In one embodiment, interleaved signals in a receiver are accessed by memory pointers and delivered to data stream locations without the need to transfer data to an intermediate physical buffer.

De-interleaver method and system

Embodiments of the present invention provide a fast, software-implemented data scrambling system for data communications. For pseudo-random codes that are periodic within a predetermined number of bits, a memory array may be populated with segments of the code, one entry in the array starting at a unique bit position within the code. During data scrambling, a seed code may be used to identify a first entry from the array that should be used for scrambling. Thereafter, subsequent segments may be retrieved by traversing the array in a regular fashion. By calculating the code before use and by populating the array prior to processing of any source data, the system is very fast.

Fast-software-implemented pseudo-random code generator

In one embodiment, an optimized interleaving instruction is provided. The interleaving instruction facilitates a bit-level interleaving of two streams of data stored in two source registers into a combined stream of data.

Method and apparatus for interleaving data streams

A method and system for interleaving blocks of data. The method includes partitioning an input bitstream into multiple bitstreams, interleaving the multiple bitstreams into a single bitstream, partitioning the single bitstream into multiple different bitstreams, and shuffling the bits of the different bitstreams. Exemplary applications include the IEEE 802.11standard interleaver stage.
