    摘要: In one embodiment, a system comprises JTAG functionality that implements at least a portion of a JTAG protocol. The JTAG functionality supports a test data in (TDI) line, a test data out (TDO) line, a test rest (TR) line, a test mode state (TMS) line, and a test clock (TCLK) line. The system further comprises a debug interface to communicatively couple the system to a debug device external to the system. The debug interface comprises a transmit (TX) line, receive (RX) line, and a clock (CLK) line. The system transmits data output by the JTAG functionality on the TDI input on the RX line of the debug interface and receives data from the debug device on the TX line of the debug interface and provides the received data to the JTAG functionality on the TDO line, TR line and the TMS line.

    摘要: In one embodiment, a system comprises debug functionality, a debug interface communicatively coupled to the debug functionality, and a hardware key interface. Communication with the debug functionality over the debug interface is not permitted if an authorized hardware key is not communicatively coupled to the hardware key interface.

    摘要: A package includes a chassis, a plurality of components arranged within the chassis, a plurality of RFID devices, and at least one processing device. The RFID devices are arranged at a plurality of locations to form an array configured to authenticate compliance of the actual configuration of the package with a model configuration. The processing device is configured to communicate with the RFID devices, determine if the actual configuration of the package is in compliance with the model configuration based on communications with the RFID devices, and set an operational mode of one or more of the components of the package in response to determining if the actual configuration of the package is in compliance with the model configuration.
