Instruction-level pipelining is introduced as well. Real-world ISAs (including Intel, MIPS, and Java) are discussed to reinforce the concepts presented in the chapter. This chapter should be covered after Chapter 4. Lectures should focus on the following points: Instruction formats. Important issues here include instruction length, little versus big endian, register usage (and the use of stacks), and expanding opcodes. Addressing. Although addressing is an instruction design issue, there are many aspects to consider, the most important of which is addressing modes. Instruction-level pipelining. The fetch-decode-execute cycle can be overlapped, resulting in faster execution time. Resource conflicts, conditional branching, and data dependencies can slow this process down. Real-world examples of ISAs. Intel, MIPS, and the Java virtual machine are all presented to reinforce the concepts of the chapter. Required Lecture Time The important concepts in Chapter 5 can typically be covered in 3 lecture hours. However, if a teacher wants the students to have a mastery of all topics in Chapter 5, 8 lecture hours are more reasonable. If lecture time is limited, we suggest that the focus be on instruction formats (including big versus little endian, use of registers, and instruction length) and addressing (with considerable attention paid to the various modes). Page 1 Many students comprehend the concept, but don't see the significance. The various software applications listed in this chapter will help the instructor make this point. Students often have difficulty understanding stack machines. It is important to emphasize that not ALL instructions on stack machine have zero operands, but rather, the instructions that allow for operands are limited. The concept of expanding opcodes is sometimes difficult for students as well. We suggest going over a small example in detail.

When covering the addressing modes, we suggest that instructors include many examples, as this is one concept that tends to be easier to understand through examples. Students often confuse instruction-level pipelining with other types of pipelining. It is important to stress that there are many types of pipelining, but in this chapter only pipelining the fetch-decode-execute cycle is addressed. Although the real-life examples can be left for students to read, these case studies provide the instructor with a means to tie the concepts from this chapter together, as well as a method for motivating study of the concepts from this chapter. Answers to Exercises 1. Assume you have a machine that uses 32-bit integers and you are storing the hex value 1234 at address 0. a. Show how this is stored on a big endian machine. b. Show how this is stored on a little endian machine. c. If you wanted to increase the hex value to, which byte assignment would be more efficient, big or little endian. Explain your answer. a and b. Address Big Endian Little Endian c. Little endian is more efficient because the additional information simply needs to be appended. Assume each value starts at address Draw a diagram of memory for each, placing the appropriate values in the correct (and labeled) memory locations. Page 2. For example, the value from Problem 3, sent as the value -511 on a big endian machine, would be read as the value 510 on a little endian machine. 5. The Population Studies Institute monitors the population of the United States. In 2000, this institute wrote a program to create files of the numbers representing the various states, as well as the total population of the U.S. This program, which runs on a Motorola Page 3 The Institute runs the program and then ships the output files to state agencies so the data values can be used as input into various applications.

However, one Pennsylvania agency, running all Intel machines, encountered difficulties, as indicated by the following problem. When the 32-bit unsigned integer 1D2F37E8 16 (representing the overall U.S. population predication for 2003) is used as input, and the agency's program simply outputs this input value, the U.S. population forecast for 2003 is far too large. Can you help this Pennsylvania agency by explaining what might be going wrong. Hint: They are run on different processors. Intel and Motorola use different endian-ness. If the program on the Intel machine does not adjust for this, then the integer is interpreted incorrectly. 6. There are reasons for machine designers to want all instructions to be the same length. Why is this not a good idea on a stack machine. The only instructions on a stack machine that need to address memory are push and pop. So an operand field is required, which implies the instruction field must be divided into an opcode and an operand. However, the other instructions need not access memory and can thus consist of only the opcode. Suppose there are address instructions. How many 1-address instructions can be formulated. Explain your answer. There are address instructions. There are only a total of address instructions allowed if we have 32-bit instructions (two addresses take up 24 bits, leaving only 8 bits for the opcode). Looking at the 8 bit opcode, assume bit patterns (0) through (249) are used for the 250 two-address instructions. Then there are 6 bit patterns left for one address instructions. Remember the rules of precedence for arithmetic operators. Is it possible to have: 5 2-address instructions 45 1-address instructions Page 5 Justify your answer. b. Assume that a computer architect has already designed 6 two-address and 24 zeroaddress instructions using the instruction format above. What is the maximum number of one-address instructions that can be added to the instruction set? a. Yes.
The 2-address instructions could be represented 000xxxxxxxx through 100xxxxxxxx (using 000 through 100 for opcodes). The 1-address instructions could use through (16), through (16), and through (13 more, for a total of 45). The 0-address instructions could use through (16), and through (16). So we have: 000 xxxx xxxx 100 xxxx xxxx xxxx xxxx xxxx xxxx xxxx xxxx address instructions address instructions address instructions 16 b. Assume the two-address instructions use bit patterns 000 xxxx xxxx through 101 xxxx xxxx. Assume also that the zero-address instructions are of the format through (8), through (8), and through (8) (These constitute the last 16 binary numbers possible with 11 bits). Then all instructions beginning with 110 ( xxxx through xxxx) could be one address instructions (16). In addition, xxxx through xxxx could be one address instructions, giving us 14 more, for a total of address instructions. 12. What is the difference between using direct and indirect addressing. Give an example. Direct addressing provides the actual memory address of the operand in the instruction, whereas indirect addressing provides, as part of the instruction, a pointer to a memory location. For example, the instruction Load X interpreted using direct addressing would go to memory location X and load the value found there. Using indirect addressing, memory location X would be used as the effective address of what should actually be loaded. So if a value of 200 were found at location X, the value located at address 200 would be loaded. Page 6 Given memory and register R1 contain the values below: R1 200 Assuming R1 is implied in the indexed addressing mode, determine the actual value loaded into the accumulator and fill in the table below: Page 7 A nonpipelined system takes 200ns to process a task. The same task can be processed in a 5-segment pipeline with a clock cycle of 40ns. Determine the speedup ratio of the pipeline for 200 tasks.

