x86 assembly language includes instructions for a stack-based floating-point unit (FPU). The FPU was an optional separate coprocessor for the 8086 through the 80386, it was an on-chip option for the 80486 series, and it is a standard feature in every Intel x86 CPU since the 80486, starting with the Pentium.
The assembler is contained in one 32K executable and can directly produce a COM file or an object file for use with a standard linker. It comes with a debugger , D86 . [ 1 ] [ 2 ] Speed of assembly is a primary selling point, and Isaacson claimed that A86 could assemble 100,000 lines of source per second on a Pentium II or better. [ 3 ]
The DOS executable XLT86.COM [12 KB] translates Intel 8080 assembly language source code to Intel 8086 assembly language source code. Despite its name this implementation in 8086 assembly is not related to Digital Research's earlier and much more sophisticated XLT86.) Albo, Julián (2009-04-24).
The 8086 [3] (also called iAPX 86) [4] is a 16-bit microprocessor chip designed by Intel between early 1976 [citation needed] and June 8, 1978, when it was released. [5] The Intel 8088, released July 1, 1979, [6] is a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), [note 1] and is notable as the processor used in the original IBM ...
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.
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 .
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]
The compiler was subsequently repackaged by Microsoft under a distribution agreement as Microsoft C version 2.0. [4] Microsoft developed their own C compiler that was released in April 1985 as Microsoft C Compiler 3.0. [5] Lattice was purchased by SAS Institute in 1987 and rebranded as SAS/C. After this, support for other platforms dwindled ...
