MECHANISM TO INCREASE THREAD PARALLELISM IN A GRAPHICS PROCESSOR

摘要

A processing apparatus is described. The apparatus includes a plurality of execution threads having a first thread space configuration including a first plurality of rows of execution threads to process data in parallel, wherein each thread in a row is dependent on a top neighbor thread in a preceding row, partition logic to partition the plurality of execution threads into a plurality of banks, wherein each bank includes one or more of the first plurality of rows of execution threads and transform logic to transform the first thread space configuration to a second thread space configuration including a second plurality of rows of execution threads to enable the plurality of execution threads in each of the plurality of banks to operate in parallel.
