<p>A block interleaver is provided using a relatively small register file and a larger random access memory (RAM). In one embodiment, the size of the RAM is larger than the size of the register file by at least one order of magnitude. As a result, the register file consumes significantly less power than the RAM for similar operations. The register file receives a stream of sequential data values and stores the data values in a column order. The data values are then read from the register file in a row order. The data values read from the register file in a row order are then written to the RAM in a row order. The data values are then read from the RAM in a row order, thereby creating an interleaved data stream.</p> |
