摘要： An emulation unit/target processor interface apparatus senses the target processor I/O voltages using filters to reduce the noise level and provides the rest of the interface apparatus with a target reference voltage level. The reference voltage is used to create threshold voltages, termination voltages and drive levels appropriate to provide an interface with the target processor. Power loss in the target processor is also detected so that drive signals can be removed from the target processor to avoid damaging the target processor and to prevent the target processor from being energized by the emulation unit.

摘要： Systems and methods for improved power profiling of embedded applications are presented. These inventions provide the ability to unobtrusively measure the power consumption of an embedded application as the application is executing on its target hardware. The unobtrusiveness is achieved by using programmable emulation circuitry in the target system processor and available device debug terminals on the test port.
