Java Language Cross Compiler Meets Runtime Requirements

FastJ is a Java language cross compiler said to be the first tool of its kind to meet the demanding runtime performance and compact code-size requirements of embedded system developers. Unlike conventional Java compilers, FastJ does not generate Java byte code for execution on a Java virtual machine. Instead, in a manner similar to C/C++ cross compilers, the tool compiles programs written in Java directly to machine code for several popular 32-bit processors. This approach bypasses the need for an intermediate Java runtime interpreter and allows programs written in Java to execute directly on the target CPU. In addition, FastJ can compile Java byte code directly to machine code.An important advantage of FastJ is user-configurable garbage collection techniques that optimize runtime performance. A runtime error checker backstops this capability by detecting memory management problems.
