FPGA_VIP_V101 has been introduced for more than half a year, the functions of the routine has been transplanted, the main reference Crazybingo routines for porting and the development of a combination of board design a few instances of the routineMainly includes:Hardware configuration:FPGA:EP4CE6E22C8N (6k logical resource, can be nios developed)sdram:hy57v641620 (32M, can do video image cache, Nios memory)Communication interface: 1, USB2.0 (68013 high-speed data communication) 2, USB2.0 (cp2102

1. Several termsVGA, HVGA, QVGA, WVGA, WQVGAThese terms refer to the screen resolution.VGA: Video Graphics Array: displays the drawing matrix, which is equivalent to 640x480 pixels;HVGA: Half-size VGA; that is, Half of VGA, resolution: 480 × 320;QVGA: Quarter VGA; that is, 1/4 of VGA, resolution: 320 × 240;WVGA: Wide V

The computer CPU has a core graphics card, and the independent graphics card is NVIDIA's geforce. When fedora 20 64-bit is installed, it generally has a priority. There is a video card startup option in the computer bios. PCIe or igfx, PCIe is an independent video card, and igfx is an integrated Intel Core display. Perform two experiments. 1. Set the BIOS display to PCIe without disabling the kernel display. If you insert the VGA of the monitor int

is mostly above 600 yuan, this aspect capital investment is indispensable. In addition, when acquiring a second monitor, you also need to pay attention to the matching upgrade of the graphics card output interface type to match with the new monitor, such as your old monitor DVI interface, but the graphics card has only a D-VI interface and an HDMI interface, then the new monitor must be able to support the HDMI interface, Otherwise you have to buy another transfer device, this will be more trou

Now the computer has become the home of the multimedia center, computers can watch movies, listen to music, play games, surf the internet and so on, now the media resources on the network is very rich, 1080p/720p HD movies are also many, but the size of the computer monitor is small, even in the 24-inch display to see the film, the effect is not very cool, And sitting in front of the monitor for a long time, also very uncomfortable. The TV screen is much larger than the display, the color is mor

In the real world, buildings were built at least in the 1980s S, and are generally not designed for the cabling requirements of the Information Age. Cabling slots and channels are generally crowded. Cables required to support high-definition videos (VGA or XGA at least) (for example, coaxial cables connected at the top of a 5 BNC connector or

do not pay much attention to the wide screen resolution supported by integrated graphics cards, so they have not updated the BIOS. What should I do if I encounter such a problem? You can use CBROM to create one by yourself. For ease of operation, I renamed them old. Bin (wide screen resolution not supported) and new. Bin (wide screen resolution supported ). The operating principle is to use CBROM (the latest version is 2.19) to extract the VGA (displ
