摘　　要：随着卫星技术的发展,卫星载荷的功能越来越强大,CPU作为载荷的处理核心部件,其实现的业务功能也在不断扩充。通常地面站需要对CPU程序进行升级重构时,采用远程上注的方法,因此一种可靠性高且效率高的上注流程就很重要。文章提出了一种基于BM3823的CPU程序上注和重构技术及实现方法,经过验证,可以高效运行。With the development of satellite technology,the function of satellite payload is becoming more and more powerful.As the core component of payload processing,the business functions realized by CPU are also expanding.Generally,when the ground station needs to upgrade and reconstruct the CPU program,it adopts the method of remote upload,so a reliable and efficient upload and rebuild process is very important.This paper shows a mechanism and implementation of remote upload and reconstruction of CPU programs on the satellite.
