The Design And Implementation Of The Double Channels Audio Signal Systemman-machine Interface And Dual-core Communication

One of the important reasons for the water resources waste is caused by city groundwater pipeline leak, as freshwater resource exhausting, people are paying more and more attention to the pipe leakage detection.The voice signal to leak leakage detection collection and analysis is the most effective methods, many of the relevant units are in the aspects of the positive research, also developed many instruments which have feat ures. But on the current market, most of the nstruments are based on DSP chip TMS320C5000, This chip can't support the current mainstream color LCD and touch screen man-machine interface, which not only limits the function expansion upgrade, but also makes the instrument in large size, lack of modern industrial design times, do not accord with embedded electronic equipment miniaturized, portable turn of development trend.Based on the above reasons, this paper based on DSP chip TMS320C5416, and added the microprocessor LPC2387, color LCD and touch screen, realize the man-machine interface to the current mainstream control with dual-core system By which we can give full play to the strengths of the two processors. the TMS320C5416 high-performance digital signal processor can complete the audio signal, real-time processing of executive computation-intensive operation, combined with the LPC2387 microprocessor's powerful control ability and rich interface function, we can give full play to the strengths of the two processors through the communications between ARM micro controller and DSP chip.In that case, the whole system can work in greatly increased efficience.man-machine interactive, small volume, low power consumption, easy to system function expansion to upgrade. This paper descripts and carried on the detailed description the LPC2387 microprocessor, touch screen and color LCD composition system man-machine interface design mainly from two aspects of hardware and software. Also on LPC2387 microprocessors and TMS320C5416 chip the hardware realization dual-core communication between structure and communication both drivers details and a theoretical discussion.
