  • Patent number: 10095962
    Abstract: A method for managing memory use in a graphics processing system receives a plurality of objects to be reproduced on an output medium, the output medium being divided into a plurality of bands. Objects falling within a band are stored in a corresponding local band memory and shared objects intersecting the band and at least one other band in at least one shared memory arena. Each shared memory arena is associated with a band counter defining the number of bands referencing said shared memory arena. The local band memory is associated with a data structure storing a shared memory arena identifier of the at least one shared memory arena where the shared objects intersecting the band are stored. The method facilitates release of the at least one shared memory arena in response to rasterizing the band selected for rasterizing based on the plurality of shared memory arena identifiers.
