Qt中调用DSP库实现双核异构通信

Dual Heterogeneous Communication Implementation Based Calling the DSP Database in Qt

在物联网和大数据飞速发展的时代,大部分的数据在采集后都须放到PC机或服务器上处理,这使得工作效率和便捷性都受到影响,同时也制约着技术的发展,如何才能在终端嵌入式设备上也能分析处理复杂的数据,这是我们研究的方向。本文研究基于ARM/DSP双核CPU的通信方法,这使得DSP极快的数据处理能力和ARM天生的终端控制能力完美结合,实验采用TI公司基于DM3730双核CPU的devkit8500评估板和该公司研发的集成开发工具DVSDK做测试,通过ARM控制端的Qt程序来调用DSP端封装好的库函数;通过测试表明,这种双核通信方式具有良好的稳定性,处理数据的及时性和准确性,以及实用性。

In the Intemet of things and the big data era of rapid development, most ofthedata are to be placed on the processing of PC machine and the server in a coUection, whi-ch makes the work efficiency and convenience be affected, but also restrict the developmentoftechnology. How to embedded devices in our terminal also can deal with complex dataanalysis, which is our research direction. Study on the method of ARM/DSP communicationbased on dual core CPU, which makes DSP very fast data processing ability of ARM andthecombination of natural terminal control abihty and perfect, the experiment uses the devkit-8500 evaluation of DM3730 dual core CPU board and the company sintegrated developmenttool based onDVSDK of TI company to do the test, Qt programs call library functions ofl）SP of be encapsulated by the ARM control terminal. The test shows that this dualcore co-mmunication mode has good stability, the ti-meliness and accuracy of processing data, as w-ell as practical.
