Detailed Description

The XOROperator performs Exclusive OR on bits in a value.

XOR has the following truth table:

When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.

Example

To perform exclusive OR with a signal value, add an XOROperator<unsigned short> into a Signal<unsigned short> in Configure mode. Then go into the XOROperator that was added, add an Argument<unsigned short> and set Value to 5.

How to Run the Example

To run the example from CDP Studio, open Welcome mode and find it under Examples. Next, in Configure mode right-click on the system project and select Run & Connect. See the Running the Example Project tutorial for more information.

Set the signal Value containing the XOR operator to 0x0008 (8), and verify that the value after the operator has been applied becomes 0x000D (13)

Actual Processing Code of the XOROperator

unsigned int XOROperator<T>::Process()
{
  T outputValue = static_cast<T>(m_input);
  for (auto arg : this->m_arguments)
    outputValue ^= static_cast<T>(*arg);
  m_output = outputValue;

  return STATUS_OK;
}
