【Abstract】 The High-Speed Communication Techniques between PC computer and DSP controller, between Profibus and Automobile’s ECU, and between DSP controller and DSP controller are discussed. First, the rules of achieving series- parallel converting and High-Speed USB communication by using CY7C63101 A, achieving Profibus-DP intelligentization slave station by using SPC3, achieving communicating between DSP and DSP via SPI are discussed. Further, the design scheme of software and hardware of communication sub-system is probed. The application effect is good in the car-engine integrated controlling system designed by writer.更多还原
