摘要： A control module includes an encoder module, which generates a first code word for multiple drives. A detector module, in response to detecting an error in a first drive subsequent to generation of the first code word, initiates replacement of the first drive with a second drive. The encoder module generates a second code word for the second drive. A mapping module maps physical locations of data in the drives to logical locations of the first code word, assigns a predetermined value to one of the logical locations corresponding to the first drive to identify an unused logical location, and assigns the unused logical location to the second drive based on the predetermined value. A difference module generates a third code word based on the first and second code words. The encoder module generates an updated code word for the multiple drives based on the first and third code words.

摘要： Power-saving and area-efficient BCH coding systems are provided that employ hybrid decoder architectures. The BCH decoder architectures comprise both special-purpose hardware and firmware, thereby taking advantage of both the speed of special-purpose hardware and the energy-efficiency of firmware. In particular, the error correction capabilities of the BCH decoders provided herein are split between a hardware component designed to correct a single error and a firmware component designed to correct the remaining errors. In this manner, firmware operation is bypassed in situations where only one error is present and the complexity of the necessary hardware is significantly reduced.

摘要： The disclosed technology provides systems and methods for encoding data based on a run-length-limited code and an error correction code to provide codewords. The codewords include RLL-encoded data that are produced based on the RLL code, and parity information that are produced based on the error correction code. The parity information is interleaved among the RLL-encoded data. In one embodiment, the codeword is produced by separately producing the RLL-encoded data and the parity information, and interleaving the parity information among the RLL-encoded data. In one embodiment, the codeword is produced by producing the RLL-encoded data, and using erasure decoding to compute the parity information.

摘要： A Reed-Solomon (RS) coding system is provided that can employ an RS code of varying correction power, and which can maintain a small area requirement. The Reed-Solomon coding system can include an RS encoder and an RS decoder. Both of these components can be implemented using primarily constant multipliers rather than more area-consuming general multipliers. For example, the programmable encoder can be realized by implementing polynomials with constant coefficients rather than variable coefficients, and a Berlekamp-Massey algorithm performed by the decoder can be realized using a serial implementation. To further reduce the area of the coding system, hardware sharing can be utilized between the RS encoder and the RS decoder.
摘要翻译：提供了一种可以采用不同校正功率的RS码的Reed-Solomon（RS）编码系统，可以保持小面积要求。里德 - 所罗门编码系统可以包括RS编码器和RS解码器。这些组件都可以使用主要的恒定乘法器来实现，而不是使用更多的占用空间的一般乘法器。例如，可编程编码器可以通过实现具有常数系数而不是可变系数的多项式来实现，并且可以使用串行实现来实现由解码器执行的Berlekamp-Massey算法。为了进一步减小编码系统的面积，可以在RS编码器和RS解码器之间利用硬件共享。
