In-situ power monitoring scheme and its application in dynamic voltage and threshold scaling for digital CMOS integrated circuits

Real-Time Power Sensors for Intelligent Power Management and Beyond

“…Therefore, it can be treated as a resistor with anon-resistance of R sleep . A concurrent study reported in [8] also attempts to utilize this voltage drop to proportionally integrate a capacitor and provide a quantized two-bit output. However, this two-bit output of the monitor may increase the number of iterations the power management loop has to go through before converging to the optimal operating point.…”

Thermal system identification (TSI): A methodology for post-silicon characterization and prediction of the transient thermal field in multicore chips

“…Hence, by controlling the period of the sleep control signal we can modulate the spectral behavior of the generated power patterns. The on-chip power monitors can be used to sense the core level power [27]. Application Driven Power Spectra: The second approach is to run multiple test applications in individual cores and measure power and temperature to compute the filter response.…”
