| - | * Crosscompiler (to translate Java bytecode into machine code, "Java on the metal" | ||
| - | * Eclipse plugin (for the integration into Eclipse) | ||
| - | * Runtime System (operating system, device drivers and system libraries for the target) | ||
| - | |||
| - | ===== Overview ===== | ||
| - | deep has a modular design and can be integrated into different development frameworks. Currently deep can be run standalone or can be used in eclipse as a plugin. deep produces code for PowerPC processors. We support hardware plattforms with the mpc555 and mpc5200 processors. | ||

| - | ==== Translation of bytecode into machine code ==== | ||
| - | 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.\\ | ||
| - | 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. | ||
