Bytecode Transformation for Portable Thread Migration in Java

by Takahiro Sakamoto, Tatsurou Sekiguchi, Akinori Yonezawa , 2000
"... This paper proposes a Java bytecode transformation algorithm for realizing transparent thread migration in a portable and efficient manner. In contrast to previous studies, our approach does not need extended virtual machines nor source code of target programs. The whole state of stack frames is sav ..."

A Portable research framework for the execution of java bytecode

by Etienne Gagnon , 2002
"... Compilation to bytecode paired with interpretation is often used as a technique to easily build prototypes for new programming languages. Some languages, includ-ing Java, push this further and use the bytecode layer to isolate programs from the underlying platform. Current state-of-the-art commercia ..."

the question: How fast can a portable, easily modifiable Java bytecode interpreter be? In order to address this question, we have designed and developed the SableVM research framework, a portable interpreter-based Java virtual machine written in portable C.

Dependence Analysis of Java Bytecode

by Jianjun Zhao - In IEEE Annual International Computer Software and Applications Conference , 2000
"... Understanding program dependencies in a computer program is essential for many software engineering tasks such as program understanding, testing, debugging, reverse engineering, and maintenance. In this paper, we present an approach to dependence analysis of Java bytecode, and discuss some applicati ..."

applications of our technique, which include Java bytecode slicing, understanding, and testing. 1 Introduction Java is a new object-oriented programming language and has achieved widespread acceptance because it emphasizes portability [1]. In Java, programs are being compiled into a portable binary format call

The Functions of Java Bytecode

by Mark P. Jones - In Workshop on the Formal Underpinnings of the Java Paradigm , 1998
"... Java bytecode provides a portable representation for programs that allows executable content to be embedded in web pages, transferred across a network, and executed on a remote user's machine. Features like these provide many new opportunities for developers, but special precautions must be tak ..."

Speculatively vectorized bytecode

by Erven Rohou , Sergei Dyshel , Dorit Nuzman , Ira Rosen , Kevin Williams , Albert Cohen , Ayal Zaks - In Proceedings of the International Conference on High Performance and Embedded Architectures and Compilers (HiPEAC , 2011
"... ABSTRACT Diversity is a confirmed trend of computing systems, which present a complex and moving target to software developers. Virtual machines and just-in-time compilers have been proposed to mitigate the complexity of these systems. They do so by offering a single and stable abstract machine mod ..."

-in-time vectorization. Vapor SIMD first applies complex ahead-of-time techniques to vectorize source code and produce bytecode of a standard portable format. Advanced JIT compilers can then quickly tailor this bytecode to exploit SIMD capabilities of appropriate platforms, yielding up to 14.7× and 11.8× speedups on x86

JAVA BYTECODE OBFUSCATION by

by Michael R. Batchelder , 2007
"... Programs written for machine execution will always be susceptible to information theft. This information can include trademarked algorithms, data embedded in the program, or even data the program accesses. As technology advances computer scientists are building more and more powerful tools for rever ..."

for reverse-engineering such as decompilers. The Java programming language is particularly open to reverse-engineering attacks because of its well-defined, open, and portable binary format. We examine one area of better-securing the intellectual property of a Java program; obfuscation. Obfuscation of a

ByCounter: Portable Runtime Counting of Bytecode Instructions and Method Invocations

by Michael Kuperberg, Martin Krogmann, Ralf Reussner
"... For bytecode-based applications, runtime instruction counts can be used as a platform-independent application execution metric, and also can serve as the basis for bytecode-based performance prediction. However, different instruction types have different execution durations, so they must be counted ..."

, and it can be used without modifications on any JVM. We evaluate the presented approach by successfully applying it to multiple Java applications on different JVMs, and discuss the runtime costs of applying ByCounter to these cases. Key words: Java, bytecode, counting, portable, fine-grained

Using Bytecode Instruction Counting as Portable CPU Consumption Metric

by Walter Binder, Jarle Hulaas - Electr. Notes Theor. Comput. Sci , 2006
"... Accounting for the CPU consumption of applications is crucial for software development to detect and remove performance bottlenecks (profiling) and to evaluate the performance of algorithms (benchmarking). Moreover, extensible middleware may exploit resource consumption information in order to detec ..."

bytecode instructions. We explain the advantages of this approach to CPU management and present five case studies that show the benefits in different settings.

Exact and Portable Profiling for the JVM Using Bytecode Instruction Counting

by Walter Binder, Jarle Hulaas
"... This paper presents a novel profiling approach, which is entirely based on program transformation techniques in order to enable exact profiling, preserving complete call stacks, method invocation counters, and bytecode instruction counters. We exploit the number of executed bytecode instructions as ..."
