    摘要: 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.

    摘要: A method and device for controlling bandwidth distribution through a switch fabric is provided wherein a plurality of line cards and processor cards are connected through a switch fabric for parallel processing of transmission requests, along with the provision of transmission “credits” allowing for transmitting additional data bytes during a given cycle, which provides efficient and speedy bandwidth distribution, as well as resolution of output contentions. The processors maintain a credit balance which allows flexibility in granting transmission requests to accommodate transmission scheduling and “bursty” transmissions. Processors on both of the line cards and the processor cards normalize the data transmission requirements for both inputs and outputs connected by the switch fabric. Smoothing of data transmission is provided using a time-weighted buffer.
