    • A system for performing data-parallel operations and task-parallel operations. A first switch fabric node (SFN) includes first and second lane processing engines (LPEs). The first LPE includes a first set of lane processing units (LPUs) configured to perform data-parallel operations, where each LPU performs a set of operations, and each LPU uses a different set of data for the set of operations, and each LPU within the first set of LPUs uses a different set of data for the set of operations. The second LPE includes a second set of LPUs configured to perform task-parallel operations, where each LPU performs a different set of operations. A processing control engine (PCE) is configured to distribute instructions and data to the first LPE and the second LPE. Advantageously, data parallel operations and task parallel operations are able to be performed on the same processor simultaneously.
    • 用于执行数据并行操作和任务并行操作的系统。 第一交换机节点(SFN)包括第一和第二通道处理引擎(LPE)。 第一LPE包括配置成执行数据并行操作的第一组通道处理单元(LPU),其中每个LPU执行一组操作,并且每个LPU对于该组操作使用不同的一组数据,并且每个LPU在 第一组接口板使用不同的数据集作为该组操作。 第二LPE包括被配置为执行任务并行操作的第二组LPU,其中每个LPU执行不同的操作集合。 处理控制引擎(PCE)被配置为将指令和数据分发到第一LPE和第二LPE。 有利地,数据并行操作和任务并行操作能够同时在同一处理器上执行。

    • One embodiment of the invention sets forth a hardware-based physics processing unit (PPU) having unique architecture designed to efficiently generate physics data. The PPU includes a PPU control engine (PCE), a data movement engine and a floating point engine (FPE). The PCE manages the overall operation of the PPU by allocating memory resources and transmitting graphics processing commands to the FPE and data movement commands to the DME. The FPE includes multiple vector processors that operate in parallel and perform floating point operations on data received from a host unit to generate physics simulation data. The DME facilitates the transmission of data between the host unit and the FPE by performs data movement operations between memories internal and external to the PPU.
    • 本发明的一个实施例阐述了一种基于硬件的物理处理单元(PPU),其具有设计成有效地生成物理数据的独特架构。 PPU包括PPU控制引擎(PCE),数据移动引擎和浮点引擎(FPE)。 PCE通过分配内存资源并向FPE发送图形处理命令和向DME发送数据移动命令来管理PPU的整体操作。 FPE包括并行操作的多个矢量处理器,并对从主机单元接收的数据进行浮点运算,以产生物理模拟数据。 DME通过在PPU内部和外部的存储器之间执行数据移动操作来促进主机和FPE之间的数据传输。
