Open Source Assembly Debuggers

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++.

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.

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.

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

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)

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.

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

Denwer is a collection of often-used web-servers for web-programmers. It is used to debug web-sites under Win32. Denwer includes: friendly installer; Apache; PHP; MySQL; Perl; virtual host management system; phpMyAdmin; sendmail stub; start/stop manager.

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.

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

Scripting Language plugin for Olly Debugger 1.10

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.

NEmu is an emulator/simulator for exploring computer architecture. It provides a virtual machine, a debugger, and simulations of various cpus and hardware. NEmu is built on top of ALib, my own application framework.

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.

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

CMON51 is a monitor for the 8051/8052, written in C and assembly.

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.

GNUDE is a complete suite of GNU C, C++, Fortran, and Java Cross Compilers, and the GDB CPU Simulator and Debugger for embedded microprocessor applications development. Targets development for ARM7, ARM9, and XScale applications.

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.

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/

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.

IDE with debugger integrated for develop with z390 emulator. English and Spanish Interface is released. * Added an automatic z390 portable mainframe validator to be configuration easily

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

ATmon is a bootloader and monitor tool for the Atmel ATmega32 microcontroller.
