- redis_mlc 6y agoCan you expand the pronoun "it" so your comment is less ambiguous? Thanks.
- fulafel 6y agoECC ("it") doesn't need to be implemented in both CPU and RAM.
- manfredo 6y agoInteresting, so validation of the parity bits occurs in the CPU? Presumably when data is read off the bus.
- wmf 6y agoIntel calls this in-band ECC and it's in their Elkhart Lake Atom SoC. https://www.anandtech.com/show/16102/intel-launches-10nm-atom-embedded-cpus-elkhart-lake-now-available https://www.anandtech.com/show/16102/intel-launches-10nm-ato... This is pretty inefficient compared to regular ECC but you can't really do regular ECC with LPDDR4. Nvidia also implemented something similar years ago.
- fulafel 6y agoInteresting. Nvidia indeed mentions this at https://developer.nvidia.com/blog/inside-pascal/ https://developer.nvidia.com/blog/inside-pascal/
