Unformatted text preview: eaders are assumed to have a level of familiarity with these subjects equivalent to that of a second year undergraduate student in computer science or computer engineering. Some first year material is presented, but this is more by way of a refresher than as a first introduction to this material. No prior familiarity with the ARM processor is assumed. On 26 April 1985, the first ARM prototypes arrived at Acorn Computers Limited in Cambridge, England, having been fabricated by VLSI Technology, Inc., in San Jose, Audience The ARM iv Preface California. A few hours later they were running code, and a bottle of Moet & Chan-don was opened in celebration. For the remainder of the 1980s the ARM was quietly developed to underpin Acorn's desktop products which form the basis of educational computing in the UK; over the 1990s, in the care of ARM Limited, the ARM has sprung onto the world stage and has established a market-leading position in high-performance low-power and low-cost embedded applications. This prominent market position has increased ARM's resources and accelerated the rate at which new ARM-based developments appear. The highlights of the last decade of ARM development include: the introduction of the novel compressed instruction format called 'Thumb' which reduces cost and power dissipation in small systems; significant steps upwards in performance with the ARM9, ARM 10 and 'StrongARM' processor families; a state-of-the-art software development and debugging environment; a very wide range of embedded applications based around ARM processor cores. Most of the principles of modern SoC and processor design are illustrated somewhere in the ARM family, and ARM has led the way in the introduction of some concepts (such as dynamically decompressing the instruction stream). The inherent simplicity of the basic 3-stage pipeline ARM core makes it a good pedagogical introductory example to real processor design, whereas the debugging of a system based around an ARM core deeply embedded into a complex system chip represents the cutting-edge of technological development today.
