AMD Alchemy Solutions Au1100 Processor LCD Performance
Rev. 30274A April 2003
1.0 Introduction
This document describes the performance characteristics of an Au1100 processor based design
using the integrated LCD controller.
This document assumes the reader is familiar with LCD technology and the
AMD Alchemy
Solutions Au1100 Processor Data Book
(see 7.0 “References”).
This document also assumes the reader is familiar with the applications note “Au1x00 SDRAM
Performance” which outlines SDRAM performance for a typical system (see 7.0 “References”). The
remainder of this document uses numbers for a 396MHz system with a 99MHz SDRAM interface, as
outlined in the SDRAM applications note.
2.0 LCD Controller Overview
The Au1100 processor features an integrated LCD controller for connecting to liquid crystal displays
and cathode ray tubes. The LCD controller supports the common industry standard TFT and STN
panel technologies and is able to drive cathode ray tubes via an external digital-to-analog converter
(DAC). In the discussion to follow, the term display is a reference to either a TFT or a cathode ray
tube with an appropriate DAC. The majority of the information presented in this document is
applicable for an STN panel, but the calculations differ.
The Au1100 processor databook contains details and additional information on the operation of the
LCD controller. The general arrangement of the Au1100 processor LCD controller is depicted below.
