Abstract
A resource optimized interleaving/deinterleaving system comprising a Reed-Solomon encoder, a Reed-Solomon decoder, a state machine, and a memory is disclosed. Reed-Solomon encoded fastpath data is stored in memory. A stream of interleaved data with predefined parameters S, the number of DMT symbols per each Reed-Solomon codeword, D, the interleaving depth, and N, the block length is written into system memory at an adaptable rate determined by the Reed-Solomon encoder. The previously stored Reed-Solomon encoded fastpath data is automatically reassembled and buffered with the interleaved data to form appropriate DMT transmission symbols. The DMT transmission symbols are then read out of the system memory at a rate determined by the next processing function, i.e., tone ordering. A method of using one Reed-Solomon encoder/decoder with the integrated interleaving/deinterleaving system to support dual single latency DMT systems is also disclosed.
