FPGA – это сокращение от английского словосочетания Field Programmable Gate Array. ПЛИС – это сокращение от словосочетания «Программируемая Логическая Интегральная Схема». Слово ПЛИС встречается в русскоязычных документациях и описаниях вместо слова FPGA. Далее по тексту в основном будет использоваться этот термин - ПЛИС.  Микросхемы ПЛИС – это не микропроцессоры, в которых пользовательская программа выполняется последовательно, команда за командой. В ПЛИС реализуется именно электронная схема, состоящая из логики и триггеров. Проект для ПЛИС может быть разработан, например, в виде принципиальной схемы. Want to run Linux with RISC-V on Open Source Hardware?  I will also discuss the important of free software FPGA tools like yosys for synthesis, and nextpnr for place and route, and how SymbiFlow is leveraging bitstream documentation from Project IceStrom. Чтобы Hardware стало Open — нужно чтобы все эти компоненты распространялись под свободной лицензией. Конечно, для чертежей могут не подойти обычные лицензии, используемые для СПО, потому они должны быть соответствующим образом адаптированы. Теперь по пунктам  Для отладки используют FPGA, часто сложные проекты привязаны к определённой отладочной плате, что не очень хорошо, нужно бы придумать способ сделать код универсальным. Процесс ясен — написал на Verilog или VHDL сдвиговый регистр, синтезировал (кстати, какие форматы файлов на данном этапе используются?) отдал на завод и сказал, мол, хочу это в SO, потом тебе отгружают чипы.

A physics processing unit PPU is a dedicated microprocessor designed to handle the calculations of physicsespecially in the physics engine of video Open Hardware Bench Queue open hardware fpga queue. It is an example of hardware acceleration.

Examples of calculations involving a PPU might include rigid body dynamicssoft body dynamicscollision detectionfluid dynamicshair and clothing simulationfinite open hardware fpga queue analysisand fracturing of open hardware fpga queue. The term was coined by Ageia to describe its PhysX chip. Several other technologies in the CPU-GPU spectrum have some features open hardware fpga queue common with it, although Ageia's product was the only complete one designed, marketed, supported, and placed within a system exclusively as a PPU.

The unit is most effective in accelerating particle systemswith only a small performance improvement measured for rigid body physics. The PhysX was available from three companies akin to the way video cards are manufactured. PCs with the cards already installed were available open hardware fpga queue system builders such as AlienwareDelland Falcon Northwest.

But in MarchNvidia announced that it will make PhysX an open standard for everyone, [8] so the main graphic-processor manufacturers will have PhysX support in the next generation graphics cards. Nvidia announced that PhysX 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. Havok divides the physics simulation into effect and gameplay physics, with effect physics being offloaded if possible to the GPU as Shader Model 3. 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.

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. 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 Cell as being less well optimized for taking over game world simulation tasks.

However Ageia seem unlikely to pursue this market. This uses caches rather than scratchpads open hardware fpga queue, but still manages to achieve high throughput.

This future configuration started materializing in the form of Heterogeneous System Architecture. Its feature-set and placement within the Open Hardware Watch Queue system is geared toward accelerating game update tasks including physics and AI; open hardware fpga queue can offload such calculations working off its own instruction stream whilst the CPU is operating on something else.

Also VU0 is capable open hardware fpga queue 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 unit's general purpose floating point open hardware fpga queue is used to complement the CPU in either graphics or physics roles.
