Phase Change Memory (PCM) has emerged as a viable alternative to traditional DRAM memories especially in real-timeembeddedsystems, due to their higher density and lower leakage power dissipation. However, PCM comes with its own drawbacks. Although, the performances of DRAM and PCM are comparable for memory reads, PCM is about three times slower in terms of write latency, and suffers from significantly lower write endurance. The high write latency of PCM may be detrimental to delivered QoS and may lead to deadline misses in real-timesystems. To circumvent the problem, this paper proposes a novel memory scheduling scheme which employs separate write request buffer in order to prioritize reads over writes. The read requests are scheduled using an urgency based scheduler where urgency depends on allowable response times of tasks. The write requests are serviced when there are no pending reads using a similar urgency based scheduler as used for read requests. Experimental evaluation using standard benchmarks reveal that the proposed scheme is able to achieve better normalized QoS compared to existing scheduling techniques for PCM and comparable access latencies with respect to DRAM.

With the technological developments of recent years, the concept of the "Smart Classroom" has gained in importance and is increasingly becoming a plausible reality. This refers to a classroom in which real-time data collection facilitates decision-making to improve teaching and learning processes. This article presents a proposal for the smart classroom infrastructure that utilises based on the Internet of Things and Cognitive and Intelligent systems. It consists of a number of perception units that focus on monitoring environmental variables such as light, air quality and noise, as well as variables related to the actors involved (students and teachers), especially those about emotions (which play a crucial role in educational processes). The information extracted from the data is stored and analysed by the classroom agent, which provides teachers with relevant information and suggestions in a timely manner. It is important to further develop our smart classroom infrastructure and test it in real environments to evaluate its potential and benefits in terms of the teaching and learning process, as well as to identify possible drawbacks and obstacles to implementation.

As datacenters become the new computing platform, integrating server-centric distributed systems into modern network hardware is gaining interest under the diminishing Moore's law. Researchers want to build reusable primitives that can take advantage of modern network hardware and offload common system components of a broad range of applications. In this paper, we present Mostly Reliable Totally Ordered Multicast, a reusable network primitive that can embed reliable group communication into the network. MRTOM is a network-centric approach that handles message replication, ordering, and reliable delivery using a network fast path, freeing server CPUs for application logic. MRTOM can be implemented in the programmable switches and edge interfaces (e.g., SmartNICs), significantly reducing network traffic compared to the existing approaches and improving job finish time amid packet loss. With MRTOM, we were able to accelerate multiple high-performance applications whose fast path can be totally offloaded into the network. For example, a Paxos application, MRTOM-Paxos, achieves > 1,100,000 transactions/secs and 23 mu s minimum latency. A replicated key-value store, MRTOM-KV, also shows significant latency reduction with eBPF/XDP in the Linux Kernel, which is further improved by offloading into SmartNICs.

The popularity of home automation has been rapidly increasing in recent years due to higher affordability and simplicity. Today, IoT platforms are vertically oriented and often still closed systems. To enable interoperable interaction with those platforms, we present a home automation system based on open standards enabling IoT peer-to-peer communications. The multiple platforms in multiple IoT applications have been connected using this system. The idea is to enable an open ecosystem by considering standardized communication interfaces to allow real-time data exchanges across platforms and systems. In this work, we perform smart home prototyping and enable device interaction for data sharing and real-time accessibility using any device.
With the rapid growth of Internet of Things (IoT) devices, the explosive increase in data volume poses significant challenges for traditional embeddedsystems in handling massive data and managing multiple transaction...

Venturing deeper into the outer-space has always extended the reaches of our intellect, "the farther we go, the more we know." It has not only fostered our scientific and technological advancements but has also made us love and cherish our cozy abode in this vast universe. The knowledge gained from space missions in the guise of measurement data, is of no use if not accurately communicated back to the Earth. This work, for the first time, proposes a new VLSI architecture of turbo encoder for deep space communication systems that has been designed as per the contemporary standard specifications, recommended by CCSDS. The design has been implemented on FPGA where our turbo encoder, operates at the maximum clock frequency of 27 MHz. In addition, this paper also proposes a novel technique with an implementable architecture for simultaneous puncturing and serialization of the encoded bits, providing a 50% reduction in the overall latency over the conventional puncturing and serialization technique, consequently, aiding to achieve real-time operating capability for the designed turbo encoder system.
