Single Read Composer with Outputs

摘要

A processing unit for generating multiple output items for output to a display or encoder. The processing unit may include a memory that stores data that will be used by a composer to generate the multiple output items. The processing unit may include a composer that executes only a single memory read operation when obtaining the data and splits the data to generate the multiple output items. The composer also may perform a function on the data before the data is split if all of the multiple output items require the data to undergo this function. The processing unit may also include a number of output buffers that each receive an output item from the composer and deliver the output item to an output such as a display or encoder.
