Open Source Assembly 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.

WinAVR (tm) is a suite of executable, open source software development tools for the Atmel AVR series of RISC microprocessors hosted on the Windows platform. Includes the GNU GCC compiler for C and C++.

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.

SkyEye is a very fast full system simulator which takes llvm as IR of dynmic compiled framework.. It can simulate series ARM, Coldfire,Mips, Powerpc, Sparc, x86, TI DSP and Blackfin DSP Processor. Also can simulate multicore system by the multicore of host. The commercial support is provided by DigiProto Co. (http://www.digiproto.com)

Softx86 is a library that provides software emulation of an Intel 80x86 CPU. The library takes care of executing opcodes and handling exceptions while the host application is responsible for providing simulated RAM, I/O devices, external signals.

CDK4AVR stands for Cross Development Kit for Atmels AVR RISC processor serie and should you support with a comprehensive Assembler and C development environment for even this processor familie under Linux or similar host systems.

ELENA is a general-purpose, pure object-oriented language with late binding. It promotes more object-oriented program design, reusable and more standardized code. The package includes compiler, IDE, ELENA libraries and samples

Scripting Language plugin for Olly Debugger 1.10

The prc-tools project currently consists of patches to binutils, gdb, and GCC to support Palm OS, along with several post-linker tools.

This project covers the development of 3rd-party tools for the "Wilson S1MP3 Player", some chinese device manufactured by Actions, with very low customer support. Generally you will find here development tools to access and alter the device firmware.

Software Development Kit for the Nintendo(tm) Gameboy Advance(tm) based on GCC.

A retargettable micro-controller and embedded system emulator architecture, providing common supports to emulate various types of micro-processors & devices on an x86 PC. Development of emulation for Arduino and various shields is just about to be launched in 2012.

A full development kit, based on XSCompiler. Multi-platform compiler and IDE, many libraries and examples. Uses an innovative programming language, an improved version of the standard and well-known C/C++.

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.

Jasmin is an interpreter for the x86 assembly language with a full-featured development environment aimed for educational purposes.

MINIMON is a Machine Language Monitor for the Commodore VIC-20. It is a combined hardware/software project: a cartridge for the computer's expansion port (with a cartridge extender for a secondary cartridge), plus firmware, which is the actual MINIMON monitor. MINIMON features all commands usually expected from a debugger/monitor: Memory dump and edit, Register dump and edit, Execute code from monitor, Direct Assembler and Disassembler (all documented opcodes of the NMOS 6502), Transfer/Compare/Fill/Hunt in memory blocks, Use of breakpoints with the BRK instruction, Load/Save/Verify with any storage device. The cartridge hardware expands upon the firmware features by supplying a de-multiplexer for the $9800..$9FFF I/Ox area (where the firmware is located per default) and a versatile reset button (with autostart inhibit for secondary cartridges). Size: only 2048 Bytes. Start with SYS 38912 Read 'instructions.12.txt' for further info.

Simulator for 486 processor. Can be customized for embedded system emulation.

Open On-Chip Debug Solution for Embedded Target Systems based primarily on ARM cores. This project has moved to sourceforge: https://sourceforge.net/projects/openocd/

psxdev.ru is home of the following projects: HLPSE (HLE PSX Emulator), HLPSD (HLE PSX DisASM), HLPStEst (HLE PSX Emulator (obsolete)), TIMGRAB (TIM extractor).

Adebug/Assemble is a pair of Debugger/Assembler for the MC68Xxx family running on Atari and Amiga computers. Years ago commercial product, now GPL.

CDK4MSP stands for Cross Development Kit for the Texas Instruments MSP430 MCUs and should you support with a comprehensive Assembler and C development environment for even this processor familie under Linux or similar host systems. It will present only f

CDK4NIOS stands for Cross Development Kit for Altera's soft core processor NIOS and should you support with a comprehensive Assembler and C/C++ development environment under Linux. It will present only free of fee tools, so you can use it without risks.

We provide a mechanism to trace the NPTL Library as few intrusive as possible for the application dynamics. The post-mortem analysis then allows measurements (contension,...) and understanding of hangs or bugs. No change in kernel or user application.

Minibug is a simple debugger that runs in the console. It has two windows and is controlled by the keyboard. One window shows disassembly, registers, memory, and breakpoints.
