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.
