Description

一种用于数据纠错ECC译码核主控装置 技术领域
本发明涉及译码核技术领域,具体为一种用于数据纠错ECC译码核主控装置。
背景技术
现行基于迭代运算方式进行数据校验与纠错的主控设计,在进行纠错校验流程时,如果遇到待校验之数据错误比特数量太大,超过或接近译码核处理能力时,译码核可能会发生在迭代运算过程中无法收敛错误情形的状况,或是收敛速度太慢,以至于译码运算在超过迭代次数上限仍然无法顺利校验成功;这样一来不仅会浪费时间进行迭代校验纠错,并且会让队列里预备进行校验的其他错误率较低的数据迟迟无法进行校验.严重拖累整体系统效能。
发明内容
本发明的目的在于提供一种用于数据纠错ECC译码核主控装置,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种用于数据纠错ECC译码核主控装置,包括译码控制单元,所述译码控制单元内设置译码核,所述译码核采集资料/纠错码,并输出状态和资料/纠错码。
优选的,所述译码控制单元内还设置终止管理单元,所述终止管理单元连接译码核。
优选的,包括以下步骤:
A、译码管理器在收到译码核输出状态时,会监控其收敛状况实时比对;
B、监看译码核是否对该笔数据迭代运算有着正确与合理的收敛值,或者比对输出的错误比特数,对照预先设定好的最大容许错误比特数值;
C、若是错误数量没有收敛反而持续发散,以至于在迭代运算后错误比特数持续增加,或者在第一回合迭代运算结束时回报的错误比特数量即超过默认最大容许值时,译码管理器便会停止译码核的迭代运算;
D、同时送出错误通知或者发出中断给CPU.如此一来便可以大幅度减小对于高错误率数据信息的误处理机率。
与现有技术相比,本发明的有益效果是:本发明针对译码核实时监控其输出状态,译码核于每一回合迭代运算结束时输出结果供检查,该结果可以是任何可以代表错误数量级的数字单位或任何表示方式,比如错误比特数或者症状值,能够将高错误率数据讯息交由软件或其他硬件模块或流程进行其他方式的校验与纠错,让原本的正常迭代校验核资源可以继续处理后续的数据校验纠错工作。
