The Open Graphics Project (OGP) was founded with the goal to design an open-source hardware / open architecture and standard for graphics cards, primarily targeting free software / open-source operating systems. The project created a reprogrammable development and prototyping board and had aimed to eventually produce a full-featured and competitive end-user graphics card.
The project's first product was a PCI graphics card dubbed OGD1, which used a field-programmable gate array (FPGA) chip. Although the card did not have the same level of performance or functionality as graphics cards on the market at the time, it was intended to be useful as a tool for prototyping the project's first application-specific integrated circuit (ASIC) board, as well as for other professionals needing programmable graphics cards or FPGA-based prototyping boards. It was also hoped that this prototype would attract enough interest to gain some profit and attract investors for the next card, since it was expected to cost around US$2,000,000 to start the production of a specialized ASIC design. PCI Express and/or Mini-PCI variations were planned to follow. The OGD1 began shipping in September 2010, [1] some six years after the project began and 3 years after the appearance of the first prototypes. [2]
Full specifications will be published and open-source device drivers will be released. All RTL will be released. Source code to the device drivers and BIOS will be released under the MIT and BSD licenses. The RTL (in Verilog) used for the FPGA and the RTL used for the ASIC are planned to be released under the GNU General Public License (GPL).
It has 256 MiB of DDR RAM, is passively cooled, and follows the DDC, EDID, DPMS and VBE VESA standards. TV-out is also planned.
Versioning schema for OGD1 will go like this:
{Root Number} – {Video Memory}{Video Output Interfaces}{Special Options e.g.: A1 OGA firmware installed}
Field | Example Value | Example Description |
---|---|---|
Root number | OGD1P- | OGD1 board with PCI Bus |
Video memory | 256 | 256 MiB |
Video outputs, in order, skip any not installed | ||
First interface | D | Dual-link DVI |
Second interface | D | Dual-link DVI |
Third interface | A | Analog video, 75 ohm, VGA compatible |
Fourth interface | V | TV video |
Special options, in alphanumeric order, each preceded by a dash | ||
Factory firmware-RTL | A1 | OGA1 Firmware |

The OGP project failed to gain the necessary funding to produce an ASIC version of its card. The project appears to have been discontinued in 2011.
A field-programmable gate array (FPGA) is a type of configurable integrated circuit that can be programmed or reprogrammed after manufacturing. FPGAs are part of a broader set of logic devices referred to as programmable logic devices (PLDs). They consist of an array of programmable logic blocks and interconnects that can be configured to perform various digital functions. FPGAs are commonly used in applications where flexibility, speed, and parallel processing capabilities are required, such as in telecommunications, automotive, aerospace, and industrial sectors.
A motherboard is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general use.
In computing, an expansion card is a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer's motherboard to add functionality to a computer system. Sometimes the design of the computer's case and motherboard involves placing most of these slots onto a separate, removable card. Typically such cards are referred to as a riser card in part because they project upward from the board and allow expansion cards to be placed above and parallel to the motherboard.
A system on a chip or system-on-chip is an integrated circuit that integrates most or all components of a computer or other electronic system. These components almost always include on-chip central processing unit (CPU), memory interfaces, input/output devices and interfaces, and secondary storage interfaces, often alongside other components such as radio modems and a graphics processing unit (GPU) – all on a single substrate or microchip. SoCs may contain digital and also analog, mixed-signal and often radio frequency signal processing functions.
A graphics card is a computer expansion card that generates a feed of graphics output to a display device such as a monitor. Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to integrated graphics processor on the motherboard or the CPU. A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym "GPU" is sometimes also used to erroneously refer to the graphics card as a whole.
In a computer system, a chipset is a set of electronic components on one or more integrated circuits that manages the data flow between the processor, memory and peripherals. The chipset is usually found on the motherboard of computers. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance.
Octane series of IRIX workstations was developed and sold by SGI in the 2000s. Octane and Octane2 are two-way multiprocessing-capable workstations, originally based on the MIPS Technologies R10000 microprocessor. Newer Octanes are based on the R12000 and R14000. The Octane2 has four improvements: a revised power supply, system board, and Xbow ASIC. The Octane2 has VPro graphics and supports all the VPro cards. Later revisions of the Octane include some of the improvements introduced in the Octane2. The codenames for the Octane and Octane2 are "Racer" and "Speedracer" respectively.
The Voodoo 5 was the last and most powerful graphics card line that 3dfx Interactive released. All members of the family were based upon the VSA-100 graphics processor. Only the single-chip Voodoo 4 4500 and dual-chip Voodoo 5 5500 made it to market.
Number Nine Visual Technology Corporation was a manufacturer of video graphics chips and cards from 1982 to 1999. Number Nine developed the first 128-bit graphics processor, as well as the first 256-color (8-bit) and 16.8 million color (24-bit) cards.
AMD CrossFire is a brand name for the multi-GPU technology by Advanced Micro Devices, originally developed by ATI Technologies. The technology allows up to four GPUs to be used in a single computer to improve graphics performance.
In integrated circuit design, hardware emulation is the process of imitating the behavior of one or more pieces of hardware with another piece of hardware, typically a special purpose emulation system. The emulation model is usually based on a hardware description language source code, which is compiled into the format used by emulation system. The goal is normally debugging and functional verification of the system being designed. Often an emulator is fast enough to be plugged into a working target system in place of a yet-to-be-built chip, so the whole system can be debugged with live data. This is a specific case of in-circuit emulation.
The G400 is a video card made by Matrox, released in September 1999. The graphics processor contains a 2D GUI, video, and Direct3D 6.0 3D accelerator. Codenamed "Toucan", it was a more powerful and refined version of its predecessor, the G200.

Sam440, also known by Sam or its codename Samantha, is a line of modular motherboards produced by the Italian company ACube Systems Srl. The Sam440ep version is a motherboard based on the PowerPC 440EP system-on-a-chip processor which includes a double-precision FPU. It is made by AMCC. Their primary targets are the industrial and embedded markets, running operating systems such as Linux and AmigaOS 4.
The NetFPGA project is an effort to develop open-source hardware and software for rapid prototyping of computer network devices. The project targeted academic researchers, industry users, and students. It was not the first platform of its kind in the networking community. NetFPGA used an FPGA-based approach to prototyping networking devices. This allows users to develop designs that are able to process packets at line-rate, a capability generally unafforded by software based approaches. NetFPGA focused on supporting developers that can share and build on each other's projects and IP building blocks.
The graphics processing unit (GPU) codenamed Radeon R600 is the foundation of the Radeon HD 2000 series and the FireGL 2007 series video cards developed by ATI Technologies. The HD 2000 cards competed with nVidia's GeForce 8 series.
ATI released the Radeon X300 and X600 boards. These were based on the RV370 and RV380 GPU respectively. They were nearly identical to the chips used in Radeon 9550 and 9600, only differing in that they were native PCI Express offerings. These were very popular for Dell and other OEM companies to sell in various configurations; connectors: DVI vs. DMS-59, card height: full-height vs. half-height.
The Radeon 400 series is a series of graphics processors developed by AMD. These cards were the first to feature the Polaris GPUs, using the new 14 nm FinFET manufacturing process, developed by Samsung Electronics and licensed to GlobalFoundries. The Polaris family initially included two new chips in the Graphics Core Next (GCN) family. Polaris implements the 4th generation of the Graphics Core Next instruction set, and shares commonalities with the previous GCN microarchitectures.
