摘要： A decoder and decoding method are described, in which a syndrome is calculated from a codeword in a syndrome generator, an error polynomial is generated based upon the syndrome in an error polynomial generator, an error location is determined from the error polynomial in the error location generator, an error magnitude is calculated from the error polynomial in the error magnitude generator and the codeword is corrected by a error corrected codeword generator responsive to location and error magnitude. An intra-decoder block messaging scheme is described in which one or more components generate inactivity messages to signal an ability to process data corresponding to a next codeword. A dual Chien search block implementation is described in which Chien block is used to determine the number of errors corresponding to a specified codeword, separately from error location and magnitude calculations performed by the Chien/Forney block. An enhanced Chien search cell architecture is described which utilizes an additional Galois field adder to synchronize the codeword and error vector, thereby decreasing delay and expense corresponding to an error correcting block implemented with a LIFO register.

摘要翻译：描述了一种解码器和解码方法，其中从校正子发生器中的码字计算出校正子，根据误差多项式生成器中的校正子产生误差多项式，根据误差位置中的误差多项式确定误差位置发生器，误差幅度由误差多项式在误差幅度发生器中计算，并且码字由响应于位置和误差幅度的纠错码字发生器校正。描述了解码器内消息传送方案，其中一个或多个组件产生不活动消息以发出处理对应于下一个码字的数据的能力。描述了双Chien搜索块实现，其中Chien块用于确定与指定码字相对应的错误的数量，与由Chien / Forney块执行的错误位置和幅度计算分开。描述了一种增强的Chien搜索单元架构，其利用附加的伽罗瓦域加法器来同步码字和误差向量，从而减少与利用LIFO寄存器实现的纠错块相对应的延迟和费用。

摘要： A system for processing data packets comprising a plurality of data processing blocks and a controller, which allows the configuration parameters used in processing the data blocks to be updated in each data processing blocks at the data packet boundary. The present invention involves a system that utilizes a handshaking method for synchronously exchanging data between data processing blocks, wherein the data processing blocks update configuration parameters based on the type of networking standard used. Each data processing block identifies a first data block in the data packet and transmits a first data signal along with a first output data block of the data packet, wherein the block updates the configuration parameters from the controller only when the first data signal is present. In this manner, the first data signal, which is indicative of the data packet boundary, is propagated along the sequence of data processing blocks.
