摘要： A processing system and method are provided for reconstituting a block of pixels from bins generated by a Mojette Transform, using a processing and calculation unit (UTC), a bin memory (MB), and a pixel memory (MP). The unit is configured to carry out the operations of reconstructing the pixels, which are performed by reading the bins in the bin memory, reading the reconstructed pixels in the pixel memory, and writing the reconstructed pixels in the pixel memory, such that the steps of reconstructing the pixels do not include an operation of writing bins in the bin memory.

摘要： Systems, apparatuses, and methods for generating error correction codes (ECCs) with two check symbols are disclosed. In one embodiment, a system receives a data word of length N−2 symbols, wherein N is a positive integer greater than 2, wherein each symbol has m bits, and wherein m is positive integer. The system generates a code word of length N symbols from the data word in accordance with a linear code defined by a parity check matrix. The parity check matrix is generated based on powers of γ, wherein γ is equal to β raised to the (2m/4−1) power, β is equal to a raised to the (2m/2+1) power, and α is a primitive element of GF(2m). In another embodiment, the system receives a (N, N−2) code word and decodes the code word by generating a syndrome S from the code word using the parity check matrix.

摘要： A frame coding unit generates individual picture signal information from a moving picture signal, and outputs a frame code value which is a numeric value to be obtained as a result of coding picture signal information of each frame. A variable length coding unit decomposes the frame code value into unit frame code values which are basic units of coding, converts the unit frame code values into frame code words using only a single code table, and constructs a frame stream by combining the converted frame code words. A multiplexing unit multiplexes a header stream which is constructed through a method equivalent to a conventional method and the frame stream, and constructs a picture coded signal.

摘要： A memory read-channel is provided with selective transmission of error correction data. The disclosed read-channel improves throughput and reduces power consumption when error correction codes are unnecessary. The data read from a memory device comprises user data, error detection data and error correction data. In one embodiment, the error detection data is evaluated to determine if there is a data error; and the error correction data is transmitted only if a data error is detected. In another variation, the error detection data is evaluated during data transmission to determine if there is a data error and the transmission is suspended if a data error is detected. Typically, the error detection data comprises a cyclic redundancy check and the error correction data comprises parity check data.

摘要： A method for encoding data words into a frame is provided. Input data words are received on a first bus having a first width. The input data words are buffered so as to output intermediate data words onto a second bus having a second width. A transcode bit is generated from the intermediate data words, and a set of parity bits is generated from the intermediate words using a syndrome generator, where the syndrome generator uses a number of bits that are equal to the second width. A frame is then generated from the intermediate data words and the set of parity bits and is output to a third bus having the first width.

摘要： In a cyclic code decoding method, a decoder analyzes a received codeword to identify unreliable symbols in the codeword, and sets candidate syndrome patterns accordingly. Then, a syndrome calculator calculates evaluated syndrome values associated with one of the candidate syndrome patterns, and an error location polynomial (ELP) generator generates an ELP according to the syndrome values. An error correction device corrects the errors in the codeword according to theELP when a degree of the ELP is not more than a threshold value, and the syndrome calculator adjusts the syndrome values and the ELP generator generates another ELP according to the adjusted syndrome values when otherwise.

摘要： A method begins by a dispersed storage (DS) processing module receiving one or more pairs of coded values. The method continues with the DS processing module creating a received coded matrix from the one or more pairs of coded values. When the received coded matrix includes a decode threshold number of pairs of coded values, the method continues with the DS processing module generating a data matrix from the received coded matrix and an encoding matrix, reproducing a one of a first plurality of data segments from a first plurality of data blocks of the data matrix, and reproducing a one of a second plurality of data segments from a second plurality of data blocks of the data matrix, wherein the one of the first plurality of data segments and the one of the second plurality of data segments maintain the time alignment of a first and second data streams.