What is the maximum speedup that could be achieved with the pipeline unit over the nonpipelined unit. The same task can be processed in a 5-segment pipeline with a clock cycle of 20ns. Determine the speedup ratio of the pipeline for 100 tasks. What is the theoretical speedup that could be achieved with the pipeline system over a nonpipelined system. In accordance with programming language practice, computing the expression should not change the values of its operands.

A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an Page 8 The computer has an instruction format with 4 fields: an opcode field; a mode field to specify 1 of 7 addressing modes; a register address field to specify one of 60 registers; and a memory address field. Assume an instruction is 32 bits long. Suppose an instruction takes four cycles to execute in a nonpipelined CPU: one cycle to fetch the instruction, one cycle to decode the instruction, one cycle to perform the ALU operation, and one cycle to store the result. In a CPU with a 4-stage pipeline, that instruction still takes four cycles to execute, so how can we say the pipeline speeds up the execution of the program. For one instruction, there is no speedup. The speedup comes with the parallel execution of multiple instructions. While the first instruction is decoding, the second can be fetched; while the first instruction is performing the ALU instruction, the second can be decoding, and the third can be fetched, etc. 21.

The same task can be processed in a 5-segment pipeline with a clock cycle of 60ns. The instruction set consists of 128 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address).Computer Systems Design and Architecture 2.1, 2.2, 3.2 These computers are designed and constructed based on digital and Integrated Circuit Dr. HASAN HUSEYIN BALIK DECEMBER The concept of addressing data' in computations.

Press to instructors who adopt the textbook.As a prominent example of the class of reduced instruction-set architectures (RISC), MIPS has been found quite suitable for use in various educational settings. References to simplified RISC instruction sets under the designations MiniMIPS and MicroMIPS, introduced in Chapters 5 and 13, respectively, have no relations with specific architectures offered by MIPS Technologies, Inc. These simplifications form proper subsets of the well-documented MIPS instruction set and have not been otherwise modified. Reference is also made to SPIM, a software simulator for the MIPS instruction set, which is provided free of charge to everyone, courtesy of Dr. James R. Larus.This explains, in part, why there are so many different textbooks on computer architecture and why yet another textbook on the subject might serve a useful purpose.It also branches into more advanced subfields, each with its own community of researchers, periodicals, symposia, and, of course, technical jargon. Computer designers must no doubt be familiar with the entire field to be able to use the range of available methods in designing fast, efficient, and robust systems. Less obvious is the fact that even simple computer users can benefit from a firm grasp of the core ideas and from an awareness of the more advanced concepts in computer architecture.Much of this complexity arises from our desire to make everything as fast as possible.
Some of the resulting techniques, such as predictive and speculative execution, are at odds with other goals of system design that include low cost, compactness, power economy, short time to market, and testability. It is the constant push and pull of such conflicting requirements that makes computer architecture a thriving and exciting field of study. Adding to the excitement are the opposing forces of innovation and compatibility with existing investments in skills, systems, and applicationsEach lecture, lasting one to two hours, has a theme or title and proceeds from motivation to details to conclusion. These are well-thought-out problems, many of them class-tested, that clarify the chapter material, offer new viewing angles, link the chapter material to topics in other chapters, or introduce more advanced concepts. Such designs also provide building blocks for synthesis and reference points for cost-performance comparisons. Such links, from the obvious (instruction-set architecture vis-a-vis compiler design) to the subtle (interplay of architecture with reliability and security), are explained throughout the book. Examples of material not found in many other texts include detailed coverage of computer arithmetic (Chapters 9-12) and high-performance computing (Chapters 25-28). For example, r always stands for the number representation radix, k for word width, and c, for carry. Similarly, concepts and structures are consistently identified with unique, well-defined names.Included are two refresher-type chapters on digital circuits and components, a discussion of computer system types, an overview of digital computer technology, and a detailed perspective on computer system performance.For concreteness, the instruction set of MiniMIPS (a simplified, yet very realistic, machine for which open reference material and simulation tools exist) is described. Included is a chapter on variations in ISA (e.g., RISC vs CISC) and associated cost-performance trade-offs.
Implementation aspects and pitfalls of floating-point arithmetic are also discussed.Beginning with stages of instruction execution, the needed components and control mechanisms are derived. This material is followed by an exposition of control design strategies, use of a pipelined data path for performance enhancement, and various limitations of pipelining due to data and control dependencies.The technologies in use for primary and secondary memories are described, along with their strengths and limitations. It is shown how the use of cache memories effectively bridges the speed gap between CPU and main memory. Similarly, the use of virtual memory to provide the illusion of a vast main memory is explained. Elements of processes and context switching, for exception handling or multithreaded computation, are also covered.An overview of performance enhancement strategies, beyond simple pipelining, is presented, and examples of applications requiring higher performance are cited. The book concludes with design strategies and example architectures based on vector or array processing, multiprocessing, and multicomputing.In his own teaching, the author has used the chapters primarily for 1.5-hour lectures, twice a week, in a 10-week quarter, omitting or combining some chapters to fit the material into the 18-20 lectures that are available. But the modular structure of the text lends itself to other lecture formats, self-study, or review of the field by practitioners. In the latter two cases, the readers can view each chapter as a study unit (for one week, say) rather than as a lecture. Ideally, all topics in each chapter should be covered before moving to the next chapter. However, if fewer lecture hours are available, then some of the subsections located at the end of chapters can be omitted or introduced only in terms of motivations and key results.
