Abstract: For determining a power consumption of electrical circuitry, at least one device executes at least a portion of a software application having an effect on a current through the electrical circuitry. A current is generated through a transistor for mirroring the current through the electrical circuitry. In response to a control word, a reference current is generated. In response to executing the portion of the software application, the control word is varied to determine a value thereof that causes the reference current to approximately equal the current through the transistor, in a manner that correlates the effect of the portion of the software application on the current through the electrical circuitry.

Abstract: This disclosure describes techniques for transferring data from an analog-to-digital converter (ADC) to a host device. The techniques may determine whether an ADC is operating in a quiet conversion time period, and selectively deactivate a digital data output of the ADC when the ADC is operating in the quiet conversion time period. This may allow an ADC to transfer data during both the conversion and acquisition phases of the ADC (rather than just during the acquisition phase), thereby increasing the data throughput of the ADC for a given transfer clock speed. The techniques may further allow data to be transferred during the conversion phase of an ADC without requiring a host device to be aware of the quiet conversion time period requirements of the ADC. In this way, the data throughput of an ADC data transfer may be increased with relatively little additional complexity added to a host device.

Abstract translation: 本公开描述了用于将数据从模数转换器（ADC）传送到主机设备的技术。 这些技术可以确定ADC是否在安静的转换时间段内运行，并且当ADC在安静的转换时间段内运行时，可以选择性地禁用ADC的数字数据输出。 这可能允许ADC在ADC的转换和采集阶段（而不是在采集阶段期间）传输数据，从而增加ADC在给定传输时钟速度下的数据吞吐量。 这些技术还可以允许在ADC的转换阶段期间传送数据，而不需要主机设备了解ADC的安静转换时间段要求。 以这种方式，可以增加ADC数据传输的数据吞吐量，同时相对较少的附加复杂性被添加到主机设备。
