ABSTRACT:
Clocking Chien searching at different frequency than other Reed-Solomon (RS) ECC decoding functions. An efficient implementation allows for a fast clock signal to govern the operation of the more computationally and time-intensive portions of the error correction code (ECC) time budget. For example, at least one module and/or decoding function within the ECC decoding is governed by using a first clock signal, and at least one other module and/or decoding function (or all the other modules and/or decoding functions) is/are governed by using a second clock signal. In one implementation of Reed-Solomon (RS) decoding, the Chien searching function is operated using a faster clock signal than at least one other RS error correction decoding function thereby allowing for a significant reduction in area and power than other architectural trade-offs.
