What are the machine dependent assembler features?
PC-relative or Base-relative addressing: op m.
What is assembler dependent on?
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 are the features of assembly language?
The features of the assembly language are mentioned below:
- It can use mnemonic than numeric operation code, and it also provides the information of any error in the code.
- This language helps in specifying the symbolic operand that means it does not need to specify the machine address of that operand.
What is assembler in microcontroller?
An assembler is a program that translates symbolic code (assembly language) into executable object code. This object code can be executed with a 80C51-compatible microcontroller. An assembly program has three parts: Machine instructions – Code the machine can execute.
Is assembler machine-dependent?
And assemblers translate programs written in low-level or assembly language into machine code. Assembly language is machine-dependent, yet mnemonics used to represent instructions in it are not directly understandable by machine and high-Level language is machine-independent.
What is machine-dependent compiler?
Machine-dependent optimization is done after the target code has been generated and when the code is transformed according to the target machine architecture. It involves CPU registers and may have absolute memory references rather than relative references.
Are assemblers machine dependent?
Assembly language is machine-dependent, yet mnemonics used to represent instructions in it are not directly understandable by machine and high-Level language is machine-independent. A computer understands instructions in machine code, i.e. in the form of 0s and 1s.
Is machine language machine dependent?
Machine language is a first generation language written using 1s and 0s. It is a low level language that is machine dependent. This means it can only work on the computer it was designed for.
What are the features of machine language and assembly language?
Machine languages comprise of binary digits 0s and 1s. Assembly languages have a syntax that is similar to the English language; therefore, they can be understood by programmers and users alike. Machine languages are platform-dependent, and their features vary accordingly.
What is computer machine language?
Machine language is the language understood by a computer. Machine language is made up of instructions and data that are all binary numbers. Machine language is normally displayed in hexadecimal form so that it is a little bit easier to read.
Is assembler machine dependent?
What is a computer assembler?
An assembler is a program that takes basic computer instructions and converts them into a pattern of bits that the computer’s processor can use to perform its basic operations. Some people call these instructions assembler language and others use the term assembly language.
