    • A system (2) can include a processing core (6) to execute machine readable instructions. The system (2) can also include a memory (8) accessible by the processor core (6). The memory (8) can include preprogrammed test data (10) that characterizes one of an impedance of a processor (3) and a current output to the processor (4) during execution of a test routine. The processor (4) can include the processing core (6) and the one of the impedance of the processor (4) and the current output to the processor (4) is based on a power measurement taken during execution of a test routine. The power measurement can be taken with a current sensor that is at least one of lossy or at least about 98% accurate.
    • 系统(2)可以包括执行机器可读指令的处理核心(6)。 系统(2)还可以包括可由处理器内核(6)访问的存储器(8)。 存储器(8)可以包括在执行测试例程期间表征处理器(3)的阻抗和到处理器(4)的电流输出中的一个的预编程测试数据(10)。 处理器(4)可以包括处理核心(6),并且处理器(4)的阻抗和输出到处理器(4)的电流中的一个是基于在执行测试例程期间获取的功率测量。 功率测量可以使用电流传感器进行测量,该电流传感器至少有一个损耗或至少约98%的准确度。
