Abstract
In a display controller, output surface data from a composition processing stageis received by and stored in a local latency hiding bufferof a memory write subsystembefore being written out to an external memory. The local bufferof the memory write subsystemsignals when it is 'full', and in response thereto the inputting of output surface data to the local bufferis stopped until the current line of the output surface has been finished, and then started again when the next line of the output surface begins. The writing of any data for the line of the output surface that was being written to the local bufferthat is already present in the local bufferand not yet written to the external memory is also skipped, and it is recorded that the output surface line in question is not properly stored in the external memory.
