De-interleaving on an as-needed basis

摘要

One embodiment is an apparatus having a memory, a controller, and a de-interleaving module. The memory is configured to store portions of a set of interleaved values, where the set of interleaved values correspond to a single application of an interleaving mapping to a set of un-interleaved values. The controller is configured to retrieve each portion from an other memory that stores the set of interleaved values by moving the portion from the other memory to the memory. The de-interleaving module is configured to de-interleave the interleaved values in at least one of the portions to generate a de-interleaved portion such that processing downstream of the de-interleaving module can begin processing the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module.

1. An apparatus comprising:
memory configured to store portions of a set of interleaved values, wherein the set of interleaved values correspond to a single application of an interleaving mapping to a set of un-interleaved values; a controller configured to retrieve each portion from an other memory that stores the set of interleaved values by moving the portion from the other memory to the memory; and a de-interleaving module configured to de-interleave the interleaved values in at least one of the portions to generate a de-interleaved portion such that a processing module downstream of the de-interleaving module can begin processing the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module, wherein the processing module downstream of the de-interleaving module comprises at least one of:
a removal module configured to begin removing at least one of an acknowledgement message, and a negative acknowledgement message from the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module,a de-rate matching module configured to begin de-rate matching on the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module; anda hybrid automatic-repeat request module configured to begin hybrid automatic-repeat request combining on the de-interleaved portion before all of the interleaved values in the set of interleaved values are de-interleaved by the de-interleaving module.
