Computers employ a variety of schemes to check whether a chunk of digital information–transmitted as a message, stored in a database, or functioning as a set of instructions–remains error-free. Such ...

Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...

I’ll discuss them with respect to RS code but they can be used with all FEC codes, including mixing types of FEC code. Interleaving is simply taking a number of messages and mixing the bytes, in a ...

Error Correction Codes (ECC) play an essential role in safeguarding memory systems by detecting and correcting errors that arise from various sources, including ...

IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum ...

A preprint study by Quantiniuum claims a new error-detecting code was able to accurately simulate a hydrogen molecule and could help create more advanced quantum computers. A team of scientists claim ...

Scientists have for the first time demonstrated improvement in quantum computers by using codes designed to detect and discard errors in the logic gates of such machines. The codes were applied to IBM ...

The controller has to do two sets of writes or reads — one for the data and one for the code, adding latency to each access. Some controllers can pack multiple codes together for sequential data, ...

As with any electronic system, errors in the memory subsystem are possible due to design failures/defects or electrical noise in any one of the components. These errors are classified as either ...
