The architecture and structures used by the MacPitts silicon compiler to design integrated circuits are described, and the capabilities and limitations of the compiler are discussed. The performance of several combinational and pipeline adders designed by MacPitts and a hand-crafted pipeline adder are compared. Several different MacPitts design errors are documented. Tutorial material is presented to aid in using the MacPitts interpreter and to illustrate timing analysis of MacPitts-designed circuits using the program Crystal. Keywords include: VLSI Design; MacPitts silicon compiler; Pipeline adder; Block carry look ahead addition; Data-Path; and Weinberger Array.

The ILLIAC FORTRAN Compiler may be characterized as a series of transformations on the source input stream. FORTRAN code is transformed into a representation which exploits ILLIAC parallelism. This transformation is accomplished by detecting individual statements within DO loops which may be executed in parallel for values of the DO indices, and determining an ordering which preserves data dependencies. While the result of this effort affords ILLIAC parallelism, it is insensitive to two major characteristics of ILLIAC hardware: an enormous disk latency, and an ability to overlap execution of sequential and parallel components of the hardware. In order to fully exploit the capabilities of the ILLIAC, two more transformations are effected. First, code is restructured to minimize the effect of disk latency. Second, operations are allocated to maximize CU-PE overlap. At this stage it is appropriate to generate ILLIAC code.

The logic modules and data structures composing the Meta-translator module are desribed. This module is responsible for the actual generation of the executable language compiler as a function of the input Meta-language. Machine definitions are also processed and are placed as encoded data on the compiler library data file. The transformation of intermediate language in target language object text is described.

Language and compiler design are fundamental aspects of computer science. High-level languages are how most developers interact with computers, so it's hard to overstate the significance of compiler engineering or the aesthetics of language syntax. C# is a general-purpose high-level language that was created by Anders Hejlsberg at Microsoft in 2000, and was open-sourced in

A compiler and runtime support mechanism is described and demonstrated. The methods presented are capable of solving a wide range of sparse and unstructured problems in scientific computing. The compiler takes as input a FORTRAN 77 program enhanced with specifications for distributing data, and the compiler outputs a message passing program that runs on a distributed memory computer. The runtime support for this compiler is a library of primitives designed to efficiently support irregular patterns of distributed array accesses and irregular distributed array partitions. A variety of Intel iPSC/860 performance results obtained through the use of this compiler are presented.

Object-oriented relationships, such as inheritance and covering can not be readily incorporated in classic data models. This thesis addresses this problem by the design and implementation of an object-oriented data model (O-ODM), that incorporates the object-oriented paradigm. A Multimodel and Multilingual Database System called M2DBS has been developed at the Naval Postgraduate School. This system incorporates the classic database data models along with a recently developed object-oriented data model (O-ODM). The problem addressed by this work is to design a new object-oriented data manipulation language (O-ODML) for the O-ODM. The approach is to develop and construct an O-ODML Compiler. Then assimilate the compiler with the Kernel Mapping System (KMS) of the M2DBS. The result of this thesis is a compiler for the O-ODML of the O-ODM. This O-ODML compiler takes an O-ODM query converts it into a low level intermediate language before translating it into a format that the Real Time Monitor can execute on the M2DBS. (AN)

The programmer's most powerful tool for controlling complexity in program design is abstraction. We seek to use abstraction in the design of concurrent programs, so as to separate design decisions concerned with decomposition, communication, synchronization, mapping, granularity, and load balancing. This paper describes programming and compiler techniques intended to facilitate this design strategy. The programming techniques are based on a core programming notation with two important properties: the ability to separate concurrent programming concerns, and extensibility with reusable programmer defined abstractions. The compiler techniques are based on a simple transformation system together with a set of compilation transformations and portable run-time support. The transformation system allows programmer-defined abstractions to be defined as source-to- source transformations that convert abstractions into the core notation. The same transformation system is used to apply compilation transformations that incrementally transform the core notation toward an abstract concurrent machine. This machine can be implemented on a variety of concurrent architectures using simple run-time support.

This book is useful for those who are interested in knowing the underlying principles of a Compiler that is used for compiling high-level programming languages. This book actually guides you step by step in a lucid and simple way how to design a compiler ultimately. I am guessing you have compiled a high-level program some time or the other or rather, you do it on a regular basis; then this book would come handy for you because it opens all the mysteries to the functioning and designing of a compiler!

