The Vector Concat block concatenates two or more inputs of type vector. The output is cast to an unsigned value with the binary point at zero.


Super Sample Rate (SSR): This configurable GUI parameter is primarily used to control processing of multiple data samples on every sample period. This block enables 1-D vector data support for the primary block operation.

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

Block Interface

The block has n input ports, where n is a value between 2 and 1024, inclusively, and one output port. The first and last input ports are labeled hi and low, respectively. Input ports between these two ports are not labeled. The input to the hi port occupies the most significant bits of the output, and the input to the lo port occupies the least significant bits of the output.

Block Parameters

Double-click the icon in your Simulink® model to open the Block Parameter dialog box.

Parameters specific to this block are as follows:

  • Number of Inputs: Specifies number of inputs, between 2 and 1024, inclusively, to concatenate together.

Other parameters used by this block are explained in the topic Common Options in Block Parameter Dialog Boxes.

The Vector Concat block does not use a Xilinx LogiCORE™ ™.
