Physics processing unit Wikipedia. A physics processing unit PPU is a dedicated microprocessor designed to handle the calculations of physics, especially in the physics engine of video games. Examples of calculations involving a PPU might include rigid body dynamics, soft body dynamics, collision detection, fluid dynamics, hair and clothing simulation, finite element analysis, and fracturing of objects. The idea is that specialized processors offload time consuming tasks from a computers CPU, much like how a GPU performs graphics operations in the main CPUs place. The term was coined by Ageia to describe its Phys. X chip. Several other technologies in the CPU GPU spectrum have some features in common with it, although Ageias product was the only complete one designed, marketed, supported, and placed within a system exclusively as a PPU. HistoryeditAn early academic PPU research project12 named SPARTA Simulation of Physics on A Real Time Architecture was carried out at Penn State3 and University of Georgia. This was a simple FPGA based PPU that was limited to two dimensions. This project was extended into a considerably more advanced ASIC based system named HELLAS. February 2. 00. 6 saw the release of the first dedicated PPU Phys. Minecraft Account. X from Ageia later merged into n. Vidia. The unit is most effective in accelerating particle systems, with only a small performance improvement measured for rigid body physics. The Ageia PPU is documented in depth in their US patent application 2. NvidiaAgeia no longer produces PPUs and hardware acceleration for physics processing is now supported through some of their graphics processing units. AGEIA Phys. XeditThe first processor to be advertised as a PPU was called the Phys. X chip, introduced by a fabless semiconductor company called AGEIA. Games wishing to take advantage of the Phys. X PPU must use AGEIAs Phys. XSDK, formerly known as the Novode. X SDK. It consists of a general purpose RISC core controlling an array of custom SIMD floating point VLIW processors working in local banked memories, with a switch fabric to manage transfers between them. There is no cache hierarchy as in a CPU or GPU. Download Deutsch drivers for NVIDIA hardware ,. Version 9. 16. 0318 Freigabedatum 2016. Betriebssystem Windows Vista 64bit, Windows 8, Windows 8.

X was available from three companies akin to the way video cards are manufactured. ASUS, BFG Technologies,6 and ELSA Technologies were the primary manufacturers. PCs with the cards already installed were available from system builders such as Alienware, Dell, and Falcon Northwest. In February 2. Download Japanese drivers for NVIDIA hardware ,. Ageia Drivers Html' title='Ageia Drivers Html' />A physics processing unit PPU is a dedicated microprocessor designed to handle the calculations of physics, especially in the physics engine of video games. PhysX is a scalable multiplatform game physics solution supporting a wide range of devices, from smartphones to highend multicore CPUs and GPUs. PhysX is already. Nvidia bought Ageia Technologies and eventually cut off the ability to process Phys. X on the AGEIA PPU and NVIDIA GPUs in systems with active ATiAMD GPUs, it seemed that Phys. X went 1. 00 to Nvidia. But in March 2. 00. Nvidia announced that it will make Phys. X an open standard for everyone,8 so the main graphic processor manufacturers will have Phys. X support in the next generation graphics cards. Nvidia announced that Phys. X will also be available for some of their released graphics cards just by downloading some new drivers. See physics engine for a discussion of academic research PPU projects. Phys.

Havok FXeditThe Havok SDK is a major competitor to the Phys. X SDK. Used in more than 1. Half Life 2, Halo 3 and Dead Rising. To compete with the Phys. X PPU, an edition known as Havok FX was to take advantage of multi GPU technology from ATI Cross. Fire and NVIDIA SLI using existing cards to accelerate certain physics calculations. Havok divides the physics simulation into effect and gameplay physics, with effect physics being offloaded if possible to the GPU as Shader Model 3. CPU as normal. The important distinction between the two is that effect physics do not affect gameplay dust or small debris from an explosion, for example the vast majority of physics operations are still performed in software. This approach differs significantly from the Phys. X SDK, which moves all calculations to the Phys. X card if it is present. Since Havoks acquisition by Intel, Havok FX appears to have been shelved or cancelled. Vs. GPUseditThe drive toward GPGPU has made GPUs more suitable for the job of a PPU DX1. Modern GPUs support compute shaders, which run across an indexed space and dont require any graphical resources, just general purpose data buffers. NVidia CUDA provides a little more in the way of inter thread communication and scratchpad style workspace associated with the threads. Nonetheless GPUs are built around a larger number of longer latency, slower threads, and designed around texture and framebuffer data paths, and poor branching performance this distinguishes them from PPUs and the Cell as being less well optimized for taking over game world simulation tasks. The Codeplay Sieve compiler supports the PPU, indicating that the Ageia phys. X chip would be suitable for GPGPU type tasks. However Ageia seem unlikely to pursue this market. Intel Xeon PhieditLike the Cell, Xeon Phi sits between the CPU and the GPU, in the spectrum between, general purpose processing versus specialized high performance back end processing. This uses caches rather than scratchpads, but still manages to achieve high throughput. AMD have declared their long term intention to enable AMD APUs to use Radeon as a vector co processor, sharing resources such as cache hierarchy. This future configuration started materializing in the form of Heterogeneous System Architecture. PS2 VU0editAlthough very different from the Phys. X, one could argue the Play. Station 2s VU0 is an early, limited implementation of a PPU. Conversely, one could describe a PPU to a PS2 programmer as an evolved replacement for VU0. Its feature set and placement within the system is geared toward accelerating game update tasks including physics and AI it can offload such calculations working off its own instruction stream whilst the CPU is operating on something else. Being a DSP however, it is much more dependent on the CPU to do useful work in a game engine, and would not be capable of implementing a full physics API, so it cannot be classed as a PPU. Also VU0 is capable of providing additional vertex processing power, though this is more a property of the pathways in the system rather than the unit itself. This usage is similar to Havok FX or GPU physics in that an auxiliary units general purpose floating point power is used to complement the CPU in either graphics or physics roles.
