Assembler :

Assembler refers to a computer program which provides a mechanism of taking computer instruction and converting them into a pattern of bits that the computer's processor can use to perform some basic operations.It is used to interpret software program which is written in assembly language into machine language, code and instructions that can be executed by a computerand it enables software  to  access, operate and manage a computer's hardware architecture and components.It converts the source code of assembly language into object code or an  Executable and Linking Format (ELF) relocatable object files executed by processor

The function of an assembler is to translate programs written in Assembly language into object modules. The object code will then be in a suitable form for processing by a Linkage Editor. The Assembler language is a symbolic representation of the machine language. The assembler such as the linkage editor is supplied as part of the operating system & executes under the control of an appropriate control program. It accepts, as an input, a source program written in the Assembler Language. The output from the assembler includes the object module listings:

  • Source module
  • Object code
  • Diagnostics
  • Cross-reference listings

An assembler program is made up of one or more control sections/CSECT. A control section is a smallest relocatable unit of the code. All the elements of a control section are loaded into an adjoining virtual storage location. They contain code, storage & constants. Assembler programs may process data in all the common formats. Data is defined with a DS - Data Storage/DC- Data Constant command. Symbols may be used instead of addresses. This means that symbols may be used with the meaningful names instead of explicit addresses in the base-displacement form. If this is done, the assembler will convert the implicit addresses of the symbol into explicit addresses required by the machine instructions.

Assembler is basically a one to one mapping to machine code. Assembly language is human readable code not the machine code.  No high-level language constructs are used and no nested expressions are there.

An assembler refers to a computer program that converts the assembly language program into machine language. Machine language refers to the computer understandable language. Translated program is known as the object program. An assembler that produces a machine code for a system and also run on that system is known as self assembler. And when an assembler generates the machine code for a system and run on the different system, then it is known as Cross assembler. Various steps for assembling a program are listed below:

  • Firstly, by using an input device, insert source program in Assembly language
  • Then use assembler to change it into the machine language
  • and in last, execute the program.

Assembler also checks the each instruction properly and generates the diagnostic messages. It can be divided into two types. Types of assemblers depend on the number of times it takes to read the source code. There are two types of assemblers are as follows:

  • One pass assembler: one pass assembler read the source code only once. This assembler converts the source code into machine code in the first part and also assigns the memory address to the variables.
  • Two pass assembler: this assembler divided its work in two phases. This assembles read the source code twice. First time, it reads all the variables properly and then assigns the memory address to variables. During the second pass, this assembler read the source code first then translate it source code into object code.

A computer will not understand any programming language. It understands only its machine language and assembler provide the machine language to computer. An Assembly program mainly consist three parts:

  • Machine instructions: it executes the object code with the help of microcontroller.
  • Assembler directives: it produces non executable codes such as data, messages, etc. Assembler directives mainly define the symbols and structure of a program.
  • Assembler controls: assembler controls set the all assembly modes.

Assembly language is an illustrative representation of machine language. Main function of an assembler is to convert the assembly language into object modules. Resultant code, which named as object code will be in a comfortable form for processing by linkage editor. This editor is executes under the control of a suitable program. List of object modules that involved in the output of assemblers:

  • Object code
  • Source module
  • Cross reference listing
  • Diagnostics

Moreover, For representing the low level machine operation, Assemble language uses mnemonic such as flag, architectural register, etc. Assembly programming is considered as the low level variant as compare to the other programming language. Write an assembly program is crucial at the first stage as it requires the knowledge about its craft. Below are the some essential entities for writing an assembly program:

  • Controls: it tells the assembler about the process of assembly language instructions. It also provides the reserve space for variables and can be specified on the command line.
  • Assembly statements: in assembly programming, statements is not case sensitive. Main statements that take place in the assembly statements are control statement, directives statements and MCU instructions and these statements can be start from the any column.
  • Instructions: it identifies the code of program that is to be assembled by the assembler.
  • Comments: comments are concerned with the text lines that used in the program to define the programs.
  • Symbol: to represent the address, text block, value, we need a name which is known as symbol. Symbol usually refers to a name that we allotted to something. We can also use the symbol to resemble the expressions.
  • Labels: it defines the address in the program. The rules which are applied on the symbol names also applied on the labels. Labels cannot be redefined, it can define only once.
  • Operands: these are specified with the assembler instructions and directives.
  • Immediate data: it is encoded as a part of machine language instruction and refers to a numeric expression.

An assembler does the one to one translation and produces the effective code. It produced the object code which is linked with the linker programs to run on a machine. Advantages of an assembler are as follows:

  • It used various mnemonics. Due to this property, it is easy to use.
  • It is a low level language so its coding is very efficient.
  • It is very fast in speed for translating the assembly language into machine code.

Assembly language comes with its disadvantages too. Few disadvantages of assembler are listed below:

  • It is written for a particular processor or instruction set.
  • Complex assembly code takes a lot of time for performing tasks.
  • It is incompatible with some hardware.

Single target assemblers is a type of assemblers which consists various assemblers viz. 6502 assemblers, ARM assemblers, 680x0 assemblers, Power Architecture assemblers, and many more. It also established a wide range of its products. Some of its products are as follows:

  • VEX Assembler: this product is specially made for the VEX IQ robotics platform.
  • GNU Assembler: it involves the target instruction sets which include ARM architecture, MIPS, PowerPC, and many more.
