In this experiment, an internal AM574x board is used to gather thermal data with different processor loading and ambient temperature. Ambient temperature is controlled with a programmable environmental chamber.
The collected data can be utilized to correlate the thermal performance of the processor and power consumption at a given processor load and junction temperature, based on ambient temperature and thermal management.
Tests were repeated with the following thermal management:
