6.3. Architecture

This chapter describes the Driver Architecture and Design concepts

6.3.1. Driver Architecture

OMAP35x display hardware integrates one graphics pipeline, two video
pipelines, and two overlay managers (one for digital and one for analog
interface). Digital interface is used for LCD and DVI output and analog interface
is used for TV out.
The primary functionality of the display driver is to provide interfaces to
user level applications and management to OMAP35x display hardware. This
includes, but is not limited to:
•
•
•
