Quality of service-aware, scalable cache tuning algorithm in consumer-based embedded devices

To meet energy and quality of service (QoS) constraints in consumer/user-based embedded devices (CEDs), configurable caches can be tuned to a best configuration that consumes the least amount of energy while adhering to QoS expectations. However, due to disparate consumer QoS expectations and a myriad of unknown, third-party CED applications, tuning caches in CEDs is very challenging. In this paper, we propose a quality of service-aware, scalable tuning algorithm for configurable caches, which requires no a priori knowledge of applications or design-time efforts.
