The Xilinx Threshold block tests the sign of the input number. If the input number is negative, the output of the block is -1; otherwise, the output is 1. The output is a signed fixed-point integer that is 2 bits long. The block has one input and one output.
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 topic Common Options in Block Parameter Dialog Boxes.
The block parameters do not control the output data type because the output is always a signed fixed-point integer that is 2 bits long.
The Threshold block does not use a Xilinx LogiCORE™ ™.
