In general, interpreters and compilers can both be used to translate machine language. An interpreter will commonly perform tasks such as Parsing, type checking and lexing, and does the same kind of work as a compiler. Interpreters have a fast startup time, don't have to go through a compi...
, essentially doing a compiler's job for every execution. That's a lot of overhead, so in reality, most interpreters like the V8 JavaScript engine, the Java Virtual Machine (JVM), and .NET's Common Language Runtime make use of Just-In-Time compilation to speed up the interpreter....

Just-in-time CompilerDalvik virtual machine is the main process to execute programs for Android. A executable program is compiled into DEX format from JAVA code. In addition, the analysis and execution of bytecode instruction in DEX file are dominated by the interpreter in Dalvik virtual machine...
、后端编译/即时(JIT)编译 通过Java虚拟机(JVM)内置的即时编译器(Just In Time Compiler,JIT编译器);在运行时把Class文件字节码编译成本地机器码的过程; 优点: 通过在运行时收集监控信息,把"热点代码"(Hot Spot Code)编译成与本地平台相关的机器码,并进行各种层次的优化; 可以大大提高执行效率; 缺点: 收集监控...

PyPy JIT Compiler: PyPy is a fast, compliant, and highly compatible alternative to the standard CPython interpreter. It utilizes a Just-in-Time compiler to improve performance. PyPy analyzes the Python bytecode and translates it into machine code on the fly. This process eliminates much of the...
compiler at runtime. Another approach, used by the Java runtime and called HotSpot, combines an interpreter and a JIT compiler, invoking the JIT compiler only for sequences of code that are used often, and using the interpreter for bytecode that is used only rarely. Another approach used ...
Java source files are compiled by the Java compiler into platform independent bytecode or Java class files. After your fire your Java application, the JVM loads the compiled classes at run time and execute the proper computation semantic via the Java interpreter. ...
The 17 instructions generated by the compiler compare favorably with the 100+ instructions that the interpreter would execute for the same code snippet, including 4 indirect jumps. i=2. This is the first iteration of the outer loop. The loop on lines 4-5 becomes hot on its second iteration...
