Abstract

Disclosed is a device and a method for antialiasing high resolution pixel data into low resolution pixel data for display at the low resolution. Figure 2 shows a detailed block diagram of the graphics subsystem (112) in accordance with one embodiment of the present invention. The graphics subsystem (112) includes: a graphics processor (202), which generates HSYNC1, VSYNC1, PCLK1 Pixel Data, a frame buffer (204) that transmits pixel data values, to the graphics processor (202) and an antialiasing unit (206), coupled to the graphics processor (202). The antialiasing unit (206) transmits HSYNC2 and VSYNC2 to the display device. The DAC (208) receives pixel data PCLK2 from the antialiasing unit (206) and transmits RGB to the video amplifier (210), which is optinal and may be provided externally. The video amplifier drives the RGB to the display device.
