| Abstract: | A kind of high speed data collection and transmission system is designed in which TMS320VC5502 DSP acts as the core processor in this paper.ADC chip is connected with MCBSP based on SPI,which makes the best of the DSP resource;in addition,DMA controller is used to control data-collection,which enables DMA and CPU to work at the same time.Then the data handled by DSP is conveyed to PC through USB interface and it can transfer mass data quickly.The experiment results show that this system has the advantages of high-performance,low consumption and so on,therefore,it has higher practical utility in industry fields. |
