    • 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。

    • A PPU-enhanced computer system is provided including a Physics Processing Unit (PPU), a Graphics Processing Unit (GPU), a Central Processing Unit (CPU) and a main memory, wherein the system creates an animation from application data stored in the main memory by data communication between the GPU, PPU, CPU and main memory. The system may include a memory controller and a chip set connecting the bus structure to the CPU and GPU through an I/O interface and connecting the PPU though a bus structure. The PPU may be a separate processing core logically grouped with the CPU and GPU processing cores. In this preferred embodiment, the CPU, GPU and PPU receive data from a common L2 cache and/or a main system memory.
