Design and Implementation of Analog Display on an Embedded Platform

An analog display module, which is used on an embedded platform based on Intel Xscale processor and Microsoft WinCE OS, is discussed. The display module uses CH7005 as its TV encoder and outputs NTSC TV signal. The hardware framework and design of the analog display module is presented, as well as software solutions and the measures to optimize its performances. The test results show that the Signal-to-Noise Ratio (SNR) of this analog display module is up to the national standard.
