Overview
The Lattice Interleaver/de-interleaver IP core supports rectangular block type and convolutional architectures. Rectangular interleaving arranges the input data row-wise in a matrix. The interleaved data is obtained by reading the columns of the matrix. Convolutional interleaving feeds the input data to a number of branches, each of which has a shift register with pre-defined length. The output data is taken from the branch outputs. Lattice’s Convolutional Interleaver/de-interleaver IP Cores are compliant with ATSC and DVB standards, while the Rectangular Interleaver/de-interleaver is compliant with IEEE 802.16a standard.
