TL;DR: Targeted mainly at DSP-type operations, the Colt integrated circuit -- a prototype wormhole RTR device -- compares favorably to contemporary DSP alternatives in terms of silicon area consumed per unit computation and in computing performance.
Abstract: Wormhole run-time reconfiguration (RTR) is an attempt to create a refined computing paradigm for high performance computational tasks. By combining concepts from field programmable gate array (FPGA) technologies with data flow computing, the Colt/Stallion architecture achieves high utilization of hardware resources, and facilitates rapid run-time reconfiguration. Targeted mainly at DSP-type operations, the Colt integrated circuit -- a prototype wormhole RTR device -- compares favorably to contemporary DSP alternatives in terms of silicon area consumed per unit computation and in computing performance. Although emphasis has been placed on signal processing applications, general purpose computation has not been overlooked. Colt is a prototype that defines an architecture not only at the chip level but also in terms of an overall system design. As this system is realized, the concept of wormhole RTR will be applied to numerical computation and DSP applications including those common to image processing, communications systems, digital filters, acoustic processing, real-time control systems and simulation acceleration.

TL;DR: A design flow to efficiently map multiple multi-core applications on a dynamically reconfigurable SoC is presented and is actually able to extract similarities among the applications, as it achieves an average improvement in terms of reconfiguration latency with respect to a communication-oriented approach.
Abstract: Nowadays, multi-core systems-on-chip (SoCs) are typically required to execute multiple complex applications, which demand a large set of heterogeneous hardware cores with different sizes. In this context, the popularity of dynamically reconfigurable platforms is growing, as they increase the ability of the initial design to adapt to future modifications. This paper presents a design flow to efficiently map multiple multi-core applications on a dynamically reconfigurable SoC. The proposed methodology is tailored for a reconfigurable hardware architecture based on a flexible communication infrastructure, and exploits applications similarities to obtain an effective mapping. We also introduce a run-time mapper that is able to introduce new applications that were not known at design-time, preserving the mapping of the original system. We apply our design flow to a real-world multimedia case study and to a set of synthetic benchmarks, showing that it is actually able to extract similarities among the applications, as it achieves an average improvement of 29% in terms of reconfiguration latency with respect to a communication-oriented approach, while preserving the same communication performance.

TL;DR: In this paper, a reconfigurability measurement process based on axiomatic design knowledge base and the design structure matrix has been developed to provide quantitative measures of reconfiguration potential and ease.
Abstract: In recent years, the fields of reconfigurable manufacturing systems, holonic manufacturing systems, and multi-agent systems have made technological advances to support the ready reconfiguration of automated manufacturing systems. While these technological advances have demonstrated robust operation and been qualitatively successful in achieving reconfigurability, limited effort has been devoted to the measurement of reconfigurability in the resultant systems. Hence, it is not clear (1) to which degree these designs have achieved their intended level of reconfigurability, (2) which systems are indeed quantitatively more reconfigurable and (3) how these designs may overcome their design limitations to achieve greater reconfigurability in subsequent design iterations. Recently, a reconfigurability measurement process based upon axiomatic design knowledge base and the design structure matrix has been developed. Together, they provide quantitative measures of reconfiguration potential and ease. This paper now builds upon these works to provide a set of composite reconfigurability measures. Among these are measures for the key characteristics of reconfigurability: integrability, convertibility, and customization, which have driven the qualitative and intuitive design of these technological advances. These measures are then demonstrated on an illustrative example followed by a discussion of how they adhere to requirements for reconfigurability measurement in automated and intelligent manufacturing systems.

01 Jan 2008TL;DR: In this article, a comprehensive treatment of ROADM and their application in WDM transmission systems and networks, comprising a review of various RoADM technologies and architectures, analyses of their routing functionalities and economic advantages, and considerations of design features and other requirements.
Abstract: Publisher Summary Subsystem and system vendors are rapidly developing and producing reconfigurable optical add/drop multiplexers (ROADMs), and carriers are installing and deploying them in their networks. This chapter is a comprehensive treatment of ROADMs and their application in WDM transmission systems and networks, comprising a review of various ROADM technologies and architectures, analyses of their routing functionalities and economic advantages, and considerations of design features and other requirements. The complex interplay between ROADM properties and optical transmission has also been explored, including a detailed discussion of static and dynamic channel power control. ROADMs enable an automated and transparent network capable of rapid reconfiguration. To fully realize this vision within the growing global communication fabric, transmission systems must be capable of dealing with continual changes, including power transients and varying transmission conditions. Network management systems must solve complex problems in routing and wavelength blocking, path verification, and more as the photonic layer assumes some of the tasks previously handled by higher layers. Advanced ROADM functionality, such as colorless add/drop ports, steerable transponders, and adaptive passbands, will be increasingly sought after, as will new and better solutions for signaling, network management, and mesh transmission. By meeting these challenges, the optical R&D community will help address the world's need for flexible, economical, and scalable networks.

TL;DR: Network reconfiguration, together with the incorporation of battery energy storage systems (BESS), facilitates the integration of renewable power and enhances the loadability of the system, leading to prolonged utilization of the existing equipment.
Abstract: In the paradigm of the increasing trend towards decarbonisation, the use of sustainable renewable energy is widely recommended. Network reconfiguration, together with the incorporation of battery energy storage systems (BESS), facilitates the integration of renewable power and enhances the loadability of the system, leading to prolonged utilization of the existing equipment. Optimized allocation of PV-DG and BESS is implemented using particle swarm optimization (PSO) in the present work. Dynamic hourly and static seasonal reconfiguration with optimally allocated PV-DG and BESS is presented. Moreover, static annual reconfiguration, followed by the optimal apportionment of distributed resources, is achieved. The reconfiguration objectives considered are loss minimization as well as voltage, and loadability improvement. Hourly and seasonal variations in load and PV-DG generated power are taken into account. Additionally, ‘P’ and ‘PQV’ buses are incorporated in the load flow algorithm used in reconfiguration to facilitate remote voltage regulation. A comparison of the net annual energy savings is made among the three types of reconfiguration for three scenarios, namely, a system with PV-DG only, a system with PV-DG and BESS, and a system with PV-DG, BESS and P and PQV buses.
