Abstract
The present disclosure relates to a method for interleaving a stream of input data blocks, the method comprising steps of: subdividing a block into sub-blocks of fixed size in number of data rows and data columns, the sub-blocks being distributed in the block in rows of sub-blocks and in columns of sub-blocks, transferring the data contained in the block into a first memory, while respecting the order of the data in the input stream, transferring the data contained in the block by row of sub-blocks, into a second memory in which the data of each sub-block is accessible from the address of the sub-block, transferring the data of each sub-block by column of sub-blocks, from the second memory into a third memory, by putting back the data of each sub-block in data rows and columns, and transferring the data by data column from the third memory into an output stream.
