Abstract
This article presents an extensive study which was performed on Infineon’s Aurix2G microcontroller to evaluate the impact of overclocking and underclocking on several parameters such as throughput, current, and power. Guided by the study, both overclocking and underclocking were utilized together to develop a dynamic frequency control approach to application development. An experimental application was divided into an underclocked zone and an overclocked zone. Switching between these two zones provided benefits in multiple application scenarios as compared to various static frequency approaches. In the evaluated application scenarios, the dynamic frequency control approach provided up to 33% reduction in execution time and up to 49% reduction in overall energy consumption, in comparison with the default static approach. The proposed approach also provided a reduction in average current and power in most of the evaluated application scenarios.
