![]() ![]() LFSR find its wider application in Built-in-Self-Test, signature analyzer etc., whereas here it is used to form parity bits to concatenate with message bits for the formation of a codeword. One of the main components of BCH encoder is LFSR (Linear Feedback Shift Register). This codeword is sent to the receiver to detect any error during the transmission. The generated check bits of the BCH encoder are appended with the message bits to form a codeword. BCH codes are widely been used for error detection and correction. Some DSP algorithms are used to overcome the delays by increasing the speed. ![]() So, two types of LFSR is been designed to reduce the iteration bound and the critical path. As far as the memory is concerned the testing should not consume more time. But the NAND FLASH memories are competing in the market due to its low power, high density, cost effectiveness and design scalability. Author : E.K.Sharmitha, T.Sathya and B.S.Saromena Aarthi Pages : 2229-2235Įrror correction is one of the important technique for detecting and correcting errors in communication channels, memories etc., Errors are associated with all types of memories. ![]()
