基于SST微控制器的MSAP系统在线升级方案的设计
Design of MSAP Online-upgrade System Based on SST MCU
【摘要】 MSAP(多业务接入平台)中业务子卡的常用处理器是MCU,应用程序一般是通过现场编程下载到MCU的片内存储器中,这种方式不便于软件的实时升级和维护。本文研究了内嵌IAP功能的嵌入式微控制器SST89E516RD2,利用微控制器片外扩展的Flash的存储空间,成功地实现了远程在线升级。
【Abstract】 The mainly processer of service card in MSAP system is MCU,the application program is commonly downloaded to internal memory in site.This way is very inconvenient to be real-time upgraded and maintenance.This paper discussed the IAP function of SST89E516RD2,distributed the memory of external Flash effectively.On the basis of these results,this design implements remote upgrade of application program successfully.
