Xilinx Blocks

When the branch lengths are specified as an array, the block operates the same in either interleaver or deinterleaver mode because the array fully defines the length of all the branches. The array must have length B, matching the number of branches.

The reset pin (rst) will set the commutator arms to branch 0, but will not clear the branches of data.

Block Interface

The Interleaver/Deinterleaver block has two input and one output ports. The input port, din, must be between 1 and 256 (inclusive) bits. The reset port, rst, must be of type UFix1_0. The size of the output port, dout, is the same as the input port, din.

Parameters specific to the block are:

Mode: Interleaver or Deinterleaver

Number of Branches: 1 to 256 (inclusive)

Length of Branches: 1 to MAX (inclusive). MAX depends on the number of branches and size of core input. Branch length must be an array of either length one or number of branches. If the array size is one, the value is used as a constant difference between consecutive branches. Otherwise, each branch has a unique length.

Memory Type: Automatically chosen, block RAM or distributed RAM

Other parameters used by this block are described in the Common Parameters section of the previous chapter.

Xilinx LogiCORE

The block always uses the Xilinx LogiCORE: Interleaver/Deinterleaver v1.1.
