The speech data encoded in an error detection code and an error correction code is transmitted. On a receiving side, the data with an error detected in either one of decoding of the error correction code and CRC checking is interpolated so that it is possible to prevent the data which ...
Functions: crcConfig, crcGenerate, and crcDetect Create a configuration object by using the crcConfig function. To generate CRC code bits and append them to input data, call the crcGenerate function specifying an input message and the CRC configuration object. To detect errors in input data usin...
the initial value has no affect on the strength of the CRC algorithm, the initial value merely providing a fixed starting point from which the register value can progress. However, in practice, some messages are more
Parity, SEC, SECDED, DECTED, and CRC codes are common error detection and correction codes used to protect memory structures. Parity codes provide perhaps the simplest form of fault detection. An even parity code needs one check bit that is the XOR of all the data bits. Parity codes can ...

CRC算法类操作总结: Choose a width W, and a poly G (of width W). 1.选择宽度W和除数G(宽度W)。 Append W zero bits to the message. Call this M'. 2.在消息后附加W个零位。叫这个M。 Divide M' by G using CRC arithmetic. The remainder is the checksum. ...

A memory system provides data error detection and correction and address error detection. A cyclical-redundancy-check (CRC) code generates address check bits. A 32-bit address is compressed to 6 address check bits using the CRC code. The 6 address check bits are concatenated with 64 data bits...
For SEU mitigation in Stratix iv GX device, I enabled ''Enable error detection CRC" from Device and Pin Options in Quartus II 13.1. But while synthesis got the error message that " Error(21216): Cannot enable error detection cyclic redundancy check without instantiating the ALTERA_CRCERROR_VE...
