Abstract
A data interleaving system (20) provides flexibility by performing the interleaving function in a high level controller (32) and a separate low level controller (34). The high level controller (32) receives commands to operate on a codeword basis, in which a codeword is made up of a plurality of symbols which are grouped into a programmable number of frames. The low level controller (34) operates under the direction of the high level controller (32) on a symbol-by-symbol basis. By separating the codeword level tasks from the symbol level tasks, the data interleaving system (20) is able to accommodate various ratios of the number of frames per codeword without significant complexity. An analogous data de-interleaving system (220) includes a high level controller (232) and a low level controller (234).
