A system includes a cut-through buffer operable to be asynchronously read while being written at different clock frequencies. The system also includes a controller operatively connected to the cut-through buffer. The controller is operable to write one or more values into the cut-through buffer in a first clock domain and compare a number of values written into the cut-through buffer to a notification threshold. A notification indicator is passed from the first clock domain to a second clock domain based on determining that the number of values written into the cut-through buffer meets the notification threshold. Based on receiving the notification indicator, the cut-through buffer is read from the second clock domain continuously without pausing until the one or more values are retrieved and any additional values written to the cut-through buffer during the reading of the one or more values are retrieved.
