The integration of both fronthaul and backhaul into a single transport network (namely, 5G-Crosshaul) is envisioned for the future 5G transport networks. This requires a fully integrated and unified management of the fronthaul and backhaul resources in a cost-efficient, scalable and flexible way through the deployment of an SDN/NFV control framework. This paper presents the designed 5G-Crosshaul architecture,...
Cloud-based Radio Access Network (C-RAN) is a promising architecture for future cellular networks, in which Baseband Units (BBUs) are placed at a centralized location, with capacity-constrained fronthaul connected to multiple distributed Remote Radio Heads (RRHs) that are far away from the BBUs. The centralization of signal processing enables the flexibility for coordinated multi-point transmission...
Today's supercomputers are moving towards deployment of many-core processors like Intel Xeon Phi Knights Landing (KNL), to deliver high compute and memory capacity. Applications executing on such many-core platforms with improved vectorization require high memory bandwidth. To improve performance, architectures like Knights Landing include a high bandwidth and low capacity in-package high bandwidth...
The envisioned Internet of Things (IoT) will involve a massive deployment of objects connected through wireless cells. While commercial solutions are already available, the fundamental limits of such networks in terms of node density, achievable rates or reliability are not known. To address this question, this paper uses a large scale Multiple Access Channel (MAC) to model IoT nodes randomly distributed...
Content Centric Networking (CCN) is an important aspect of the Future Internet Architecture. CCN investigates the evolution from current host-centric network architecture of IP to data centric networking architecture. This paper aims at demonstrating the integration of Named Data Networking (NDN) mechanism, an instantiation of CCN, in previously developed DataTweet Internet of Things (IoT) architecture...
Signed binary multiplication is the essential part of all digital processing needs. The digital processing is inseparable part in microprocessor, microcontroller, digital image processing, data manipulation, etc. In this paper, a method to generate the partial products which are generated in the multiplication process is being proposed, in order to reduce the computational efforts in the multiplication...
This summary reports the workshops accepted in the 1st International Conference on Software Architecture (ICSA 2017), held by Chalmers University at Gothenburg (Sweden). We gather the description of current and new research trends in different software architecture topics to provide a wide view to researchers and practitioners about the current status and trends in the field. ICSA is a premier software...
On behalf of the advisory committee of COOL Chips 20, I extend greetings to each of the conference attendees. This year we celebrate the 20th anniversary of this conference series that is part of the premier conference series on microprocessor architecture and technology and software. Today we have issues in cloud computing, cyber security, IoT, Big Data, and artificial intelligence, especially deep...
Field polynomial division can be found in applications such as error detection and data encoding for digital communication systems. In addition, it implements the extended Euclidean algorithm (EEA), which can be used as the field inversion building block of elliptic curve cryptosystem. The unpredictability of the iterative algorithm of polynomial division in the EEA-Based field inversion results in...
This paper is an exploratory study on architects' attitudes towards risk and its influences on the architectural decision-making process. A classification of architects' attitude to risk-taking has been developed on the basis of Fowler's Technical Debt Quadrants. The core proposition of the paper is that the well-established concept of 'risk appetite' can be equally well applied to characterise and...
Software architecting is about making decisions that have system-wide impact and that shape software product and process alike. While researchers and practitioners have tried to define and scope the role of the architect, social and organizational impacts on the architect and the architecting process are often neglected. The SODA workshop focuses on the social and organizational dimensions in which...
Large software companies need a well-managed Software Architecture to support continuous and fast delivery of customer value both in the short and long term. However, this can be hindered if both evolution and maintenance of existing systems are hampered by Architectural Technical Debt. To avoid the accumulation and the costly consequences of ATD, it is critical that the responsibilities to minimize...
The Internet of Things (IoT) includes billions of things, i.e., connected objects and devices that are heterogeneous, distributed, and possibly intelligent and run applications and services from the Internet of Services (IoS). Things span, for instance, RFID tags, sensors, computers, plants, lamps, autonomous robots, and self-driving vehicles. Often, things are connected through heterogeneous platforms...
Time mode signal processing (TMSP) is the implementation of analog signal processing functions using the most basic element available, namely, propagation delay. Moreover, a time to digital converter (TDC), an important block of time mode circuits, could be used to convert the time difference between two edges of two signals into a sequence of digital numbers. In this paper, a new time mode SerDes...
Feature fusion methods have been demonstrated to be effective for many computer vision based applications. These methods generally use multiple hand-crafted features. However, in recent days, features extracted through transfer leaning procedures have been proved to be robust than the hand-crafted features in myriad applications, such as object classification and recognition. The transfer learning...
Software architecture has many definitions. One widely accepted definition of software architecture is that it is a composition of a set of architectural design decisions. Hence, designing a software architecture is a decision-making process. Agile methods drastically changed the way of designing a software architecture. In projects using agile methods (e.g. Scrum), making architectural design decisions...
