  • Interleaver with parallel address queue arbitration dependent on which queues are empty
    Patent number: 8775750
    Abstract: An interleaving method includes: generating multiple read-addresses for respective bits of multiple write-words; queuing the read-addresses in parallel in multiple address queues; selecting an address queue among the address queues that is not empty based on status of each address queue; decoding the address from the selected address queue to a read-address and a bit-address; extracting a read-word from data to be interleaved based on the read-address; selecting a write-bit from the read-word based on the bit-address; arbitrating an individual write-bit to one of the write-words based on an address queue ID of the selected address queue; and generating write-addresses for respective write-words.
