ABSTRACT:
A method, apparatus, and computer implemented instructions for managing a set of memory resources used to store texture objects in a data processing system. A texture manager allocates memory to a current texture object in a set of memory resources. A stored texture object, handled by the texture manager, is selectively removed in response to an inability to allocate sufficient memory to the current texture object. The allocating and selectively removing steps are repeated until the current texture object is allocated sufficient memory. The repeating step is halted in response to an absence of any stored texture objects, handled by a texture manager, being present in the first memory resource. Stored texture objects, handled by another texture manager, are selectively removed in response to an inability to allocate sufficient memory to the current texture object. Memory is allocated in the set of memory resources to the current texture object in response to selectively removing stored texture objects.
