C Virtual Machine (CVM)

A C virtual machine (CVM) allows applications written in the Java programming language to be portable across different hardware environments and operating systems. The CVM mediates between the application and the underlying platform, converting the application's bytecodes into machine-level code appropriate for the hardware and the ChorusOS operating system. The CVM supports all ChorusOS CPUs and it uses native ChorusOS threads with tunable priority levels. It is possible for several CVMs to run simultaneously.

The ChorusOS CVM offers the following characteristics:

• The CVM and user Java applications can be launched directly from an image, embedded in flash or read-only memory. The CVM also offers Execute-in-Place (XIP) functionality, reducing the size of the footprint of your application.

• A Java Native Interface (JNI).

• The CVM uses a generational garbage collector (GC), and supports the fastest CVM locking mode, using atomic operations.
