At the end of the chapter we will look at the principles of low-power high-performance design. The stored-program concept originated from the Princeton Insti- Computer tute of Advanced Studies in the s and was first implemented in the 'Baby' organization machine which first ran in June at the University of Manchester in England.
What is a Fifty years of development have resulted in a spectacular increase in the perform- processor?
Over this period of relentless progress in the cost-effectiveness of computers, the principles of oper- ation have changed remarkably little. Most of the improvements have resulted from advances in the technology of electronics, moving from valves vacuum tubes to indi- vidual transistors, to integrated circuits ICs incorporating several bipolar transistors and then through generations of IC technology leading to today's very large scale inte- grated VLSI circuits delivering millions of field-effect transistors on a single chip.
As transistors get smaller they get cheaper, faster, and consume less power. This win-win scenario has carried the computer industry forward for the past three decades, and will continue to do so at least for the next few years.
However, not all of the progress over the past 50 years has come from advances in electronics technology. There have also been occasions when a new insight into the way that technology is employed has made a significant contribution. The instruction set, visible registers, memory management table structures and exception han dling model are all part of the architecture.
The pipeline structure, transparent cache, table-walking hardware and translation look-aside buffer are all aspects of the organization. Amongst the advances in these aspects of the design of computers, the introduction of virtual memory in the early s, of transparent cache memories, of pipelining and so on, have all been milestones in the evolution of computers. The RISC idea ranks amongst these advances, offering a significant shift in the balance of forces which determines the cost-effectiveness of computer technology.
A general-purpose processor is a finite-state automaton that executes instructions held in a memory. The state of the system is defined by the values held in the memory loca- tions together with the values held in certain registers within the processor itself see Figure 1. Each instruction defines a particular way the total state should change and it also defines which instruction should be executed next.
Abstraction in hardware design 3 The Stored- Figure 1. This Computer enables the processor itself to generate instructions which it can subsequently execute. Whenever a computer loads in a new program from disk overwriting an old program and then executes it the computer is employing this ability to change its own program.
Because of its programmability a stored-program digital computer is universal, which means that it can undertake any task that can be described by a suitable algo- rithm. Sometimes this is reflected by its configuration as a desktop machine where the user runs different programs at different times, but sometimes it is reflected by the same processor being used in a range of different applications, each with a fixed program.
Such applications are characteristically embedded into products such as mobile telephones, automotive engine-management systems, and so on. A modern microprocessor may be built from several million transistors each of which can switch a hundred million times a second. Watch a document scroll up the screen. Now consider that every one of those switching actions is, in some sense, the consequence of a deliberate design decision.
None of them is random or uncontrolled; indeed, a single error amongst those transitions is likely to cause the machine to collapse into a useless state.
How can such complex systems be designed to operate so reliably? A clue to the answer may be found in the question itself. We have described the oper- ation of the computer in terms of transistors, but what is a transistor?
It is a curious structure composed from carefully chosen chemical substances with complex electri- cal properties that can only be understood by reference to the theory of quantum mechanics, where strange subatomic particles sometimes behave like waves and can only be described in terms of probabilities.
Yet the gross behaviour of a transistor can be described, without reference to quantum mechanics, as a set of equations that relate the voltages on its terminals to the current that flows though it.
These equations abstract the essential behaviour of the device from its underlying physics. The equations that describe the behaviour of a transistor are still fairly complex. Figure 1. Abstraction in hardware design 5 With a bit of care we can define what is meant by 'near to' in these rules, and then associate the meaning true with a value near to Vdd and false with a value near to Vss. The con- cepts that the logic designer works with are illustrated in Figure 1.
Truth table The gate This is a symbol that represents a NAND gate function in a circuit schematic; abstraction there are similar symbols for other logic gates for instance, removing the bubble from the output leaves an AND gate which generates the opposite output func- tion; further examples are given in 'Appendix: Computer Logic' on page This describes the logic function of the gate, and encompasses everything that the logic designer needs to know about the gate for most purposes.
