Abstract: A method of providing physics data within a game program or simulation using a hardware-based physics processing unit having unique architecture designed to efficiently calculate physics related data.

Abstract: An integrated circuit comprises an external memory, a plurality of parallel connected Vector Processing Engines (VPEs), and an External Memory Unit (EMU) providing a data transfer path between the VPEs and the external memory. Each VPE contains a plurality of data processing units and a message queuing system adapted to transfer messages between the data processing units and other components of the integrated circuit.

Abstract: 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.

Abstract: Embodiments of a callback procedure mechanism and method are disclosed in relation to a system running a physics simulation in parallel with a main application. A main application registers callback procedures in memory shared with the physics simulation in response to data generated by the physics simulation. The callback procedures are executed by the physics simulation with data generated by the physics simulation.

Abstract: A PPU enhanced system stores software packages implementing, at least in part, a physics subroutine. The package being implemented as a plurality of modules, at least one module being stored and executed on a host system and another module being stored and executed on the PPU.

Abstract: 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.

Abstract: The invention relates to a process and composition for trapping coloring or non-coloring liquids, in a non-woven textile consisting of fibers, characterized in that said textile is metallized under vacuum by spraying metal particles onto at least one face of the textile and along a portion of its thickness in such a way that the surface fibers, or those in the immediate vicinity of the surface, are coated with metal while remaining independent of each other.
