Measuring Power Consumption of the OMAP4430 using the PandaBoard
November 17, 2011
Recently, I performed a series of power measurements on Texas Instrument’s OMAP4430 mobile SoC. The aim of this experiment was to confirm that we can perform such energy consumption measurements with sufficient accuracy for software source-code optimization. The software parallelization tools of Vector Fabrics can be used to lower power consumption, and measurements like these are needed to verify our results. Furthermore, it was my goal to evaluate speed/power trade offs in re-mapping a compute kernel from the multi-core ARM Cortex-A9 host processor onto the PowerVR SGX graphics processing unit.
