摘要
基于DSP的系统设计中,由于部分DSP内部无非易失性存储器,为了保证该系统设计掉电时程序不丢失,因此必须外部扩展ROM或Flash用于存储数据。以TMS320C6713型浮点DSP和AM29LV800B型Flash存储器为例,阐述了上电自举的硬件设计,JTAG程序加载,上电自举过程,Flash的擦除及烧写,链接命令文件和编写,并详细说明各部分相互联系及作用。
In the system based on DSP, because of no nonvolatile memory in some DSP,we must use external extended ROM or Flash to store data.The hardware design of bootload, JTAG programme loading, bootload processing, Flash eraseing and programming, link file and its programming are explained. The relationship between those parts is also explained in detail.
