Open Source Java Assemblers

RARS, the RISC-V Assembler, Simulator, and Runtime, will assemble and simulate the execution of RISC-V assembly language programs. Its primary goal is to be an effective development environment for people getting started with RISC-V.

It has a light weight API similar with ASM. * dex-translator is designed to do the convert job. It reads the dex instruction to dex-ir format, after some optimize, convert to ASM format. * dex-ir used by dex-translator, is designed to represent the dex instruction dex-tools tools to work with .class files. * d2j-smali disassemble dex to smali files and assemble dex from smali files. different implementation to smali/baksmali, same syntax, but we support escape in type desc "Lcom/dex2jar\t\u1234;" * dex-writer write dex same way as dex-reader.

Dedexer is a disassembler tool for Android DEX files. The purpose is to create Jasmin-like source files from DEX files.

JReversePro is a Java Decompiler / Disassembler written in Java. Facility to view the ConstantPool contents is available. AWT, Swing and command-line versions are present.

Java Decompiler, Disassembler and Bytecode debugger. Decompiler supports Java 5 (e.g. generics, for-each loops etc). Debugger allows user to step through each bytecode and view program state. Contains Swing GUI.

Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs

A open source java card virtual machine implementation. And also some part of the VM code can be used as part of kinds of tools such as javacard bytecode disassembler.

small & symple disassembler, resource unpacker and flowchart graphical editor

This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

The aim of this project is to create a fully functional C compiler that translate into bytecode.

JEST will be the Java bytecode engineering Swiss-Army Jackhammer. It will include a disassembler, class browser, obfuscator, optimizer, class editor, and bytecode debugger, and have an intuitive GUI.

Jout (Java optimization utility toolkit) is a complete workground for editing .class files. It includes automatic and manual optimization.

JasminParser is a Jasmin (Java Assembler, .j file) compiler based on the Apache BCEL. JasminParser provides a disassembler and an assembler to convert java classes and jasmin files to each other.

Lilac is a tool suite, which contains an assembler and a disassembler for the JVM (Java Virtual Machine) bytecode. The assembler takes textual representations of Java classes, written in an assembler-like syntax, and converts them to binary Java class files, which can be loaded into JVM. The disassembler takes binary Java class files and creates out of them assembler files suitable for the assembler. In general (except for some very rare cases) Lilac tools allow a perfect round-trip, that is, if you disassemble a class file and then assemble it again, without making any changes, you'll get the original file.

Q Disassembler is a flexible disassembly engine that aims to provide precise information about machine instructions while maintaining OS-independence and performance.

The aim of this project is to create a fully functional COBOL compiler that translate into Java or directly into bytecode.

bMARS is a java implementation of Redcode virtual machine MARS - "Memory Array Redcode Simulator"

dxcut is a library for reading, editing, and writing dex and odex files which contain the class definition and Dalvik bytecode used by the Android operating system. This project includes a disassembler/decompiler, dex optimizer, and hooking utils.

jbytecode is a Java bytecode disassembler/assembler written in Python. Dissasembly code is aligned with Java bytecodes in the class file so modification and re-assembly is always possible, even when class is obfuscated.

This is a swf-decoder and disassembler

nsL is a new C-like programming language for writing NSIS installation wizards (http://nsis.sourceforge.net). The nsL assembler takes nsL code and translates it into original NSIS script which can then be compiled.
