Nice investigation.
It is always surprising to me when a nice round number like 1MiB results in the “bad performance” configuration (although it happens).
Are you sure erratum is the right word in this context? I usually see it used to describe the notice that a document has an error in it.
- Someone 3d agohttps://en.wikipedia.org/wiki/Erratum#Errata_associated_with_integrated_circuits https://en.wikipedia.org/wiki/Erratum#Errata_associated_with...: “Design errors and mistakes in a microprocessor's hardwired logic may also be documented and described as errata. One well-publicized example is Intel's "FDIV" erratum in early Pentium processors, known as the Pentium FDIV bug. This gave incorrect answers to a floating-point division instruction (FDIV) for a small set of numbers, due to an incorrect lookup table inside the Pentium chip. Similarly, design errors in peripheral devices, such as disk controllers and video display units, can result in abnormal operation under certain conditions.”
- bee_rider 3d agoThe rest of the Wikipedia page discusses errata as the documents issued to describe the errors, not the errors themselves. The section you’ve linked is… a bit weirdly written. I don’t think they meant to suggest an alternative definition there. For example the first sentence could reasonably be read as saying the bugs are being “described as errata” but I think the more likely reading (and the one that is compatible with the rest of the article) is that they were trying to say that the process of documenting and describing the bug is what’s being done “as errata.”
