一种按需加载的DSP程序扩容方法

DSP Program Expansion Method Based on Demand Loading

随着软件无线电的发展,软件无线电平台的处理能力越来越强大、平台上实现的功能越来越多,平台的硬件结构也多种多样,各平台之间无法实现软硬件资源的共享,在实现通用数字中频的工作中,DSP程序的扩容需求逐步增大。针对上述问题,本文提供一种按需加载的DSP程序扩容方法,这种方法可以根据需要加载不同的DSP函数,相当于对DSP的内存进行了扩容。这种方法减少了加载时间,并且不必保证DSP程序的运行速度。本方法适用于TI公司、ADI公司以及目前国产化DSP,型号不限于TMS320C6713、TMS320C6416、TMS320C6455、TMS320C6678等。

Along with the development of software radio,the processing capacity of software radio platform is becoming more and more powerful,the functions realized on the platform are more and more,the hardware structure of the platform is also varied,and the sharing of hardware and software resources can not be realized the platforms.To solve the above problems,this paper provides an on-demand loading DSP program expansion method,which can load different DSP functions according to the need,which is equivalent to the expansion of DSP memory.This method reduces the loading time and does not have to guarantee the running speed of the DSP program.This method is applicable to TI companies,ADI companies and current domestic DSP,models are not limited to TMS320C6713,TMS320C6416,TMS320C6455 and TMS320C6678.
