OTHER FUNCTION BLOCKS
2.8.1
ATTRIBUTE CONTROLLER
The Attribute Controller formats the display for the screen.
Display color selection, text
blinking, alternate font selection, and underlining are performed by the Attribute Controller.
2.8.2
CRT CONTROLLER
The CRT Controller generates the HSYNC and VSYNC signals required for the monitor, as
well as BLANK signals required by the Attribute Controller.
2.8.3
CRT FIFO
The CRT FIFO allows the Display Memory Controller to access the display memory for
screen refresh at maximum memory speed rather than at the screen refresh rate. It provides
3 programmable thresholds - CRT/CPU Threshold Low, CRT/CPU Threshold High, and
CRT/Engine Threshold High. With adequate setting these three thresholds, the CPU wait-
time would be reduced to improve the graphics performance.
2.8.4
DDC CONTROLLER
The DDC Controller provides two different channels to communicate with the monitor which
supports DDC level 1 or DDC level 2B. One is DDC CLK channel which is bi-directional and
provides the clock for DDC. The other is DDC DATA channel which is bi-directional and can
query some information from monitor.
With the advantage of DDC, VGA BIOS can realize the capability of the connected monitor
and take adequate action (such as to program the parameters for higher frame rate, ..., etc.)
to make end users feel more comfortable.
2.8.5
DPMS
It provides some registers to control the CRT timing to be compatible with the VESA DPMS
specification.
2.8.6
GRAPHICS CONTROLLER
It performs text manipulation, data rotation, color mapping, and miscellaneous operations.
2.8.7
GRAPHICS & VIDEO RAMDAC
The RAMDAC contains the color palette and 24-bit true color DAC.
The maximum
frequency of the RGB DAC is 270 MHz. It can support 1920x1200 video mode.
The color palette, with 256 18-bit entries, converts a color code that specifies the color of a
pixel into three 6-bit values, one each for red, green, and blue.
The 24-bit true color DAC is designed for direct color graphics mode. It converts each digital
