The Amiga Technical Reference Series is the official guide to programming Amiga computers. This revised edition of the Amiga Hardware Reference Manual provides detailed information about the Amiga's graphics and audio hardware, and how the Amiga talks to the outside world through peripheral devices. This edition has been updated for version 2.0 of the Amiga operating system and covers the newest Amiga computer systems including the A3000. This book is intended for the following audiences: * Assembly language programmers who need a more direct way of interacting with the Amiga than the routines provided in the system software. * Designers who want to interface new peripherals to the Amiga. * Anyone who wants to know how the Amiga hardware works. Here is a brief overview of the contents: Chapter 1, Introduction . An overview of the hardware and survey of the Amiga's graphics and audio features. Chapter 2, Coprocessor Hardware . Using the Copper coprocessor to control the entire graphics and audio system; directing mid-screen modifications in graphics displays and directing register changes during the time between displays. Chapter 3, Playfield Hardware . Creating, displaying and scrolling the playfields, one of the basic display elements of the Amiga; how the Amiga produces multi-color, bitmapped displays. Chapter 4, Sprite Hardware . Using the eight sprite direct memory access (DMA) channels to make sprite movable objects; creating their data structures, displaying and moving them, reusing the DMA channels. Chapter 5, Audio Hardware . Overview of sampled sound; how to produce quality sound, simple and complex sounds, and modulated sounds. Chapter 6, Blitter Hardware . Using the blitter DMA channel to create animation effects and draw lines into playfields. Chapter 7, System Control Hardware . Using the control registers to define depth arrangement of graphics objects, detect collisions between graphics objects, control direct memory access, and control interrupts. Chapter 8, Interface Hardware . How the Amiga talks to the outside world through controller ports, keyboard, audio jacks and video connectors, serial and parallel interfaces; information about the disk controller and RAM expansion slot. Appendices. Alphabetical and address-order listings of all the graphics and audio system registers and the functions of their bits. Also included is a special section on the Amiga's Enhanced Chip Set (ECS), system memory maps, descriptions of internal and external connectors, specifications for the peripheral interface ports, keyboard, and an introduction to the Amiga's Zorro expansion bus with detailed specifications for hardware add-on designers. We suggest that you use this book according to your level of familiarity with the Amiga system. Here are some suggestions: * If this is your initial exposure to the Amiga, read chapter 1, which gives a survey of all the hardware features and a brief rundown of graphics and audio effects created by hardware interaction. * If you are already familiar with the system and want to acquaint yourself with how the various bits in the hardware registers govern the way the system functions, browse through chapters 2 through 8. Examples are included in these chapters. * For advanced users, the appendices give a concise summary of the entire register set and the uses of the individual bits. Once you are familiar with the effects of changes in the various bits, you may wish to refer more often to the appendices than to the explanatory chapters. The other manuals in this series are the Amiga User Interface Style Guide, an application design specification and reference work for Amiga programmers, the Amiga ROM Kernel Reference Manual: Includes and Autodocs, an alphabetically organized reference of ROM function summaries and Amiga system include files, the Amiga ROM Kernel Reference Manual: Libraries and the Amiga ROM Kernel Reference Manual: Devices with tutorial-style chapters on the use of each Amiga system library and device.
