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

effect is unacceptable and is not recommended.Iv. Connection Method VGA Note: "home theater. LCD TV. common interfaces (1)" describes VGA interfaces. Method:The audio interface is on the right of the VGA interface.Select PC as the TV Signal SourceEffect:The display is completely normal, with slight audio noisesSummary:When Samsung and many other brand LCD TVs ar

1. Differences between drawable-(hdpi, mdpi, ldpi)DPI is the abbreviation of "dot Per Inch". The number of dots per inch.Four density classifications: ldpi (low), mdpi (medium), hdpi (high), and xhdpi (extra high)Normal screen: ldpi is 120, mdpi is 160, hdpi is 240, and xhdpi is 320. 2. Differences between WVGA, hvga, and qvgaVGA is the "video graphics array", and the display standard is 640*480.WVGA (wide VGA) Resolution is 480*800Hvga (half
