11bit ECC SEC DED 普通编码 这里增加了一位校验码p4,DED总是比SEC要多1bit校验码。 原本根据p0~p3可以纠正1bit错误,如果出现2bit的错误,其实校验码也可以检测出有错误,但是既无法纠正,也无法判断出来是2bit错误。DED就是能在错2bit的情况下告知错了2bit。 观察编码,除了增加p4以外,序号的2进制展开多了一行...

In Cypress 65-nm NOR devices, the SECDED ECC scheme has HD=4; therefore, if more than 2-bit errors happen, the ECC scheme will not perform a correction or may perform an incorrect action, depending on the actual errors. However, importantly, in these devices, the ...
我想有两种型号、一种是已停用 ECC、另一种是已激活 ECC。 这也解释了我们需要根据受保护的范围大小独立保留1/9存储器的原因、这只是因为两个布局被修复。 在SDL 库中、我找到了该函数DDRGetTranslatedAddress,我想它将'user-view'地址转换为数据地址或汉明码,如果激活了 SECDED。 使用哪个函数...

By completely utilizing the Hamming distance of the SECDED (128,120) code, 8 ECC bits can potentially correct one error in 120 data bits. Each memory burst is effectively "expanded" from its actual 64 data bits to 120 data bits by "sharing" additional 56 data bits from all of the ...

A key feature of the proposed ECC is that it uses the same number of check bits as the conventional single error correcting/double error detecting (SEC-DED) codes commonly used, and has nearly identical syndrome generator/encoder area and timing overhead. Hence, there is very little additional...
