JC Virtual Machine - Converts Java to C

  •        8407

JC Virtual machine converts Java class files to C source code. It uses SOOT Java Bytecode analysis framework to convert the Java files to C. It could also compiles with GCC and loads them with built-in ELF loader. Additional to that, JC provides a complete Java runtime with optimization to increase performance.

JC optimizes the code at code generation time which increases its runtime performance. It does have good interpreter but most of the jobs are done at the code generation time. When combined with the proven power of GCC's C optimizer the results are impressive.

Additional to C conversion and Java runtime, It has thread support based on the POSIX pthread(3). Support for JNI, Reflection and Java 2 style loader support is also available. It uses GNU Classpath to provide java runtime.

Erjang is a virtual machine for Erlang, which runs on Java 7.It loads Erlang's binary .beam file format, compiles it into Java's .class file format, and loads it into the JVM. It will eventually have it's own implementation of all Erlang's BIFs (built-in-functions) written in Java.

PH7 - An Embedded Implementation of PHP (C Library)

PH7 is a in-process software C library which implements a highly-efficient embeddable bytecode compiler and a virtual machine for the PHP programming language. In other words, PH7 is a PHP engine which allow the host application to compile and execute PHP scripts in-process. PH7 is to PHP what SQLite is to SQL. As an embedded interpreter, it allows multiple interpreter states to coexist in the same program, without any interference between them. Programmatically, foreign functions in C/C++ can be added and values can be defined in the PHP environment. Being a quite small program, it is easy to comprehend, get to grips with, and use.
