The ARM processor core is a key component of many successful 32-bit embedded systems. You probably own one yourself and may not even realize it! ARM cores are widely used in mobile phones, handheld organizers, and a multitude of other everyday portable consumer devices. ARM’s designers have come a long way from the first ARM1 prototype in 1985. Over one billion ARM processors had been shipped worldwide by the end of 2001. The ARM company bases their success on a simple and powerful original design, which continues to improve today through constant technical innovation. In fact, the ARM core is not a single core, but a whole family of designs sharing similar design principles and a common instruction set. For example, one of ARM’s most successful cores is the ARM7TDMI. It provides up to 120 Dhrystone MIPS1 and is known for its high code density and low power consumption, making it ideal for mobile embedded devices. In this first chapter we discuss how the RISC (reduced instruction set computer) design philosophy was adapted by ARM to create a flexible embedded processor. We then introduce an example embedded device and discuss the typical hardware and software technologies that surround an ARM processor.

2007年五星书 英文版 Digital Design (Verilog): An Embedded Systems Approach Using Verilog Product Description Digital Design: An Embedded Systems Approach Using Verilog provides a foundation in digital design for students in computer engineering, electrical engineering and computer science courses. It takes an up-to-date and modern approach of presenting digital logic design as an activity in a larger systems design context. Rather than focus on aspects of digital design that have little relevance in a realistic design context, this book concentrates on modern and evolving knowledge and design skills. Hardware description language (HDL)-based design and verification is emphasized--Verilog examples are used extensively throughout. By treating digital logic as part of embedded systems design, this book provides an understanding of the hardware needed in the analysis and design of systems comprising both hardware and software components. Includes a Web site with links to vendor tools, labs and tutorials. Presents digital logic design as an activity in a larger systems design context. Features extensive use of Verilog examples to demonstrate HDL usage at the abstract behavioural level and register transfer level, as well as for low-level verification and verification environments. Includes worked examples throughout to enhance the reader's understanding and retention of the material. Companion Web site includes links to CAD tools for FPGA design from Synplicity, Mentor Graphics, and Xilinx, Verilog source code for all the examples in the book, lecture slides, laboratory projects, and solutions to exercises.
