This Manual contains information on the Am29000 processor which is essential for computer hardware and software architects and system design engineers. Additional information is available in the form of Data Sheets, Application Notes, and other documentation which is provided with software products and hardware-development tools. The information in this manual is organized into eight chapters, each viewing the processor from a different perspective, and each with a specific objective: Chapter 1 introduces the features and performance aspects of the Am29000. Chapter 2 contains brief technical descriptions of the processor architecture and implementation. Chapter 3 describes the details of the Am29000 architecture. Chapter 4 details the operation of the processor's internal functional units. Chapter 5 describes the operation of the external interfaces of the Am29000. Chapter 6 describes the attachment and use of coprocessors for the Am29000 Chapter 7 discusses the implementation of software systems for the processor, focusing on programming features which deserve more coverage than is provided by other chapters. Chapter 8 specifies the instruction set of the Am29000. It describes the instruction formats in detail, and provides a detailed description of every instruction. This Manual is organized around readers' concerns and objectives. Each chapter focuses on a particular aspect of the processor, and is organized so that it may be read independently, insofar as possible.
