    Abstract: The invention relates to de-interleaving successive sequences of interleaved data samples extracted from a virtual memory having L0 columns and C0 rows, in particular for high-throughput applications. The method comprises the steps of:

    receiving each sequence of said interleaved data samples and writing row by row said received sequences of interleaved data samples in a de-interleaving memory array (2) having L rows and C columns, L being superior or equal to L0 and C being superior or equal to C0, and
    de-interleaving the data samples stored in said de-interleaving memory array (2) sub-array by sub-array, the used predetermined sub-array being a square cluster array having a predetermined number SQ of rows and columns, the number L of rows and the number C of columns of the de-interleaving memory array (2) being multiples of the number SQ of rows and columns. De-interleaving the de-interleaving memory array (2) sub-array by sub-array allows to avoid memory re-use bottleneck and allows to decrease memory access rate.

    Abstract: A method and device for handling write access conflicts in interleaving, in particular for high-throughput turbo decoding for wireless communication systems; the device comprises N interleaving buffers (CLk) that are respectively connected to N producers (PRk), an LLR distributor means and N single port target memories (TMk). At any time step, each interleaving buffer receives m LLR inputs from the producers and has to write up to M of these into a register bank (RBk), which comprises W registers. M denotes the maximum number of concurrent write operations supported per time step and W denotes the maximum buffer size. M and W are design parameters and are chosen for the standard case and not for the worst case. m-M producers have to be stalled whenever m is larger than M and m producers have to be stalled whenever a buffer overflow occurs (more than W LLR values). Finally, at any time step one LLR value is fetched from the register bank and written to the SRAM interleaving memory.

    Abstract: Method of de-interleaving S2 received sequences of interleaved received data samples respectively issued from S2 physical channels (phc_0,phc_1,...,phc_S2-1) and able to be associated with S1 output transport channels (otc_0,otc_1,...,otc_S1-1). Said S2 received sequences have been delivered, before transmission, by a two-stages multi-interleaving device (2), from S1 initial sequences of ordered data samples respectively associated to S1 initial transport channels (itc_0,itc_1,...itc_S1-1). Said two-stages multi-interleaving device (2) comprises a first stage (3) including S1 interleaving blocks (Int1_0,Int1_1,...Int1_S1-1) respectively associated to the S1 initial transport channels (itc_0,itc_1,...itc_S1-1), a second stage (4) including S2 interleaving blocks (Int2_0,Int2_1,...Int2_S2-1) respectively associated to the S2 physical channels (phc_0,phc_1,...,phc_S2-1) and an inter-stage of predetermined data-routing functions (5) connected between said first and second stages (3,4). The two stages of interleavers (3,4) and the inter-stage of predetermined data routing functions (5) are merged into one stage and second and first stage de-interleaving is performed when the received data samples are written to memory elements (me_0,me_1,...me_S1-1) that are associated with the S1 output transport channels.