Classic data models such as the Relational and Hierarchical do not have capabilities to handle both of the object-oriented relationships, inheritance and covering. Therefore, the problem addressed by this work is to design and implement a completely new data model that embodies the object-oriented paradigm. With such an object-oriented data model (O-ODM), the direct modelling of a variety of database applications becomes possible. Database research at the Naval Postgraduate School has produced a Multimodeland Multilingual Database System called M2DBS. M2DBS currently supports all the classic database data models as well as a newly developed O-ODM. The approach taken is to first develop and build an entirely self-sufficient O-ODDL Compiler. Then, incorporate this compiler into the Kernel Mapping System (KMS) of the M2DBS. The results of this thesis is a compiler for the object-oriented data definition language (O-ODDL) of the O-ODM. This O-ODDL compiler takes an O-ODM database specification as input and does an automatic translation into the data format recognized by the M2DBS.

The hardware of floating-point MULTIPLY, ADD, and SUBTRACT units are designed to support the multiplication, addition, and subtraction operation necessary in the Fast Fourier Transform (FFT). In this thesis, the IEEE floating-point standard is adopted and scaled down to 16 bits, but the exponent is an excess-8 number represented using radix-2. A 16 bit reduced word size floating-point arithematic unit for high speed signal analysis was implemented. The layout verification, functional simulation, and timing analysis of these units have been performed on the Genesil Silicon Compiler (GSC) system that was developed to overcome the shortcomings of the time consuming custom layout methods. The design of this thesis work can be used for further investigation of the high speed, pipelined floating-point arithmetic units.

The technique of formal abstraction provides an appropriate tool for specifying an interface between layers of computer hardware and software. An abstract machine called AM has been built to address the problem of portability and reusability of software. This thesis is the design and implementation of a C Compiler for this abstract machine.

The document describes the FORTRAN transcribes used in conjunction with the Paralyzer on the Illiac 4 computer. After the Paralyzer has made its transformations on the original FORTRAN program, the transcriber can output the newly created program in standard FORTRAN source format. The output file can then be edited and fed back to the FORTRAN compiler. Storage allocator routines are described along with flow analysis routines and the Macro Expander and Optimizer phases.

Among our research goals is the development of 'mechanical design compilers'; that is, programs which take as input a schematic (or other high- level description) of a mechanical design, plus specifications and a cost function, and return a description of the optimal implementation of the design, sufficiently detailed to support manufacture. Such programs should decrease design time and cost, increase design quality, and allow designers to explore more alternatives in greater depth. We have chosen to work initially in the domain of mechanical and hydraulic power transmission systems built from cataloged components. For this domain we have substantially accomplished our goal; this paper presents the evidence for that success, and discusses its limitations. After mentioning some related work, we provide a very brief over-view of the compiler, intended only to allow the reader to understand our performance evaluation. Artificial intelligence.

A Sense/Compute/Control (SCC) application is one that interacts with the physical environment. Such applications are pervasive in domains such as building automation, assisted living, and autonomic computing. Developing an SCC application is complex because: (1) the implementation must address both the interaction with the environment and the application logic; (2) any evolution in the environment must be reflected in the implementation of the application; (3) correctness is essential, as effects on the physical environment can have irreversible consequences. The SCC architectural pattern and the DiaSpec domain-specific design language propose a framework to guide the design of such applications. From a design description in DiaSpec, the DiaSpec compiler is capable of generating a programming framework that guides the developer in implementing the design and that provides runtime support. In this paper, we report on an experiment using DiaSpec (both the design language and compiler) to develop a standard robotics application. We discuss the benefits and problems of using DiaSpec in a robotics setting and present some changes that would make DiaSpec a better framework in this setting.

