Summary: We present MINOTAuR, an open-source RISC-V core designed for timing predictability and compositional timing analysis in a multicore context. With a specific pipeline design, we formally prove that speculative execution does not compromise timing predictability while significantly improving performance. We propose architectural extensions for a return address stack and any cache replacement policy, and implement them in the MINOTAuR core. We demonstrate a trade-off between efficiency and die area consumption, showing that using these extensions achieves performance equivalent to the baseline RISC-V Ariane core while enforcing timing predictability.

Summary: This article introduces a new method called dynamic core scaling (DCS) for managing performance-energy trade-offs in modern processors, which is different from traditional dynamic voltage and frequency scaling (DVFS). DCS dynamically adjusts active datapath resources to achieve optimal performance while minimizing energy consumption, and when combined with DVFS, it can achieve greater energy savings.

Summary: We introduce offloading policies for fog-cloud architectures that consider different performance parameters. We design and develop a three-tier platform, using virtualization techniques, which can be used to deploy different scenarios, with nodes having distinct features, mimicking fog and cloud characteristics. By exploiting Lyapunov's control theory, we introduce offloading policies that balance energy consumption at fog nodes and monetary cost of using the cloud, while ensuring system stability and delay requirements. Results show that our algorithm outperforms baseline solutions, even under high loads and stringent energy requirements, and can be adapted to different goals.

Summary: The Internet of Things (IoTs) has become a crucial part of the 5th Generation (5G) network, accelerating the transition to a digital society. However, the increasing signaling traffic generated by billions of IoT devices has strained the 5G Core network (5GC) control plane. To address this issue, the 3rd Generation Partnership Project (3GPP) proposed a Service-Based Architecture (SBA) for a flexible and scalable cloud-native 5GC. This paper introduces a Message-Level StateLess Design (ML-SLD) to provide a cloud-native 5GC from an architectural standpoint, including innovative mechanisms for servitization and on-demand message forwarding.
