What are the three features of assembly language?
Below are the advantages:
- It allows complex jobs to run in a simpler way.
- It is memory efficient, as it requires less memory.
- It is faster in speed, as its execution time is less.
- It is mainly hardware-oriented.
- It requires less instruction to get the result.
- It is used for critical jobs.
What is a pass in assembly language?
The ARM® assembler reads the assembly language source code twice before it outputs object code. Each read of the source code is called a pass. The assembler cannot know the address of the forward reference label until it reads the definition of the label. During each pass, the assembler performs different functions.
What are the features of assemblers?
1.2 Key features of the assembler
- Unified Assembly Language (UAL) for both ARM and Thumb® code.
- Vector Floating Point (VFP) instructions in ARM and Thumb code.
- Directives in assembly source code.
- Processing of user-defined macros.
What are the 3 sections of assembly program?
Assembly – Basic Syntax An assembly program can be divided into three sections − •The data section, •The bss section, and •The text section.
What are the main features of assembly language?
It mainly depends on the architecture of the system, whether it is the operating system or computer architecture. Assembly Language mainly consists of mnemonic processor instructions or data and other statements or instructions.
Is the assembly language a processor dependent language?
Assembly language (or Assembler) is a compiled, low-level computer language. It is processor-dependent, since it basically translates the Assembler’s mnemonics directly into the commands a particular CPU understands, on a one-to-one basis. These Assembler mnemonics are the instruction set for that processor.
What do assembler directives tell the assembler about?
The assembler directives or pseudo-ops tell the assembler about the various aspects of the assembly process. These are non-executable and do not generate machine language instructions.
Which is the most popular assembly language for MS-DOS?
For MS-DOS PCs, the most popular Assembly language was Microsoft Macro Assembler, or MASM. As with most popular compilers, MASM was upgraded on a regular basis. Most of this discussion refers to version 5.0 or later, which simplified the use of certain directives and included support for instructions available only on 80286 and 80386 CPUs.
