摘要
对于多核DSP应用技术来说,BootLoad技术是一个关键点,也是应用难点之一。针对8核高性能DSP——TMS320C6678的根配置问题进行了研究,包括上电加载过程,单核和多核的emif NOR-FLASH存储器的映像文件的产生,二级加载器的编写和FLASH编程器的构成等。其中,关键是在多核映像文件中,将辅助核的入口地址作为特殊数据来处理,使其他核触发更容易,这也是其他文献未涉及的。该项技术已经用在某图像处理系统中。
The BootLoad technology is a key of multi-core DSP application technology,and one of the difficulties for the application as well.The root configure of 8-core high performance DSP（TMS320C6678）is searched in this paper,including the power-on load process,creation of image files of emif-nor-flash memory for single-and multi-core DSP,compiling of secondary loader and compositions of Fesh programmer.The key point is that the entry address of auxiliary kernel are treated as the special data in multi-core image files to make other slave cores easy to be triggered.It isn＇t mentioned in other refences.The technology has been successfully used in an image processing system.