The significance here is that it is a lot simpler than four sets of transistor equations. In this truth table we have represented 'true' by '1' and 'false' by '0', as is common practice when dealing with Boolean variables. The point about the gate abstraction is that not only does it greatly simplify the process of designing circuits with great numbers of transistors, but it actually Figure 1. A logic circuit abstraction should have the same logical behaviour whether the gates are implemented using field-effect transistors the transistors that are available on a CMOS process , bipo- Gate-level lar transistors, electrical relays, fluid logic or any other form of logic.
The imple- design mentation technology will affect the performance of the circuit, but it should have no effect on its function. It is the duty of the transistor-level circuit designer to sup- port the gate abstraction as near perfectly as is possible in order to isolate the logic circuit designer from the need to understand the transistor equations. It may appear that this point is being somewhat laboured, particularly to those read- ers who have worked with logic gates for many years.
However, the principle that is illustrated in the gate level abstraction is repeated many times at different levels in computer science and is absolutely fundamental to the process which we began con- sidering at the start of this section, which is the management of complexity.

Not loaded yet?Preface Arm system on chip architecture pdf free download This book introduces the concepts and methodologies employed in designing a system-on-chip SoC based around a microprocessor core and in designing the Audience microprocessor core itself. The principles of microprocessor design are made con- crete by extensive illustrations based upon the ARM. Prerequisite knowledge The aim of the book is to assist the reader in understanding how SoCs autodesk maya 2013 64 bit crack free download micro- processors are designed and used, and why a modern processor is designed the way The ARM that it is. The reader who wishes to know only the general principles should find that the ARM illustrations add substance to issues which can otherwise appear somewhat ethereal; the reader who wishes to understand the design of the ARM should find that the general principles illuminate the rationale for the ARM being as it is. Other microprocessor architectures are not described in this book. The reader who wishes to make a comparative study of architectures will find the required informa- tion on the ARM here but must look elsewhere for information on other designs. Although there is considerable overlap with ARM technical publications, this book provides a broader context with more background. It is not a substitute for the manufac turer's data, since much detail has had to be omitted, but arm system on chip architecture pdf free download should be useful as an introductory overview and adjunct to that data. Some chapters are closely based on arm system on chip architecture pdf free download material previously used in undergraduate teaching; some other material is drawn from a postgraduate course. This book is not intended to be an introductory text on computer architecture or 14000 objective questions general studies pdf free download logic design. Readers are assumed to have a level of familiarity with these subjects equivalent to that of a second year undergraduate student in computer sci- ence 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 arm system on chip architecture pdf free download with the ARM processor is assumed. For the remainder of the s the ARM was quietly developed to underpin Acorn's desktop products which form the basis of educational computing in the UK; over the s, in the care arm system on chip architecture pdf free download 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 system on chip architecture pdf free download developments appear. Most of the principles of modern SoC and processor design are illustrated some- where in the ARM family, and ARM has led the way in the introduction of some con- cepts such as dynamically decompressing the instruction stream. The inherent simplicity of the basic 3-stage pipeline ARM core makes it a good pedagogical intro- ductory 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. Book Structure Chapter 1 starts with a refresher on first year undergraduate processor design mate- rial. It illustrates the principle of abstraction in hardware design by reviewing the roles of logic and gate-level representations. It then introduces the important con- cept of the Reduced Instruction Set Computer RISC as background for arm system on chip architecture pdf free download fol- lows, and closes with some comments on design for low power. Chapter 2 describes the ARM processor architecture in terms of the concepts intro- duced in the previous chapter, and Chapter 3 is a gentle introduction arm system on chip architecture pdf free download user-level assembly language programming and could be used in first year undergraduate teach- ing for this purpose. Chapter 4 describes the organization and implementation of the 3- and 5-stage pipeline ARM processor cores at a level suitable for second year undergraduate teach- ing, and covers some implementation issues. Chapters 5 and 6 go into the ARM instruction set architecture in increasing depth. Chapter 5 goes back over the instruction set in more detail than was presented in Chapter 3, including the binary representation of each instruction, and it penetrates arm system on chip architecture pdf free download deeply into the comers of the instruction set. It is probably best read once and then used for reference. Pages·· MB·1, Downloads·New! challenging problem of getting a complex SoC design right first time. ARM System-on-Chip Archit.
