The RAM in our computers is constantly refreshed to ensure that it maintains the intended information. For most of us, however, a bit flipped somewhere in the memory of our cell phones or laptops is ...

An error detection technique that tests the integrity of digital data in the computer. Parity checking adds an extra parity cell to each 8-bit byte of memory, thus ...

Should designers worry about soft errors in embedded designs? With the prevalence of higher memory densities and finer process geometries, many design teams are now evaluating techniques to alleviate ...

The use of parity bits is a common method of detecting errors in data transmission and storage. Before looking at the use of parity bits in RAID, let's look more ...

Not using a parity bit to check for errors. For example, an 8-N-1 setting in a communications program, which was widely used before the Web, means each character transmitted contains (8) eight bits, ...

Calculating an LDPC Note: the 3rd parity bit should be 0, not 1 LDPCs append a series of parity bits to a message. Usually the encoded stream is relatively long — 1024 bits would be a short message.

I got into an argument with a colleague about RAID levels (specifically RAID5) and whether the redundancy was accomplished through parity or ECC. The standard sources all refer to the RAID5 array ...
