These settings indicate that the black box should have clocks named fast_clk and slow_clk. The fast_clk should have the same frequency as the samples presented to input port #1, and the slow_clk should have the same frequency as output port #1.

Concat

The Xilinx Concat block performs a concatenation of two bit vectors represented by unsigned integer numbers, i.e. two unsigned numbers with binary points at position zero.

The Xilinx Reinterpret block provides capabilities that can extend the functionality of the Concat block.

Block Interface

The block has two input ports and one output port. The two input ports are labeled hi and low. The number input to the hi port will occupy the most significant bits of the output and the number that is input to the low port will occupy the least significant bits of the output.

Block Parameters Dialog Box

The block parameters dialog box can be invoked by double-clicking the icon in your Simulink model.

Parameters used by this block are explained in the Common Parameters section of the previous chapter.

The Concat block does not use a Xilinx LogiCORE.
