Retrieved November 30, By giving away the engine and promoting it to developers, AGEIA is trying to create a large software base that will lend itself well to PPU hardware sales. 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. In many of today’s games, objects just don’t seem to act the way you’d want or expect them to in real life. Portions of PhysX processing actually run on both the CPU and GPU, leveraging the best of both architectures to deliver the best experience to the user. 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.

PhysX is a multi-threaded physics simulation SDK. The PhysX chip will support up to 32, rigid bodies, all interacting with each other, he said.
This uses caches rather than scratchpadsbut still manages to achieve high throughput. They are essentially increasing the power that both other components effectively have and also pushes them beyond their limits.
Retrieved April 6, Gamers will similarly enable physics on their GPUs so long as frame rates remain playable. The highly tuned multi-core processor accelerates real-time physical motion and interaction. If the small startup can pull off its grand vision, the company will add a new category to the PC: Views Read Edit View history.
In response to the Real World Technologies analysis, Mike Skolones, product manager of PhysX, said  that SSE support had been left behind because most games are developed for consoles first and then ported to the PC. However Ageia seem unlikely to pursue this market. Berardini April 12, The drive toward GPGPU has made GPUs more suitable for the job of a PPU; DX10 added integer data types, unified shader architecture, and a geometry shader stage which allows a broader range of algorithms to be implemented; Modern GPUs support compute shaders, which run across an indexed space and don’t require any graphical resources, just general purpose data buffers.
Getting past the business side of things, we have learned a bit more about the PhysX hardware and software than we have written in previous articles. The company hopes to release the chip in time for the Christmas holidays, along with five to fifteen games that will take advantage of the technology, executives said in an interview Tuesday afternoon.
Physics processing unit
physcis The PhysX was available from three companies akin to the way video cards are manufactured. Because of the complex interactions between the graphics chip and the PhysX physics engine, Ageia executves said they expect that sales of PhysX chips and high-end graphics cards will go hand in hand.
As one of the handful of major physics engines, it is used in many games, such as The Witcher 3: Arkham KnightBorderlands 2etc.
Examples of calculations involving a PPU might include rigid body dynamicssoft body dynamicscollision detectionfluid dynamicshair and clothing simulationfinite element analysisand fracturing of objects. To my suprise, it actually worked, however you may have trouble acquiring the drivers for it as Nvidia dropped the drivers from their recent PhysX redist packages.
These represent an environment that’s much different than a general purpose CPU.

A physics processing unit PPU is a dedicated microprocessor designed to handle the calculations of physicsespecially in the physics engine of video games. Founded inthe startup has been working on the chip and the related technology for three years.
Imagine that you have a wall of a castle raining down on your filthy, peasant head in a 3D, physics enhanced Trogdor game.

Retrieved November 3, Archived from the original on November 9, All the physics calculations are being done on the PPU but now the CPU has to deal with an additional objects that AI and must avoid or deal with.
