Expert subject Free software date March 2011 The Perl virtualmachine is a Stack machine stack based Application virtualmachine process virtualmachine implemented as an opcode s Interpreter computing interpreter which runs previously compiled Perl programs. The opcodes interpreter is a part of the Perl interpreter, which also contains a compiler Lexical analysis lexer , Parsing parser and Compiler optimization optimizer in one executable file, commonly usr bin perl on various Unix like systems or perl.exe on Microsoft Windows systems. Implementation Opcodes The Perl compiler outputs a compiled program into memory as an internal structure which can be represented as a tree graph in which each node represents an opcode. Opcodes are represented internally by typedef s. Each opcode has next other and first sibling pointers, so the opcode tree can be drawn as a basic OP tree starting from root node or as flat OP list in the order they would normally execute from start node. Opcodes tree can be mapped to the source code, so it is possible to Decompiler decompile to high level source code. ref cite web url http perldoc.perl.org B Deparse.html title B Deparse Perl compiler backend to produce ..., require call Perl compiler functions which generate other opcodes in the same Perl virtualmachine ... language and Perl virtualmachine.

Refimprove date December 2009 Virtual DOS machine VDM is Microsoft s technology that allows running legacy DOS and Windows 3.1x 16 bit Windows programs on Intel 80386 or higher computers when there is already another operating system running and controlling the hardware. Overview Virtual DOS machines rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching and forwarding to the normal operating system as Exception handling exception s all operations which involve accessing hardware. The operating system can then perform an emulation and resume the execution of the DOS software. VDMs generally also implement support for running 16 bit 16 and 32 bit protected mode software DOS extender s , which has to conform to the DOS Protected Mode Interface . When a DOS program running inside a VDM needs to access a peripheral, Microsoft Windows Windows will either allow this directly rarely , or will present the DOS program with a Virtual Device Driver which emulates the hardware using operating system functions. A VDM will systematically have emulations for the Intel 8259A interrupt controllers, the Intel 8254 8254 timer chips, the 8237 DMA, etc. NTVDM The NTVDM is present in all 32 bit Windows NT NT based Windows versions.

Java VirtualMachine Tool Interface JVMTI, or more properly, JVM TI was introduced in Java Platform, Standard Edition J2SE 5.0 Tiger . This Interface computer science interface allows a computer program program to inspect the state and to control the execution of applications running in the Java VirtualMachine JVM . JVMTI is designed to provide an Application Programming Interface API for the development of tools that need access to the state of the JVM. Examples for such tools are debugger s or profiler computer science profiler s. The JVMTI is a native interface of the JVM. A library, written in C programming language C or C , is loaded during the initialization of the JVM. The library has access to the JVM state by calling JVMTI and JNI Java Native Interface functions and can register to receive JVMTI events using event handler functions that are called by the JVM when such an event occurs. JVMTI was defined through the Java Community Process by JSR 163. The JVMTI replaces the JVMPI Java VirtualMachine Profiling Interface and the JVMDI Java VirtualMachine Debug Interface . The JVMPI and the JVMDI are declared as being deprecated in J2SE 5.0 and were removed in Java SE6. JVMTI is the lowest level of the Java Platform Debugger Architecture .
