As an effective method for MPSoC development,we present a gradual refinement flow starting from a high-level Simulink model to a synthesizable and executable hardware and software specification. The proposed methodology consists of five different abstract levels:Simulink combined algorithm and architecture model(CAAM),virtual architecture(VA),transactional accurate architecture(TA),virtual prototype(VP) and field-programmable gate array(FPGA) emulation. Experimental results of Motion-JPEG and H.264 show that the proposed gradual refinement flow can generate various MPSoC architectures from an original Simulink model,allowing processor,communication and tasks design space exploration.展开更多
