Research On The DSP Based Multi-channel Synchronous Data Acquisition And Hard Disk Storage Technology

Based on the detailed investigation into the multi-channel synchronous data acquisition and hard disk storage technology, a DSP-based system of eight channelsynchronous data acquisition and hard disk storage has been designed in this thesis. The design ideas of the whole system and the design methods of the hardware and software of the system, together with the structure and function of the main components, have been discussed in detail. The design of hardware circuit has been completed and the debugging result of the single channel data acquisition module has been given. The system takes TMS320VC5509 as a core processor, with its embedded USB interface completing the data transmission and the Complex Programmable Logic Device-CPLD implementing the logic control of the peripherals of the DSP. The system has wide application foreground in the fields of industrial control, communication and electronic system, and signal detection and processing.
