This book was released on 1993 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: In some cases guarding eliminates branches with a poor prediction accuracy, in other cases it eliminates branches with good predictability. However, the use of guarding results in a significant increase in the dynamic window size (instructions between mispredicted branches). Third, we present a new method of specifying guarded execution. The proposed method uses special GUARD instructions, which can be used to incorporate guarded execution into existing instruction sets. GUARD instructions realize the full power of guarded execution, without the drawbacks of existing methods of specifying guarded execution."

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Guarded execution, or simply guarding, is a powerful and promising concept, with the potential to reduce the unpredictability of the control flow caused by branches, and smoothen the flow of instructions in processor pipeline(s). Guarding also boosts the compiler's ability to expose instruction level parallelism to the processor, while requiring a modest amount of hardware support. These features make guarding attractive for inclusion in an architecture. However, the integration of guarding in an instruction set is not easy, especially when the designer needs to extend an existing instruction set. This thesis address [sic] two issues that are critical to the widespread acceptance for guarding: (i) the required instruction set support for guarded instructions, and (ii) the performance on aggressive processor configurations. This thesis proposes GUARD instructions, a new class of instructions that offer an easy and powerful way to accommodate guarded execution in an instruction set. With the modest requirement of just a few opcodes, GUARD instructions are sufficient to provide efficient support for full guarding. This thesis evaluates and compares the performance of three ways of supporting guarding: (i) using explicit guard operand fields in each instruction, (ii) using conditional move instructions, and (iii) the newly proposed GUARD instructions. The results of this evaluation show that for all configurations, GUARD instructions perform better than ordinary guarding. They also show that conditional moves can exploit a large fraction of the potential of full guarding, and that hardware mechanisms such as 2-level adaptive branch prediction and out-of-order execution diminish the performance potential of guarded execution."

Download or read book Processor Design written by Jari Nurmi and published by Springer Science & Business Media. This book was released on 2007-07-26 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is an extremely useful book that provides insight into a number of different flavors of processor architectures and their design, software tool generation, implementation, and verification. After a brief introduction to processor architectures and how processor designers have sometimes failed to deliver what was expected, the authors introduce a generic flow for embedded on-chip processor design and start to explore the vast design space of on-chip processing. The authors cover a number of different types of processor core.

Available in PDF, EPUB and Kindle. Book excerpt: Euro-Parisaninternationalconferencededicatedtothepromotionandadvan- ment of all aspects of parallel computing. The major themes can be divided into the broad categories of hardware, software, algorithms and applications for p- allel computing. The objective of Euro-Par is to provide a forum within which to promote the development of parallel computing both as an industrial te- nique and an academic discipline, extending the frontier of both the state of the art and the state of the practice. This is particularly important at a time when parallel computing is undergoing strong and sustained development and experiencing real industrial take-up. The main audience for and participants in Euro-Parareseenasresearchersinacademicdepartments,governmentlabora- ries and industrial organisations. Euro-Par’s objective is to become the primary choice of such professionals for the presentation of new results in their specic areas. Euro-Par is also interested in applications which demonstrate the e - tiveness of the main Euro-Par themes. There is now a permanent Web site for the series http://brahms. fmi. uni-passau. de/cl/europar where the history of the conference is described. Euro-Par is now sponsored by the Association of Computer Machinery and the International Federation of Information Processing. Euro-Par’99 The format of Euro-Par’99follows that of the past four conferences and consists of a number of topics eachindividually monitored by a committee of four. There were originally 23 topics for this year’s conference. The call for papers attracted 343 submissions of which 188 were accepted. Of the papers accepted, 4 were judged as distinguished, 111 as regular and 73 as short papers.

Book Synopsis The Microarchitecture of Pipelined and Superscalar Computers by : Amos R. Omondi
Download or read book The Microarchitecture of Pipelined and Superscalar Computers written by Amos R. Omondi and published by Springer Science & Business Media. This book was released on 1999-04-30 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to serve as a textbook for a second course in the im plementation (Le. microarchitecture) of computer architectures. The subject matter covered is the collection of techniques that are used to achieve the highest performance in single-processor machines; these techniques center the exploitation of low-level parallelism (temporal and spatial) in the processing of machine instructions. The target audience consists students in the final year of an undergraduate program or in the first year of a postgraduate program in computer science, computer engineering, or electrical engineering; professional computer designers will also also find the book useful as an introduction to the topics covered. Typically, the author has used the material presented here as the basis of a full-semester undergraduate course or a half-semester post graduate course, with the other half of the latter devoted to multiple-processor machines. The background assumed of the reader is a good first course in computer architecture and implementation - to the level in, say, Computer Organization and Design, by D. Patterson and H. Hennessy - and familiarity with digital-logic design. The book consists of eight chapters: The first chapter is an introduction to all of the main ideas that the following chapters cover in detail: the topics covered are the main forms of pipelining used in high-performance uniprocessors, a taxonomy of the space of pipelined processors, and performance issues. It is also intended that this chapter should be readable as a brief "stand-alone" survey.

This book was released on 1993 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "As the issue width and depth of pipelining of high performance superscalar processors increase, the importance of an effective instruction fetch mechanism becomes vital to delivering the potential performance of a wide-issue, deep pipelined microarchitecture. In this thesis a new dynamic branch predictor (Two-Level Adaptive Branch Prediction) and a new instruction fetch mechanism suitable for superscalar processors are proposed to reduce the branch execution penalty in instruction fetch. The branch predictor uses two levels of branch history information to make predictions: the history of the last k branches encountered, and the branch behavior for the last s occurrences of the specific pattern of these k branches. Its nine variations are identified according to how finely the history information is gathered. The cost- effectiveness of the variations is compared. Simulation results show that the average misprediction rate for the Two-Level Adaptive branch predictor with a reasonable implementation cost is 3% over nine programs in the SPEC89 benchmark suite, while other known schemes achieve at least 5.6% average misprediction rate. The branch predictor is integrated into an instruction fetch mechanism that is able to fetch multiple instructions each cycle and change instruction flow without incurring any pipeline bubbles. Compared with designs which use other branch predictors, the proposed design significantly reduces the branch execution penalty."
