ARM9TDMI Processor Core

Introduction

1.1 About the ARM9TDMI

The ARM9TDMI is a member of the ARM family of general-purpose microprocessors.

The ARM9TDMI is targeted at embedded control applications where high

performance, low die size and low power are all important. The ARM9TDMI supports

both the 32-bit ARM and 16-bit Thumb instruction sets, allowing the user to trade off

between high performance and high code density. The ARM9TDMI supports the ARM

debug architecture and includes logic to assist in both hardware and software debug.

The ARM9TDMI supports both bidirectional and unidirectional connection to external

memory systems. The ARM9TDMI also includes support for coprocessors.

The ARM9TDMI processor core is implemented using a five-stage pipeline consisting

of fetch, decode, execute, memory and write stages. The device has a Harvard

architecture, and the simple bus interface eases connection to either a cached or

SRAM-based memory system. A simple handshake protocol is provided for

coprocessor support.
