    • This disclosure describes techniques for extending the architecture of a general purpose graphics processing unit (GPGPU) with parallel processing units to allow efficient processing of pipeline-based applications. The techniques include configuring local memory buffers connected to parallel processing units operating as stages of a processing pipeline to hold data for transfer between the parallel processing units. The local memory buffers allow on-chip, low-power, direct data transfer between the parallel processing units. The local memory buffers may include hardware-based data flow control mechanisms to enable transfer of data between the parallel processing units. In this way, data may be passed directly from one parallel processing unit to the next parallel processing unit in the processing pipeline via the local memory buffers, in effect transforming the parallel processing units into a series of pipeline stages.
    • 本公开描述了用于利用并行处理单元来扩展通用图形处理单元(GPGPU)的架构以允许基于流水线的应用的有效处理的技术。 这些技术包括配置连接到作为处理流水线的阶段的并行处理单元的本地存储器缓冲器,以保持用于在并行处理单元之间传送的数据。 本地存储缓冲器允许并行处理单元之间的片上,低功耗,直接数据传输。 本地存储器缓冲器可以包括基于硬件的数据流控制机制,以使得能够在并行处理单元之间传送数据。 以这种方式,数据可以经由本地存储器缓冲器直接从一个并行处理单元传递到处理流水线中的下一个并行处理单元,实际上将并行处理单元转换成一系列流水线级。
