Abstract
A mapping circuit is provided for mapping first data words into frames of second data words, wherein the first and second data words are of different length. In addition, a de-mapping circuit is provided for de-mapping the frames of second data words into the first data words. The mapping and de-mapping is responsive to address signals that may be stored in a memory such that a desired mapping or de-mapping corresponds to a particular programming of the memory. In this fashion, the mapping and de-mapping is in-system reconfigurable.
