ABSTRACT:
An error correction encoding apparatus for processing input data with an encoding for error correction, including first delay circuitry for applying differing delay to data words to convert input data in a first array state into data words in a second array state, a first error correction encoder for generating first check words from data words in the second array state, second delay circuitry for applying differing delay to the data words in the second array state and the first check words to generate data words and check words in a third array state, and a second error correction encoder for generating second check words from the data words and the check words in the third array state, with the delays applied by the first and second delay circuitry set so that the array states of the data words in the first and the third array states are the same. In other embodiments, the invention is an error correction decoding apparatus including a first error correction decoder for processing input data words and check words in a third array state by error correction by a second error correction code using a second check word series, first delay circuitry for applying differing delay to the corrected data words and check words from the first error correction decoder to generate data words in a second array state and first check words, a second error correcting decoder for error-correcting the data words in the second array state by a first error correction code using the first check words, and second delay circuitry for applying differing delay to the corrected data words from the second error correcting decoder to generate data words in a first array state.