The trends in software development are towards larger programs, more complex programs, and more use of programs as 'component software'. These trends mean that the features of modern programming languages are becoming more important than ever before. Programming languages need to have features such as strong typing, a module system, polymorphism, automatic storage management, and higher order functions. In short, modern programming languages are becoming more important than ever before. Even though modern programming languages are becoming more important than ever before, programmers have traditionally faced a dilemma: programs written in these languages traditionally have had lower performance than programs written in more conventional, but error-prone languages. This thesis studies this problem in the context of one particular modern programming language, Standard ML. Standard ML contains all the language features mentioned previously and more. The author uses an empirical approach to understand where Standard ML programs spend their time and how to improve the performance of Standard ML programs though better optimization. The thesis contains two main results. First, it is found that a 'pay-as-you-go' compilation strategy, where programmers pay for advanced language features only when they use them, is a practical strategy for compiling Standard ML. In fact, this strategy produces better code overall than a strategy that makes advanced language features run fast at the expense of slowing down programs that do not use those language features. Second, compilers for Standard ML should focus on generating good code for the frequently-executed parts of programs.

This project considered various sources of power consumption in general purpose high-performance and embedded processors and developed techniques for lowering the power consumption without significant sacrifice in performance. We have designed low power data caches and low power external data buses that can he used for both superscalar and embedded processors. For superscalar processors we have designed low complexity memory disambiguation mechanism, power efficient instruction issue mechanism, and load/store reuse techniques. For embedded processors we have developed techniques that allow us to achieve performance while operating on compacted code and data. The various techniques that were developed have been implemented as part of gcc compiler and the FAST simulation system. Experimentation was carried to demonstrate the utility of the techniques.

Testability issues concerning the need for including Design for Testability (DFT) techniques in VLSI (Very Large Scale Integration) designs are discussed. Types of fault models, the use of fault simulation and the DFT techniques of Scan Path and Built in Test are described. An engineering methodology that uses the Genesil Silicon Compiler to produce a VLSI design, DFT-CHIP, which utilizes the DFT Scan Path technique is presented. Included are the procedures for using Genesil's simulation, timing analysis and automatic test generation features. The steps taken to fabricate the DFT-CHIP design through MOSIS are discussed. The methodology used to test the fabricated DFT- CHIP design on the Tektronix DAS 9100 tester is described. Appendix A and Appendix B provide copies of the Genesil check functions written for use during simulation on the DFT-CHIP design. Appendix C specifies the Genesil timing information for the DFT-CHIP design. Appendix D lists the conversion program which translates Genesil produced test vector files to the file format used during testing on the Tektronix tester.

Construction within the Meta language for both language and target machine specification is reported. The elements of the function language as a meaning and syntax are presented, and the structure of the target language is described which represents the target dependent object text representation of applications programs.

The purpose of this project was to introduce the language Ada into our complier design curriculum as the development language. To this end our course which had been traditionally taught using Pascal was to be reworked so that the programming portion would now be done in Ada. In addition, while a subset of Pascal had been normally used as the target design complier, the course was now to have a language similiar to a subset of Ada as the target design complier. This in fact was carried out and the ensuing report describes some aspects of the course development

Compiler design is a course that discusses ideas used in construction of programming language compilers. Students learn how a program written in high level programming language and designed for humans understanding is systematically converted into low level assembly language understood by machines. We propose and implement a Case-based and Project-based Learning environment for teaching important Compiler design concepts (CPLC) to B.Tech third year students of a Delhi University (India) college. A case is a text that describes a real-life situation providing information but not solution. Previous research shows that case-based teaching helps students to apply the principles discussed in the class for solving complex practical problems. We divide one main project into sub-projects to give to students in order to enhance their practical experience of designing a compiler. To measure the effectiveness of case-based discussions, students complete a survey on their perceptions of benefits of case-based learning. The survey is analyzed using frequency distribution and chi square test of association. The results of the survey show that case-based teaching of compiler concepts does enhance students skills of learning, critical thinking, engagement, communication skills and team work.

This paper presents the ideas underlying a computer program that takes as input a schematic of a mechanical or hydraulic power transmission system, plus specifications and a utility function, and returns catalog numbers from predefined catalogs for the optimal selection of components implementing the design. Unlike programs for designing single components or systems, this program provides the designer with a high level 'language' in which to compose new designs. It then performs some of the detailed design process for him. The process of 'compilation', or transformation from a high to a low level description, is based on a formalization of quantitative inferences about hierarchically organized sets of artifacts and operating conditions. This allows compilation without the exhaustive enumeration of alternatives. The paper introduces the formalism, illustrating its use with examples. It then outlines some differences from previous work, and summarizes early tests and conclusions. Keywords: Computer aided design; Computer programs; Mechanical design; Quantitative inference; Qualitative reasoning; Constraint propagation.
