Flat Assembler is a fast and efficient self-assembling 80x86 assembler. It supports x86 and x86-64 instruction sets with MMX, 3DNow!, SSE up to SSE4, AVX, AVX2, and XOP extensions. It can produce output in binary, MZ, PE, COFF, or ELF format. It includes powerful but easy-to-use macroinstruction support and does multiple passes to optimize the instruction codes for size. It is written entirely in assembly language.
Erasm++, the Embedded Runtime Assembler in C++, is an Embedded Domain Specific Language (EDSL) in C++ for runtime code generation on Intel 64/IA-32 architectures. It supports complete compile-time syntax checking, and its code generators run very quickly because necessary data are computed statically. Also included are GenericDsm, a fast and generic instruction decoder library which supports "pattern matching" against the decoded instructions, and MetaPrelude, a Haskell-like lazy metaprogramming library that helps implementing EDSLs in C++.
J51 is a Intel MCS51 emulator with all the standard integrated peripherals. A disassembler with an integrated debugger is also included. Standard peripherals emulated are Timer 0/1 (Mode 0, 1, 2, and interrupts), serial interface in polled and interrupt mode, standard I/O, and ports 0 to 4. Microprocessors emulated are the Intel MCS 8051 (no peripherals), Intel 8051, Intel 8052, Philips LPC674, and Philips LPc900.
nescom is a suite of assembler and linker tools for the CPU used in the NES/Famicom. It can produce xa65-compatible relocatable object files, IPS format patches, raw binary images, and ROM images in INES format. nescom is a sister project of snescom, and shares much of the syntax and features.
The Amazing Awk Assembler (aaa) is a primitive assembler written entirely in awk and sed. It is quite slow, the input syntax is eccentric and rather restricted, and error checking is virtually nonexistent, but it does work. Furthermore it's very easy to adapt to a new machine, provided the machine falls into the generic "8-bit-micro" category.
The Perl Dev Kit (PDK) provides essential tools for building and deploying Perl applications. PDK features cross-platform wrapping and application builders for various operating systems, plus a suite of tools to speed development time and improve code quality and consistency across teams.
