Product data sheet
1. Introduction
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.
1.1 Features
The major features of the 2D drawing engine are:
⢠High Speed Operation
⢠3 operand bit BLT (256 Raster operations)
⢠Alpha Blending
⢠Transparent bit BLT
⢠Fast host monochrome to full color expansion for text, mono bitmaps, and
patterns
⢠Lines
2. Functional Description
A block diagram of the 2D drawing engine is shown in Figure 1.
