Open Source Windows Cross Compilers

Integrated Development Environment for some microcontrollers based on 8051(e.g. AT89S8253). Supported languages are Assembly and C. It has its own simulator, assembler, editor and many other tools. See the project web site for more details and the newest updates.

ACME is a free cross assembler released under the GNU GPL. It can produce code for the following processors: 6502, 6510 (including illegal opcodes), 65c02 and 65816. ACME supports the standard assembler stuff like global/local/anonymous labels, offset assembly, conditional assembly and looping assembly. It can include other source files as well as binaries while assembling. Calculations can be done in integer or float mode. Oh, and it is fast.

JWasm is a Masm-compatible assembler. It supports 16-, 32- and 64-bit code, instructions up to AVX and various output formats. It's written in C.

This is a Windows command line based cross development environment for the M68K/ColdFire family of processors built from the latest stable release of GCC (currently 13.1.0). I recently incorrectly built 12.2.0 so have deleted it. Also included is Gnu make along with the necessary MinGW dlls to make it all work. I build this tool chain, from time to time, to use for testing Flash Insight, a device programmer that is available on my website. I want to make it available to the embedded development community since building gcc under MinGW isn't a trivial exercise and if you're like me you probably just want to work on your project and not fiddle with building tool chains. Unzip the archive to the location of your choice, include the top level "bin" directory in your path and start developing.

This is a Windows command line based cross development environment for Power PC built from the latest stable release of GCC (currently 13.1.0). I built 12.2.0 incorrectly so I've deleted it. Also included is Gnu make along with the necessary MinGW dlls to make it all work. I build tool chains for other targets, from time to time, to use for testing Flash Insight, a device programmer that is available on my website. Flash Insight doesn't currently support PowerPC but once I have the tool chain building for one target it generally builds for all targets. I want to make this tool chain available to the embedded development community since building gcc under MinGW isn't a trivial exercise and if you're like me you probably just want to work on your project and not fiddle with building tool chains.

zDevStudio is an open source cross-platform IDE based on Pasmo compiler designed to help coders and retrocoders to develop software for Zilog Z80 8 bit CPU.

Z88DK is a complete Z80 / Z180 development kit that includes C compiler, assembler, linker, a tool for generating executables in a number of formats, and miscellaneous other tools. Over 80 machines are directly supported out of the box including standalone Z80 and Z180 embedded systems. Z88DK's extensive assembly language libraries give it significant performance advantages over other Z80 C Compilers. Building software for standalone or generic Z80 systems: https://www.z88dk.org/wiki/doku.php?id=libnew:target_embedded Visit us at github for the current version with bugfixes and new features: https://github.com/z88dk/z88dk

Win32 hosted tools to cross compile to DJGPP v1 (go32) for MS-DOS. Now includes GCC 1.27 aka the first version available to support the i386 processor.

A cross assembler for the ubiquitous Intel(tm) 8048 family of microcontrollers. Also supports compatible parts such as the 8035, 8039, 8049, etc. Binaries are available for Windows, Linux and Mac OSX.

Dev65 is a macro assembler, linker and librarian suite for the 6501, 6502, 65C02, 65816 and 65832 family of microprocessors coded in Java for portability. The code is based on a framework that could support other system architectures.

asxa: Cross Assembler for NXP XA-51 Microcontrollers. Included is a monitor in XA assembly language with a disassembler a a debugger.
