随着技术进步,DSP在线升级效果得到了优化,现实中为完整解决DSP在线升级固有的技术问题,降低技术升级失败的概率,合理保障在线升级完美的实现,需巧借串口通信协议,对现有的在线升级技术进行更新,以保障软件应用的稳定性。文章在原有方案基础上设计了基于CAN串口通信的高效率升级优化措施,并描述了新软件的逻辑分配原则及软硬件设计相关内容,借助科学设计的思路对启动执行流程进行了完善,完善期间加入了应答式通信以及高精准度的校验模块功能,以保障系统应用的合理性。结合检测结果可知,基于串口通信的DSP若要实现在线升级,满足小型化设计需求,则需应用优质的CAN串口通信外接方案。具体来讲,这种合理的升级改造方案,无限拓宽了DSP的应用范畴,值得深度研究与推广。同时,基于串口通信的DSP在线升级研究成果,可提供有益的参考。

With the advancement of technology,the effect of DSP online upgrade has been optimized.In reality,in order to solve the inherent technical problems of DSP online upgrade completely,reduce the probability of failure of technical upgrade,and reasonably ensure the perfect realization of online upgrade,it is necessary to use serial com munication protocols.The existing online upgrade technology is updated to ensure the stability of software applications.On the basis of the original scheme,this paper designs high-efficiency upgrade optimization measures based on CAN serial communication,and describes the logic allocation principle of the new software and the related content of software and hardware design.During the improvement period,responsive com munication and high-precision verification module functions were added to ensure the rationality of system application.Combined with the test results,it can be seen that if the DSP based on serial communication wants to realize online upgrade and meet the needs of miniaturized design,it needs to apply a high-quality CAN serial communication external solution.Specifically,this reasonable upgrade scheme widens the application scope of DSP infinitely,and is worthy of in-depth research and promotion.At the same time,the research results of online upgrade of DSP based on serial communication can provide useful reference.
