This is probably a rule I believed in as a beginner, and completely don't believe in anymore today.
Lets take a look at an exceptionally well designed system: single-error correction double-error detection codes. Also known as "ECC RAM". The implementation of this only works for *exactly* 64 bits + 8-parity bits.
Now sure, we can talk about how we can generalize SECED ECC to different numbers of bits or whatever. But I'll also point out that the only implementation in widespread use is ECC Memory, the 64-bits + 8-parity bits (72-bits total) implementation.
- alex_sf 4y agoI would argue your example is a special case of only allowing one.
- dragontamer 4y agoBut it detects two-bit errors. Which is nonzero, non-one, and non-infinity. -------- SEC without DED is the classic implementation of Hamming error correction codes. The double error detection (aka DED) but is grafted on top of the theory, because it's useful in practice.
- Nullabillity 4y agoIt is generalized, you can chain together infinitely many blocks.
