系统芯片集成的软硬件协同设计方法研究

Based on the investigation of representations of algorithm, program on the top system level and the relation to their architecture on chip and their design and synthesis methodology, we established an virtual embedded CPU machine based hardware/software codesign platform. With the application target to the design of media video and audio decoder and digital transmission chip, the real time operating system for the platform and SoC, the retargetable compiler for the target machine, the data transfer bus and its management are investigated for their partition and verification methodology by hardware /software codesign, and prototype of CPU and DSP soft core have been written in this purpose. The theoretical result and hardware software codesign platform have already been applied in DSP core study in 863 project, compiler for industry 16 bit DSP and media video/audio decoder and digital transmission chip design.
