This provided the impetus for researchers to develop the error detection and correction codes discussed here. Without FEC the world would be quite different.

SEC-DED: Single Error Correction-Double Error Detection codes, which can correct single-bit errors while detecting double-bit errors.

A new technical paper titled “Error Detection and Correction Codes for Safe In-Memory Computations” was published by researchers at Robert Bosch, Forschungszentrum Julich, and Newcastle University.

There are many types of error detection and correction, each with its own decoder, but according to MIT, the algorithm used for the decoder is so complex that it is dedicated to each decoder.

Several techniques can be used to efficiently implement a Hamming coder for single-bit error correction and double-bit error detection.

Finally, similar to the position detection targets (those square bits) in QR codes, Optar uses a two-pixel-wide border around the bit image.

Two other established error-detection techniques are checksum (add up all the bits of the entire message, document or program and produce a single sum) and cyclic redundancy check, which operates ...

This report discusses methods to detect and correct errors automatically, and methods to select records that should preferably be corrected manually (selective and macro-editing).
