ABSTRACT:
A graphics processing apparatus includes an output pipeline including a set of memory clients. The graphics processing apparatus also includes a memory controller connected to the output pipeline. The memory controller is configured to retrieve data requested by respective ones of the memory clients from a memory. The graphics processing apparatus further includes a buffering module connected between the memory controller and the output pipeline. The buffering module includes a buffer including a buffering space shared by the memory clients. The buffering module also includes a buffer controller connected to the buffer. The buffer controller is configured to: (1) dynamically assign portions of the buffering space to respective ones of the memory clients; (2) coordinate storage of the data in the assigned portions; and (3) coordinate delivery of the data from the assigned portions to respective ones of the memory clients.
