What is machine dependent and independent?
Machine-dependent software is software that runs only on a specific computer. Applications that run on multiple computer architectures are called machine-independent, or cross-platform.
What is machine dependent in compiler design?
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.
What is machine independent compiler?
Machine Independent code optimization tries to make the intermediate code more efficient by transforming a section of code that doesn’t involve hardware components like CPU registers or any absolute memory location.
What are the features of a compiler?
Features of a Compiler
- Compilation speed.
- The correctness of machine code.
- The meaning of code should not change.
- Speed of machine code.
- Good error detection.
- Checking the code correctly according to grammar.
What is machine independent?
machine-independent A term applied to software that is not dependent on the properties of a particular machine, and can therefore be used on any machine. Such software is also described as portable. A Dictionary of Computing.
Are compilers machine dependent?
A compiler creates machine code that runs on a processor with a specific Instruction Set Architecture (ISA), which is processor-dependent. For example, you cannot compile code for an x86 and run it on a MIPS architecture without a special compiler. Compilers are also platform-dependent.
What is machine dependent language?
Machine languages are so closely related to the structure of a particular computer that they are said to be machine dependent. Programs written in machine language are not portable, that is, they may not be run on other computers with different machine languages.
What is difference between machine independent and platform independent?
A program that run at any OS means, that is called platform independent and those programs run at any architecture of computer (hardware) are called machine independent and the phenomenon is platform and machine independency.
What is the common feature of compiler and interpreter?
Difference between Compiler and Interpreter –
| Compiler | Interpreter |
|---|---|
| A compiler is a program that converts the entire source code of a programming language into executable machine code for a CPU. | An interpreter takes a source program and runs it line by line, translating each line as it comes to it |
What are the different types of compiler?
Broadly, there are three types of Compilers: Single Pass Compilers. Two Pass Compilers. Multi pass Compilers.
What are the difference between machine dependent and independent optimization?
Machine dependent code optimization is applied to object code. Machine-independent code optimization is applied to intermediate code. Machine dependent optimization involves CPU registers and absolute memory references. Machine independent code optimization does not involve CPU registers or absolute memory references.
What is machine dependent?
Refers to a software application that runs only on a particular type of computer. Programs that run on a variety of different types of computers are called machine independent.
What are the features of machine language?
Machine language, or machine code, is a low-level language comprised of binary digits (ones and zeros). High-level languages, such as Swift and C++ must be compiled into machine language before the code is run on a computer. This binary data, or machine code, is processed as input by the CPU.
What is a machine-independent language?
High level language is machine independence program. A high-level language (HLL) is a programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer.
What is platform dependent example?
Platform dependent typically refers to applications that run under only one operating system in one series of computers (one operating environment); for example, Windows running on x86 hardware or Solaris running on SPARC hardware.
What is meant by platform dependent and platform independent?
Sometimes, it means the same as “hardware dependent” or “machine dependent” and refers to applications that run in only one hardware series with the operating system not being relevant.In contrast, “platform independent” means that the application can run in different operating environments.
What is the main difference between compiler and interpreter?
Interpreter translates just one statement of the program at a time into machine code. Compiler scans the entire program and translates the whole of it into machine code at once. An interpreter takes very less time to analyze the source code. However, the overall time to execute the process is much slower.
What are the major differences between compiler and interpreter?
Interpreter Vs Compiler
| Interpreter | Compiler |
|---|---|
| No Object Code is generated, hence are memory efficient. | Generates Object Code which further requires linking, hence requires more memory. |
| Programming languages like JavaScript, Python, Ruby use interpreters. | Programming languages like C, C++, Java use compilers. |
What is compiler and different types of compiler?
A compiler is a computer program that changes source code written in a high-level language into low-level machine language. It translates the code written in one programming language to some other language without modifying the definition of the code.
How many types of compiler are there explain in detail?
Compilers are divided into three parts 1) Single Pass Compilers 2)Two Pass Compilers, and 3) Multipass Compilers.
What is machine dependent and machine independent code optimization?
In machine dependent code optimization, optimization is applied to the source code. Allocating sufficient amount of resources can improve the execution of the program in this optimization. What is Machine Independent Code Optimization? When optimization is done on the intermediate code, it is called the machine independent code optimization.
How does the compiler modify the intermediate code?
After generating intermediate code, the compiler can modify the intermediate code by address calculations and improving loops. While producing the target machine code, the compiler can make use of memory hierarchy and CPU registers. Optimization can be categorized broadly into two types : machine independent and machine dependent.
What is the role of compiler in code optimization?
Therefore, a compiler is used to convert those instructions into machine code or target code. It goes through several phases to build the target code. Code optimization is one of them. There are two optimization techniques like, machine dependent and machine independent code optimization.
Why are the codes of elementary level languages machine dependent?
Read the introduction of compilers for high-level language. The codes are machine dependent in the case of elementary level. It is because of the requirement of the instruction set for the generation of the code of a computer. There are several problems and issues related to this.
