ENERGY-INTERFERENCE-FREE DEBUGGER FOR INTERMITTENT ENERGY-HARVESTING SYSTEMS

摘要

An energy-interference-free debugger is disclosed for debugging software resident on energy-harvesting target devices, which may periodically lose power and therefore exhibit intermittent execution of the software. The debugger is implemented as a combination of hardware and software and provides, in addition to the traditional debugging tools, the ability to monitor and modify the energy level on the target device, the ability to set breakpoints based on the energy level on the target device, and the ability to isolate portions of the code executing on the target device from energy-related failure during debugging. The debugger is able to remain isolated from intermittent power in passive mode and to create an illusion of an untouched energy reservoir in active mode.
