| 摘 要： | 在液晶电视的嵌入武系统中,系统参数通常存放在主板芯片E2 PROM里,由于外界脉冲或其TA原因会使E2 PROM中的数据发生丢失或错误,从而导致液晶电视偏色或无法正常启动.为解决此问题,提出一种利用CRC检错码和RS纠错码的机制来实现对系统参数的备份,即使数据发生部分错误也能够即时纠正过来.同时,为了检验基于检错和纠错数据备份机制的可靠性,设计了一套能够针对液晶电视主板上E2 PROM芯片中数据的正确性进行测试的工具,在一线工厂应用价值较高.

| Abstract: | In LCD TV embedded system, system parameters usually are stored on mainboard EEPROM IC.Because of pulse from outside or other reasons, The system parameters might be loss or error, then LCD TV display colour deviation or even can not normally boot up because of this reason.In order to solve this issues, this article raise a new system parameters backup mechanism which use CRC error detection codes and RS error correction codes .Even the partial data loss ,this mechanism can correct it. Meanwhile, in order to check this data backup mechanism"s reliability, it needs to design a tooling which can verify these data which are stored in the EEPROM. It is valuable for application of the factory. |
