Hotspot-Limited Microprocessors Direct Temperature and Power Distribution Measurements.

An experimental technique is presented, which allows for spatially-resolved imaging of microprocessor power (SIMP). In a first step this method utilizes infrared (IR) thermal imaging, while the processor is effectively cooled using an IR-transparent heat sink. In the second step the underlying power...
