Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...
A source-to-source translator, source-to-source compiler (S2S compiler), transcompiler, or transpiler [1] [2] [3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.
Bytecode is a portable low-level code similar to machine code, though it is generally executed on a virtual machine instead of a physical machine. [4] To improve their efficiencies, many programming languages such as Java , [ 4 ] Python , [ 5 ] and C# [ 6 ] are compiled to bytecode before being interpreted.
In a bytecode-compiled system, source code is translated to an intermediate representation known as bytecode. Bytecode is not the machine code for any particular computer, and may be portable among computer architectures. The bytecode may then be interpreted by, or run on a virtual machine. The JIT compiler reads the bytecodes in many sections ...
During the software development cycle, programmers make frequent changes to source code. When using a compiler, each time a change is made to the source code, they must wait for the compiler to translate the altered source files and link all of the binary code files together before the program can be executed. The larger the program, the longer ...
The software development process is noticeably different depending on the type of translator used by a developer, this of course differs from translator to translator. Stages of the development process that are influenced by a translator include the initial programming stage, the debugging stage, and most notably the execution process.
A bytecode interpreter executes the bytecode, but the JIT compiler will translate the bytecode to machine code when increased performance is necessary. [ 60 ] [ non-primary source needed ] Hardware compilers (also known as synthesis tools) are compilers whose input is a hardware description language and whose output is a description, in the ...
Further there are and have been several indirect users of the Translate Toolkit API: Pootle - an online translation tool; open-tran - providing translation memory lookup (was shut down on January 31, 2014.) [3] Wordforge (old name Pootling) - an offline translation tool for Windows and Linux; Rosetta - free translation web service offered by ...
