Abstract

With the popularity of SoC and improvement in IC design, the functionality of embedded system becomes more complex with shorter time-to-market. Under this circumstance, design space exploration using ASIP (application specific instruction-set processor) and ADL (architecture description language) becomes a natural way. On each cycle of exploration, the application has to be recompiled and executed to obtain the profiling result. Therefore, porting compiler according to the ADL becomes an important issue. Currently, porting an existing compiler by human or using a retargetable compiler are general approaches, but require much human resource or slow down the compiling process. In this thesis, we convert ADL description to a GCC's machine description and discuss some problem and limitation. Finally we propose some suggestion for ADL that we encounter in this thesis.
