给出了一种支持软件远程重载的无线通信终端设计方案。首先讨论了系统的整体设计思路;然后给出了无线通信终端的硬件设计方案,提出了一个支持利用软件进行系统功能重构的通用硬件平台,并分析了软件重新载入的机制。最后为了保证利用无线方式可靠地进行软件重载,设计了一套支持软件重载的三层通信协议。
A design scheme of wireless communication terminal supporting software remote overloading is given. First, the overall design concept of the system is discussed. Then, the hardware design of the wireless communication terminal is given. A general hardware platform that supports software system reconfiguration is proposed. The mechanism of software reloading is analyzed. Finally, in order to ensure the reliable use of wireless software overloading, designed to support a software overloading three-tier communication protocol.
