  • Serial wire debug bridge
    Patent number: 9632137
    Abstract: An integrated circuit (IC) having a bridge for interfacing a debugger and method of operating the same is provided. In one embodiment, an IC includes a debug control circuit and a debug interface block (DIB) implemented thereon. The DIB is coupled to the debug control circuit. The IC also includes an interface for a debugger and a number of interfaces for external circuits, each of the interfaces being coupled to the debug control circuit. The debug control circuit may function as a bridge for coupling an external debugger to the DIB and to external circuits coupled to the IC through corresponding ones of the interfaces. The debug control circuit may establish a connection between the debugger and one of the external circuits. Communications between the debugger and the external circuit may be conducted while bypassing the DIB.
