To cope with the roaring complexity of modern SoC designs, system level modeling and simula- tion are recognized as a must to ful¯ll quick architecture exploration and hardware/software co-veri¯cation. A hy- brid system level modeling method for con¯gurable pro- cessor based on Transport triggered architecture (TTA) is presented in this paper. We implemented a cycle-accurate and bit-accurate model at instruction set simulation level using SystemC to achieve fast simulation and a transaction level model for standard IP interface for easy SoC integra- tion. The object oriented modeling technique was used to cope with the change of the architecture con¯guration. As a case study, an enhanced TTA-like processor, Tcore, was designed and plugged into a SoC for system simulation.
