer page description language. The decomposing apparatus preferably includes: an arrangement for parsing the first set of information into a first set of image related components during a first time interval and the second set of information into a second set of image related components during a second time interval; and, an arrangement for performing image related operations on selected components of the first set of image related components, the image related operations being performed on the first set of image related components during the second interval so that the image related operations can be performed on the first set of image related components substantially concurrently with the second set of information being parsed.

Apparatus and method for multi-stage/multi-process decomposing

A realtime control process for an electronic reprographic system in which background and job requests are dynamically partitioned into unique combinations of virtual machines for carrying out each request, with each virtual machine having certain system services to carry out the function provided by the virtual machine.

Control for electronic image processing systems

A state controller for an electronic reprographic system for controlling system operations when processing requests in which the system has a plurality of hardware and software system components providing discrete services for processing requests and maintaining operation of the system, and job programming means including a display screen for inputting requests, including: a state holder for monitoring the current operating state of the system components; plural discrete job processing virtual machines with each of the virtual machines having at least one service associated with it for implementing the virtual machine; each of the services having at least one of the system components for carrying out the service; and a scheduler for managing resources of and setting priorities for the virtual machines to process the requests in an efficient manner, the scheduler being adapted to cause memory from a first one of the virtual machines to be distributed to a second one of the virtual machines when the second one of the virtual machines requests more memory than is normally allocated to it.
