1. Introduction
2. Functional Description
1.1 Features
The purpose of this module is to accelerate the 2D drawing operations that are most
heavily used in a graphics environment. The 2D drawing engine (2DDE or DE in the
following text or data book) interfaces with both the internal MMIO-DTL bus and the
internal memory bus. DE operation may be synchronous to the memory interface,
with a small portion of the module operating at the MMIO bus clock frequency.
The major features of the 2D drawing engine are:
