Which of the following is machine independent optimization?
4 Answers. Machine Independent optimization: Loop optimization, Redundancy elimination, folding, Strength reduction, Deadlock elimination.
Which of the following is machine dependent Optimisation?
Explanation: Machine dependent optimizations are: Peephole optimization which includes redundant optimization, strength reduction, flow of control.
What are the different techniques followed in code optimization for independent platform?
For instance, in the case of compile-level optimization, platform-independent techniques are generic techniques (such as loop unrolling, reduction in function calls, memory efficient routines, reduction in conditions, etc.), that impact most CPU architectures in a similar way.
What is machine dependent and machine independent optimization?
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 the 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.
Which of the following is a machine independent phase of the compiler?
Explanation: Machine independent phases are Lexical analysis, Syntax analysis, Semantic analysis, Intermediate code generation and sometime code optimization.
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.
How many types of optimization can be divided?
Explanation: Optimization can be categorized broadly into two types : machine independent and machine dependent.
What is machine independent and dependent?
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.
Which of the following is machine independent?
Answer: A Machine Independent language is one that can run on any machine. An example of this would be Java. Because of the Java Virtual Machine or JVM it can take the compiled code for any given Java App and run it on the machine you are attempting to run it on.
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.
Which of these phases is machine independent?
What is machine independent optimization?
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 various optimization techniques?
Optimization of financial portfolios. Performing the least-squares method of regression. Controlling scheduling in chemical plants. Solving more complex non-linear programming problems.
Which language is machine independent?
Third Generation (3GL) – high level language. It is machine independent which means it can run on any computer. Before the computer can understand execute it, the program has to be converted to machine language.
What are the different types of top-down parsing techniques?
Classification of Top-Down Parsing –
- Recursive Descent Parsing.
- Predictive Parsing or Non-Recursive Parsing or LL(1) Parsing or Table Driver Parsing.
