- INTRODUCTION
-
- Thank you for your interest in obtaining programming documentation for
- ATI products based on the ATI Mach32 graphics accelerator chipset.
- Products using this chipset include the Graphics Ultra Pro, Graphics
- Ultra + and various products that ATI manufactures for computer
- vendors. This document describes the Mach32 Programmer's Kit, its
- purpose and how to obtain the kit. It also describes what materials
- are NOT available and the terms and conditions by which we are
- offering the kit.
-
- ATI has not publicly announced the availability of the Mach32
- Programmer's Kit because the material are not complete at this time.
- However, what we are offering today may be sufficient to meet some
- programmers' requirements. Please read this document carefully before
- placing an order.
-
- AVAILABLE MATERIALS
-
- 1) Programmer's Guide to the Mach32 Registers
-
- A 350 page register specification detailing all 252
- registers including all VGA, 8514/a and ATI Mach-8
- compatible registers. Subjects include the Bresenham vector
- & polygon drawing engine, the Direct Draw drawing engine,
- the BitBLT engine, the hardware cursor, the pixel transfer
- ALU and CRT controller.
-
- The register specification is a reference for programmers
- with experience writing device drivers for graphics co-
- processors at the register level.
-
-
-
-
- 2) Programmer's Guide to the Mach32 Adapter Interface
-
- The Turbo AI is a high level interface compatible with the
- IBM Adapter Interface Specification. It is implemented as a
- TSR which provides a set of callable high level functions
- for mode selection and initialization, primitive drawing
- functions, color palette manipulation, font handling and
- other useful functions. Modes supported are 640X480 and
- 1024X768 /256 colors only. Other resolutions and color
- depths supported by the hardware are outside the AI
- Specification.
-
- ATI recommends the AI to those programmers who would like to
- take advantage of hardware assisted drawing capability
- without a heavy investment in development time or if
- register level device driver expertise is not available.
-
- 3) Mach32 Application Notes
-
- AN0001 - Accessing Video RAM via the Linear or Banked Memory
- Aperture
-
- This discusses techniques for accessing the video RAM,
- the Linear Aperture and the VGA Aperture. The Linear
- Aperture make use of a relocatable Extended memory
- address. It offers true 32 bit linear addressing for
- enhanced performance for protected mode software. The
- VGA aperture allows the video memory to be addressed
- like a SuperVGA card. It provides access to up to 2M of
- RAM via banking for real mode software.
-
- AN0002 - Setting screen modes using the Adapter ROM
-
- This discusses the use of internal ROM routines to set
- up and initialize all supported resolution/color modes.
-
-
- AN0003 - Detection of a Mach32 adapter
-
- This covers identification of Mach32 products via a
- combination of the ATI ROM signature and register
- read/writes.
-
- AN0006 - Drawing Solid or Patterned Lines with Hardware
-
- - This discusses the use of the ATI Direct Draw Engine
- for high speed vector drawing.
-
- 4) VESA Interface Disk
-
- A 3.5" HD diskette containing a TSR which supports the VESA
- SuperVGA BIOS Extension standard on Mach32 products.
- Resolutions supported up to 1024X768 in 16, 256 and 32K
- colors. A utility which can display the supported video mode
- is supplied along with an demonstration program which uses

- WHAT IS NOT AVAILABLE
-
- ATI intends to offer additional application notes on polygon
- drawing, BitBLT engine operation, hardware cursor and text
- generation. A set of sample code segments in MS C and MASM is
- also planned. These items are planned for release by the end of
- first quarter, 1993.
-
- ATI does NOT plan to offer a linkable graphics function library
- or high level interface for our products. However, ATI encourages
- and assists developers of commercial graphics library packages to
- support our products. None of these graphics library vendors have
- yet announced a version which supports the Mach32. If you are a
- current user of a graphics library, please contact the
- manufacturer for information about if and when they plan to
- release a version which supports ATI Mach32 products.
-
- PLEASE READ BEFORE ORDERING
-
- The Mach32 is a uniquely flexible device which is compatible with IBM
- VGA, 8515/a and earlier ATI SuperVGA and Accelerator products. It is
- entirely possible to implement software which uses the Mach32 as a
- SuperVGA, as a linear frame buffer or as an accelerator card.
-
- Application notes 1, 2 & 3 contain sufficient information for the
- experienced programmer to use all high resolution and/or high color
- modes of the Mach32 as a SuperVGA or linear frame buffer card. If you
- are not familiar with Super-VGA programming techniques, ATI offers the
- VGAWONDER Programmer's Reference Manual.
-
- The Mach32 also contains a high performance graphics engine. This
- provides hardware assist for vector/polygon drawing, screen to screen
- BitBLT, hardware cursor and several other functions. Programming the
- graphics engine is much different and more difficult than any
- conventional frame buffer card (EGA, VGA..etc). Only programmers with
- experience designing graphics primitive functions and writing device
- drivers for programmable peripheral devices on the PC should attempt
- to access the engine directly. We would recommend that unless you
- already have experience with other accelerator cards, such as 8514/a
- or XGA, or have source code examples for such cards that you delay
- ordering until our example code is released. Otherwise, ATI recommends
- using the Adapter Interface or obtaining a graphics library from a
- third party vendor.
-
- All examples are written in MS C and MS MASM. Familiarity with the
- syntax and conventions of these compilers is required. ATI does not
- support other compilers and will not assist with conversion of sample
- code to other compilers.
-
- ATI Customer Support will assist with installation, configuration and
- basic information but will not be able to answer specific programming
- questions.
