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 ...

Low-Density Parity-Check (LDPC) codes represent a class of error-correcting codes that have fundamentally reshaped the field of digital communications. With their inherently sparse parity-check ...

Low-Density Parity-Check (LDPC) decoder designs have undergone significant evolution, driven by the need for high-throughput, low-complexity and energy-efficient ...

Memory that uses a ninth bit for parity checking. The checking operation is performed by circuits on the motherboard, not on the memory chips themselves. When a ...

Parity checking and checksums are actually the simplest forms of a cyclic redundancy check (CRC). In mathematical terms, a CRC is the result of a polynomial modulus operation, modulo 2 on the message.

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 ...

R-Interface’s LDPC decoder platform provides to all Wireless and Wireline hardware designers an off-the shelf, full standard support, easy-to-integrate and proven solution for the Wimax Mobile ...

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 ...

Last month I showed how coding and error correction allows next-generation broadcast technologies such as DVB-T2 and DVB-NGH to achieve performance very close to the ...
