SOFTWARE DEVELOPMENT ENVIRONMENT
Modularity, flexibility and methodology are the key
words for the SmartJ™ Development Tools Plat-
form. Using the same interface, the developers are
able to create, compile and debug a project.
The SmartJ™ Integrated Development environ-
ment (IDE) includes:
– A code Generation chain: C/C++ compiler,
assembler and linker. The assembler supports
both native and JavaCard™ instruction sets.
– An instruction set simulator, a cycle accurate
simulator, a C/C++ source level debugger.
Software and Hardware tools allow to
efficiently generate, then validate all code and
application embbeded softwares for the
SmartJ™ platform.
