Abstract: A dynamic power meter circuit receives a set of clock signals. The clock signals are summed by a clock sum adder, thereby generating a clock sum value. A dynamic power meter output value is generated based at least in part on the clock sum value. In one particular example, a dynamic power meter circuit receives clock signals and from them generates a clock sum model sub-value. The dynamic power meter circuit also receives event signals, and from them generates an architectural event model sub-value. A corresponding pair of clock sum model sub-value and architectural event model sub-value are then ratiometrically combined, thereby generating a dynamic power meter output value. Due to the use of both event signals and clock signals, a stream of dynamic power meter output values is generated that more closely tracks actual dynamic power of a circuit being monitored.

Abstract translation: 动态功率计电路接收一组时钟信号。 时钟信号由时钟和加法器相加，从而产生时钟和值。 至少部分地基于时钟和值产生动态功率计输出值。 在一个具体示例中，动态功率计电路接收时钟信号，并从中产生时钟和模型子值。 动态功率计电路还接收事件信号，并从它们生成建筑事件模型子值。 然后将对应的一对时钟和模型子值和架构事件模型子值进行比例组合，从而生成动态功率计输出值。 由于使用了事件信号和时钟信号两者，所以产生动态功率计输出值流，其更紧密地跟踪被监控电路的实际动态功率。
