Examples of CPUs include those made by Intel e. Compilers Compilers convert high-level language code to machine object code in one session. Compilers can take a while, because they have to translate high-level code to lower-level machine language all at once and then save the executable object code to memory. 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. A cross-compiler, however, can generate code for a platform other than the one it runs on itself.
A cross-compiler running on a Windows machine, for instance, could generate code that runs on a specific Windows operating system or a Linux operating system platform. Source-to-source compilers translate one program, or code, to another of a different language e. Choosing a compiler then, means that first you need to know the ISA, operating system, and the programming language that you plan to use.
Compilers often come as a package with other tools, and each processor manufacturer will have at least one compiler or a package of software development tools that includes a compiler. Often the software tools including compiler are free; after all, a CPU is completely useless without software to run on it. Assembly language helps programmers to write human-readable code that is almost similar to machine language. Machine language is difficult to understand and read as it is just a series of numbers.
Assembly language helps in providing full control of what tasks a computer is performing. The learning of assembly language is still important for programmers. It helps in taking complete control over the system and its resources. By learning assembly language, the programmer can write the code to access registers and retrieve the memory address of pointers and values. It mainly helps in speed optimization that increases efficiency and performance.
Assembly language learning helps in understanding the processor and memory functions. If the programmer is writing any program that needs to be a compiler, that means the programmer should have a complete understanding of the processor. Assembly language helps in understanding the work of processors and memory.
It is cryptic and symbolic language. Assembly Language helps in contacting the hardware directly. This language is mainly based on computer architecture, and it recognizes a certain type of processor and its different for different CPUs.
Assembly language refers to transparency compared to other high-level languages. It has a small number of operations, but it is helpful in understanding the algorithms and other flow of controls. It makes the code less complex and easy debugging as well. Most programs are written in high level languages or assembly language. These programs are easy to read and understand by programmers but not understandable by the computer.
The computer only understands machine language. It consists of binary which is ones and zeros. Therefore, the high level or assembly program should be converted into machine language for the computer to understand the instructions. Compiler, interpreter and assembler are translators that convert high level or assembly language based programs to machine language. What is Compiler — Definition, Functionality 2. What is Interpreter — Definition, Functionality 3. What is Assembler — Definition, Functionality 4.
A compiler is a language translator that converts high level programs into machine understandable machine codes. In this process, the compiler converts the whole program to machine code at a time. If there are any syntactic or semantic error, the compiler will indicate them.
It checks the whole program and displays all errors.
