Open Source Linux Debuggers

The "Open On-Chip Debugger" provides JTAG/SWD access from GDB (or directly with TCL scripts) to processors with ARM and MIPS based cores. See website for full list of supported targets.

A disassembler for the linux platform. Currently this supports x86 ELF files assumed to be written in C and output to intel- syntax assembly language; however the design is modular and replacements for any of these can be written.

Udis86 is an easy-to-use minimalistic disassembler library for the x86 and x86-64 instruction set architectures. The primary intent of the design and development of udis86 is to aid software development projects that entail binary code analysis.

Unfortunately this project has been suspended. If you wish to continue its development on your own, please feel free to contact me. UnPyc is a tool for disassembling, analyzing and decompiling Python's *.pyc and *.pyo files. UnPyc supports Python 2.5, 2.6.

Disassembler for Windows(95-XP), currently supports PE, NE, MZ, COM and "unknown" executable formats. Includes also OS independent console version (but requires x86). Output syntax similar to NASM .

DiDasm is a small and fast disassembler, useful for Windows kernel developers. Advantages: - highly portable, has minimal runtime requirements (C runtime); - core libraries do not require any external components; - includes instructions emulator (diana_processor); - has stream oriented design; Supported platforms: i386, amd64 Supported instructions: x586/amd64/FPU/MMX/SSE/SSE2

AsmTrace traces ELF executables, showing registers and disassembly. Triggers can enable and disable tracing.

mt6502dis is an interactive disassembler for parsing 6502 machine code. It is a GUI based program and uses the GTK+1 or GTK+2 toolkits.

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.

IMAVR is Atmel AVR 8-bit RISC chip emulator for UNIX. You can run your code before programming to chip. Embedded simple debugger and disassembler. Emulate wide range of AVR chip, wide range of their modules: EEPROM,USART, timers and so on.

Bits and Pieces is an interactive 6502 disassembler.

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.

QDisassembler Interactive Disassembler

This is a port of several development tools for Freescale M68HC08/HCS08 embedded microcontrollers families. Currently work is focused on binutils (as,ld), gdb and sim port. GCC, newlib, etc. porting will start after finishing the main as/ld support.

VirtuAL3101 provides a series of tools to develop effects using the AL3101 DSP from Alesis. It includes an assembler/disassembler, a simulator, an application generator with its graphical interface and various effects.

a powerful disassembler for x86

Disassembler for linux: will try to provide a gui driven tool to disassemble executables. Written in C++, uses gtk libraries for the gui, and will disassemble binaries from a number of OSses.

Yet another IDAPro-like disassembler.

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.

lida is a fast feature packed interactive ELF disassembler / code-/cryptoanalyzer based on bastards libdisasm (see bastard project).

A standalone powerpc disassembler written as a wrapper over GNU libopcode library. It accepts the opcode ( in hex or decimal ) as it's argument and spits the disassembled output. Recently, a reference assembler has been added. It takes the instruction in string form and spits the assembled 32-bit opcode.It's not fully tested and may not work always.

PPCD is very accurate PowerPC ISA (and derivative processors) disassembler. Currently supported models are: Generic-32, Generic-64 and Gekko. PPCD is free opensource. You can use it in your applications without mention.

playstation (psx) development tools: includes disassembler, code profiler, and cd mastering tools (split off from the World Foundry GDK).

Tool for using syntax highlighting, code competion, ect, in sd.
