An error detection method used for digital communication which intends to reduce the probability of outputting the speech obtained by decoding the data that includes an error. The speech data encoded in an error detection code and an error correction code is transmitted. On a receiving side, the...
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 us...
To implement a CRC algorithm all we have to do is implement CRC division. There are two reasons why we cannot simply use the divide instruction of whatever machine we are on. The first is that we have to do the divide in CRC arithmetic. The second is that the dividend might be ten me...
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
Reducing the number of check bits used in an error code is often important to reduce the overhead of error detection and correction. Parity, SEC, SECDED, DECTED, and CRC codes are common error detection and correction codes used to protect memory structures. Parity codes provide perhaps the ...
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...
We have enabled the CRC_ERROR pin and we want to instantiate the block cyclone10lp_crcblock in order to retrieve the CRC calculated during configuration. The cyclone10lp_crcblock is instantiated in a dedicated IP (attached with this message) where the CRC is output after ...
The original Hamming code uses 7 bits to store 4 bits of information with redundancy bits used for correction, and detection of errors. In STM32 devices, selected RAM and flash memories are protected using a SEC-DED algorithm based on Hamming principle...

crc-statistics: The number of CRC error packets exceeds the alarm threshold. dual-active: The stack is split and a dual-active fault occurs, and the service interfaces (except the reserved interfaces) on the switch that fails the competition enter the Error-Down state. ...
