Octa-Core CPU Performance/Power Tuning on the Allwinner A80T
This video shows one of the automated performance testing tools used during A80’s big.LITTLE tuning process. big.LITTLE is an innovative technology used to balance Cortex-A7’s low power with Cortex-A15’s high performance. An important part of the tuning process is frequent regression testing – that is, checking how performance and power consumption are affected by firmware updates. In this video, a simple automated benchmark test is running after a firmware update.
Quick-and-dirty tests like these allow software engineers to more efficiently check system performance and power consumption after low-level parameter changes.
