 We use eclipse and the Java Sun compiler to translate the original source into an intermediate form, which is called bytecode and is stored in class files.  We use eclipse and the Java Sun compiler to translate the original source into an intermediate form, which is called bytecode and is stored in class files. 
 Starting with one or several root classes we translate this classes together with any imported library classes into a single executable target file. The instruction in this target file are native machine instructions.\\ Starting with one or several root classes we translate this classes together with any imported library classes into a single executable target file.

-From the bytecode we start by constructing the control flow graph (CFG). Subsequently a still machine independent intermidiate form is built: the SSA (single static assignment). The CFG and SSA allow for various optimizations and are the base for the register allocation algorith and finally the code generation.+From the bytecode we start by constructing the control flow graph (CFG).

 +==== Different Microarchitectures ====
 +Deep supports the PowerPC and the ARMv7 microarchitectures.
 +The integration of the ARM microarchitecture is still in progress.
 +To distinguish the different architectures in this document, ARM specific information is marked blue and information for the PowerPC architecture is marked orange.
