Turbo Assembler (sometimes shortened to the name of the executable, TASM) is an assembler for software development published by Borland in 1989. It runs on and produces code for 16- or 32-bit x86 MS-DOS and compatibles for Microsoft Windows .
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.
Nevertheless for the most common targets the LLVM MC (machine code) project provides an assembler both as an integrated component of the compilers and as an external tool. Some other self-hosted native-targeted language implementations (like Go , Free Pascal , SBCL ) have their own assemblers with multiple targets.
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.
Furthermore, on a modern x86 system, BIOS calls can only be performed in Real mode, or Virtual 8086 mode. v8086 is not an option in Long mode. This means that a modern operating system, which operates in Protected mode (32 bit), or Long mode (64 bit), would need to switch into real mode and back to call the BIOS - a hugely expensive operation.
Support for the various x86 memory models was provided by inline assembly, compiler options, and language extensions such as the "absolute" keyword. The Turbo Assembler, TASM, a standard x86 assembler independent of TP, and source-compatible with the widely used Microsoft Macro Assembler MASM, was supplied with the enhanced "Borland Pascal ...
The sports streaming game has a new player: DirecTV. The TV provider is launching MySports, a sports subscription streaming service with 40 channels including ESPN, Fox Sports, and the NFL Network.
The Netwide Assembler (NASM) is an assembler and disassembler for the Intel x86 architecture. It can be used to write 16-bit, 32-bit and 64-bit programs. It is considered one of the most popular assemblers for Linux and x86 chips. [3] It was originally written by Simon Tatham with assistance from Julian Hall.
