ABSTRACT:
In one embodiment, a debugger for a hardware-implemented operating system that supports one or more processors includes a host debug and a user interface. The host debug is operable to connect to a kernel processing unit of the hardware-implemented operating system via a test interface such as a Joint Test Access Group (JTAG) interface, to request information concerning internal objects of the kernel processing unit during the operation of the processors, and to receive the requested information without disturbing the operation of the processors. The user interface is then used to present the requested information to the user. In one embodiment, the debugger further includes a target resident debug server that is scheduled by the kernel processing unit to execute debugging commands issued by the host debug (e.g., a command to collect information resident in the processor's data space, a command to set a breakpoint, a command to respond to a breakpoint, etc.). The target resident debug server executes the debugging commands without unreasonable interference with the operation of the processors.
