Parrot assembly language (PASM) is the low level language that compiles down to bytecode. PASM code is usually stored in files with the filename extension ".pasm". Parrot intermediate representation (PIR [15]) is a slightly higher level language than PASM and also compiles down to bytecode. It is the primary target of language implementations.
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 ...
Rather than implement the execution of code by virtue of a large switch statement containing every possible bytecode, while operating on a software stack or a tree walk, a template interpreter maintains a large array of bytecode (or any efficient intermediate representation) mapped directly to corresponding native machine instructions that can ...
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 ...
YARV (Yet another Ruby VM) is a bytecode interpreter that was developed for the Ruby programming language by Koichi Sasada.The goal of the project was to greatly reduce the execution time of Ruby programs.
Java bytecode is used at runtime either interpreted by a JVM or compiled to machine code via just-in-time (JIT) compilation and run as a native application. As Java bytecode is designed for a cross-platform compatibility and security, a Java bytecode application tends to run consistently across various hardware and software configurations. [3]
During compilation of CLI programming languages, the source code is translated into CIL code rather than into platform- or processor-specific object code.CIL is a CPU- and platform-independent instruction set that can be executed in any environment supporting the Common Language Infrastructure, such as the .NET runtime on Windows, or the cross-platform Mono runtime.
The Jazelle instruction set is well documented as Java bytecode.However, ARM has not released details on the exact execution environment details; the documentation provided with Sun's HotSpot Java Virtual Machine goes as far as to state: "For the avoidance of doubt, distribution of products containing software code to exercise the BXJ instruction and enable the use of the ARM Jazelle ...
