觉得仅仅去破解修改NVIDIA、ATI的驱动太过小儿科了?现在有够你玩的.Traversal公司推出了一款开源显卡,允许用户为它编制各种程序,实现任何你所需要的功能.
该卡的真正名称应该叫FPGA开发平台套装,采用PCI/PCI-X接口,主芯片为Xilinx Spartan-III XC3S4000 FPGA可编程逻辑阵列芯片,被动散热.卡上还包括Lattice LFXP10非易失性FPGA,四颗Silicon Image SiI178双连接DVI芯片,飞利浦TDA8777 Triple 330MHz 10-bit视频DAC和Conexant CX25874视频编码器,板载256MB 128bit DDR400显存.提供两个双连接DVI接口,一个RGB模拟接口和S-Video、合成视频输出.

• S-Video and composite video outputs
• 1 RGB analog video output (max resolution:2048x1536@70Hz)
• 2 DVI dual link video outputs (max resolution: 2560x1600@60Hz)
• 66 user I/O signals on a 92-pin Hirose connector
• 68 user I/O signals on an available 100-pin IDC connector
• 128 bit memory bus
• Free^[*] Hardware Design (schematics)
• Active Community Support
• Free^[*] Design PCI core
• RoHs Compliant
• Passive Cooling

Hardware Specification:

• PCI/PCI-X (33/64-bit, 33-133MHz) card edge
• 256 MiB DDR400 (200Mhz) graphics memory
• Lattice® LFXP10 non-volatile FPGA (data sheet)
• Xilinx® Spartan™-III XC3S4000 FPGA (data sheet)
• 4 Silicon Image™ SiI178 Dual Link DVI Transmitters
• Philips TDA8777 Triple 330Mhz 10-bit video DAC (data sheet)
• Conexant™ CX25874 Video Encoder
• Dimensions: 6.875in x 4.2in
• Power Consumption: ~20 watts

当然,这块卡主要针对那些学习FPGA编程的学生,需要视频开发平台的工程师以及专业程度相当高的爱好者.不过毕竟这样的FPGA平台开发自由度相当高,普通用户未来可能看到基于该平台,拥有独特功能的显卡产品.

当前开始预订的OGD1开源显卡开发平台售价为1500美元,预订可获100美元折扣.
