Open Watcom Assembler or WASM is an x86 assembler produced by Watcom, based on the Watcom Assembler found in Watcom C/C++ compiler and Watcom FORTRAN 77. [1] [2] [3] Further development is being done on the 32- and 64-bit JWASM project, [4] which more closely matches the syntax of Microsoft's assembler.
The Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows.Beginning with MASM 8.0, there are two versions of the assembler: One for 16-bit & 32-bit assembly sources, and another (ML64) for 64-bit sources only.
[5] [6] FASM is completely written in assembly language and comes with full source. It is self-hosting and has been able to assemble itself since version 0.90 (May 4, 1999). FASM originally ran in 16-bit flat real mode. 32-bit support was added and then supplemented with optional DPMI support. Designed to be easy to port to any operating system ...
In version 0.90, Simon Tatham added support for an object-file output interface, and for DOS .OBJ files for 16-bit code only. [9] NASM thus lacked a 32-bit object format. To address this lack, and as an exercise to learn the object-file interface, developer Julian Hall put together the first version of RDOFF, which was released in NASM version ...
The 32-bit flat memory model of the 80386's extended protected mode may be the most important feature change for the x86 processor family until AMD released x86-64 in 2003, as it helped drive large scale adoption of Windows 3.1 (which relied on protected mode) since Windows could now run many applications at once, including DOS applications, by ...
These instructions are also available in 32-bit mode, in which they operate on 32-bit registers (eax, ebx, etc.) and values instead of their 16-bit (ax, bx, etc.) counterparts. The updated instruction set is grouped according to architecture ( i186 , i286 , i386 , i486 , i586 / i686 ) and is referred to as (32-bit) x86 and (64-bit) x86-64 (also ...

The 4-bit processors were programmed in assembly language or Forth, e.g. "MARC4 Family of 4 bit Forth CPU" [6] (which is now discontinued) because of the extreme size constraint on programs and because common programming languages (for microcontrollers, 8-bit and larger), such as the C programming language, do not support 4-bit data types (C ...
