【摘要】：首先簡(jiǎn)要介紹了LTE-A手機(jī)終端的系統(tǒng)結(jié)構(gòu),在此基礎(chǔ)上為解決LTE-A手機(jī)程序跑飛需要拔電池重啟的問題,提出了基于分立器件實(shí)現(xiàn)看門狗復(fù)位的設(shè)計(jì)方案,結(jié)合基帶處理器的通用輸入輸出接口進(jìn)行軟件控制,能夠輸出滿足系統(tǒng)供自動(dòng)重啟需要的復(fù)位時(shí)間,并對(duì)硬件進(jìn)行了系統(tǒng)的測(cè)試,該看門狗電路具有較高的時(shí)效性和可靠性,有助于提高LTE-A手機(jī)系統(tǒng)的穩(wěn)定性。
[Abstract]:Firstly, the system structure of LTE-A mobile phone terminal is briefly introduced. In order to solve the problem that the LTE-A mobile phone program needs to be restarted by unplugging the battery, a design scheme based on discrete devices to realize the watchdog reset is put forward. Combined with the general input and output interface of the baseband processor to control the software, the reset time that meets the need of automatic restart of the system can be outputted. The hardware is tested systematically. The watchdog circuit has high timeliness and reliability. It is helpful to improve the stability of LTE-A mobile phone system.
