As a non-contact measurement of optic-electro on a single spot,its advantages are high measurement speed,high precision,great anti-jamming,small measurement spot,easy operation,wide application range and so on. Laser triangulation measurement based on PSD makes system perfect with small volume,high sensitivity,low noise,high resolution. The system’s precision is above 0.5%. It shows that with simpler specified PSD software it can be found a convenient way to optimize system design,improve reliability,shrink volume,reduce power and shorten exploitation period.展开更多

Three main constraints of embedded systems design process are investigated: the complexity, the partitioning between hardware and software aspects and the reusability. Two intermediate models are carried out in order to solve the complexity problem. The partitioning problem deals with the proposed hardware/software partitioning algorithm based on Ant Colony Optimisation. The reusability problem is resolved by synthesis of intellectual property blocks. Specification and integration of an intelligent controller on heterogeneous platform are considered to illustrate the proposed approach.展开更多
