Abstract :
The power management system described in this paper enables more than 3× increase in power-constrained performance over the previous generation of SPARC server CPUs [2]. The low latency and high performance of the system is possible due to accurate, high-bandwidth sensors, fast on-die control and finegrained actuation implemented using both clock cycle skipping and DVFS, as required by the time constants of system constraints.
