    NASM

    NASM

    A cross-platform x86 assembler with an Intel-like syntax

    NASM (Netwide Assembler) is a widely used, open-source assembler for the x86 architecture that provides a flexible and portable way to write low-level machine code using an Intel-style syntax. It is designed to support a wide variety of output formats, making it suitable for different operating systems and development environments. NASM is known for its simplicity and clarity, allowing developers to write assembly code that is both readable and efficient. It is commonly used in system programming, operating system development, and performance-critical applications where direct hardware control is required. The assembler is highly portable and can be used across multiple platforms, making it a standard tool in many low-level programming workflows. Its maturity and widespread adoption have made it a reliable choice for developers working close to the hardware. Overall, nasm serves as a foundational tool for understanding and implementing low-level software systems.

    Easy Beginner's Environment in QT

    Easy Beginner's Environment in QT

    This is a port of the ebe programming environment to QT.

    The ebe programming environment is a nice IDE designed for developing Assembly programs. It also handles C and C++ programs as well since there was not much extra effort. It used to support Fortran and this could return if people want Fortran. This project is an effort to recode ebe using C++ and QT. Originally ebe was coded using Python, Tkinter and Pmw, which worked out pretty well. The QT environment offers substantially better GUI controls. The most obvious difference is that Python ebe has a lot of separate windows, while the QT ebe will use 1 main window and a collection of dockable subwindows. This will make it easier to use.

    m6811dis

    m6811dis

    M6811 Code-Seeking Disassembler

    The M6811 Code-Seeking Disassembler is a command-line tool that lets you enter known starting vectors for a given code image for the 6811 micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its companion Fuzzy Function Analyzer uses DNA Sequence Alignment Algorithms to locate similar code in multiple binaries, facilitating reverse-engineering. Originally written to analyze code from GM automotive engine controllers, but is useful anywhere a 6811 micro is being used. Version 1.0 was written in Borland Pascal in April 1996, and updated to v1.2 in June 1999. It was later rewritten to C++ in July 1999 through Jan 2000. While it's been freely available since its creation, it's being released here as an open-source project so the world can better use it as it sees fit. Version 2.0 is completely reworked in 2014 to compile and run with GCC and STL to make it fully portable and accessible to all computer platforms.

    Code Red Sim

    Code Red Sim

    A low-power ISA design and simulator for a 2010 IEEE competition

    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.

    UniSIMD-assembler

    SIMD macro assembler unified for ARM, MIPS, PPC and x86

    UniSIMD assembler is a high-level C/C++ macro assembler framework unified across ARM, MIPS, POWER and x86 architectures. It establishes a subset of both BASE and SIMD instruction sets with clearly defined common API, so that application logic can be written and maintained in one place without code replication. The assembler itself isn't a separate tool, but rather a collection of C/C++ header files, which applications need to include directly in order to use. At present, Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512 (32/64-bit x86 ISAs), ARMv7 NEON/NEONv2, ARMv8 AArch32 and AArch64 NEON, SVE (32/64-bit ARM ISAs), MIPS 32/64-bit r5/r6 MSA and POWER 32/64-bit VMX/VSX (little/big-endian ISAs) are mostly implemented (/w horizontal reductions) although scalar improvements, wider SIMD vectors with zeroing/merging predicates in 3/4-operand instructions are planned as extensions to current 2/3-operand SPMD-driven vertical SIMD ISA. See README file.

    asm68c

    Assembles M6800 and 6801 assembly language source code. (and Forth)

    A simple absolute mode assembler for 6800/6801. Handles the complete published set of opcodes/mnemonics. Mostly source-language compatible with the common assemblers in use circa 1985, but no macros. Now uses standard LDAA syntax by default. Produces basic S1/S9 object files and assembly listings, and now binary and MC-10 compatible cassette images. (This is for the 8-bit 6800, not the 16/32 bit 68000/coldfire processors.)
