<p>A number of different devices, systems and methods are used in connection with routing of signals between components. According to one embodiment of the present invention, a device is implemented for communicating debug trace data between components that each communicates the data using an advanced microcontroller bus architecture (AMBA) 3 advanced-trace-bus (ATB) interface that is consistent with the CoreSight Architecture Specification Rev 1.0. The components communicate using signals operating at different frequencies and/or voltages, respectively. The device has a buffer (212) for storing data received from the first component (102), the data received from the first component (102) being transmitted according to a first clock (112). An output circuit (213) transmits data stored in the buffer (212) using a second clock (116) having a frequency that is different from a frequency of the first clock (112).</p> |
