摘要
An embedded universal serial bus (USB) debug (EUD) for multi-interface debugging in an electronic system is disclosed. Electronic systems contain complex integrated circuits (ICs) that require extensive testing and debugging to ensure superior quality and performance. In an exemplary embodiment, the EUD is provided in the electronic system. The EUD is configured to send control information to and / or collect debugging information from a plurality of internal debugging interfaces in the electronic system. The EUD is also configured to convert the debugging information into a USB format so that the debugging information can be accessed externally through a USB interface provided by the electronic system. The EUD can provide non-intrusive monitoring of electronic systems. While the EUD is enabled, the electronic system can use the USB port to communicate in mission mode. In addition, while the EUD continues to function, the electronic system can turn all system clocks on or off during the power save mode.
