  • Method of managing memory allocation in a printing system
    Patent number: 5717842
    Abstract: A method of managing memory allocation in a printing system including the steps of creating a plurality of blocks and designating each block with an identifier. In response to a request from a client, a first set of identifiers, corresponding with a first set of blocks, is placed into a database by a resource manager. The client then accesses the database and, by reference to the first set of identifiers, begins filling up the first set of blocks with image data. As each block is filled, the client transmits an interrupt signal to a controller. After a predesignated one of the first set of blocks has been filled, the controller causes the resource manager to place a second set of identifiers in the database so that the client can access the second set of identifiers as soon as it has completed filling the first set of blocks.
