Abstract
Methods and structure described herein provide for reducing the overall delay of an RS encoder/decoder without changing the essential functionality of the RS encoder/decoder. In one embodiment, a cascade module reduces the combinatorial logical delay by reducing the total number of logical devices. In doing so, the cascade module couples encoder/decoder slices into blocks. A first block of the encoder/decoder slices is selectively operable in parallel with a second block of encoder/decoder slices. The number of encoder/decoder blocks is less than the overall number of encoder/decoder slices. The cascade module may also include a switch that selects encoder/decoder slices as needed, thereby providing for the implementation of the RS encoder/decoder with fewer logical devices.
