I-DVFS: Instantaneous Frequency Switch During Dynamic Voltage and Frequency Scaling

This work presents I-DVFS: a novel approach to perform instantaneously the frequency switch during dynamic voltage frequency scaling (DVFS). The I-DVFS, unlike legacy DVFS, does not require halting an IPs execution to perform a DVFS transition, and thus, the performance overhead of DVFS is both reduced and more deterministic. Such attributes enable the more frequent use of DVFS and, thus, improve ...
