- In this paper, we present novel network interface architecture for on-chip networks to increase memory parallelism and to improve the resource utilization. The proposed architecture exploits AXI transaction based protocol to be compatible with existing IP cores. Experimental results with synthetic test case demonstrate that the proposed architecture outperforms the conventional architecture in term of latency.

- Adopting the bio-inspired system architecture, a hierarchical agent monitoring NoC design method is proposed. Based on circuit conditions traced at the run-time, system settings including resource utilization and power supplies are configured hierarchically and adaptively at each architecture level by corresponding agents. This methodology provides systematic design approaches to VLSI circuits under the influence of unpredictable variations and stringent power constraints. Each level of agents autonomously monitor their local components while being supervised by their higher level counterparts. In this manner, the overall performance and efficiency can be maximized for systems of any scale. The feasibility and innovation of this methodology are explained elaborately with low-power optimization and fault-tolerance services, and architectural alternative analysis on the regular NoC platform is presented. An FFT study case demonstrates the functional effectiveness and flexibility of agent-monitored adaptive system configuration in case of component failures.

Konferensbidrag (refereegranskat)abstract
- Hierarchical Agent Architecture is proposed to provideonline monitoring services to NoC-based systems. Basedon circuit conditions traced at the run-time, system settingsare monitored adaptively by agents at each architectural level.This monitoring approach partitions various online diagnosticand management services onto hierarchical implementation levelsso as to provide scalability and variability for large-scale NoCdesign. This paper explains the monitoring interaction betweenagent levels, and focuses on system optimization alternativeshandled by different agent levels. It further quantitatively analyzesthe feasibility and design alternatives in monitoring communicationinterconnection upon regular tile-based NoC layout.Though still under intensive research, the proposed architectureis endowed with promising potential for highly-integrated NoCdesign.

- Network-on-Chip (NoC) is a promising architecturein the many-core on-chip systems. A hierarchical agentbased NoC architecture is proposed which enables the NoCto autonomously adjust itself, and provide maximum powerefficiency, fault/variation tolerance and system flexibility. Agentsare software or hardware components which monitor and controlthe system at different granularity. Via the joint efforts andinteractions of agents at all levels of the architecture, systemoptimization can be achieved at the runtime. Agent hierarchy,mapping of agents on regular NoC platforms and the functionpartition among the agents are elaborately discussed.Runtime power management with various Dynamic Voltageand Frequency Scaling (DVFS) techniques is analyzed on thehierarchical agent based NoC platform. Conventional powermonitoring techniques can be flexibly incorporated into the functionsof specific levels of agents. Network condition is observed bythe agents at the runtime, and the power supplies are adjusted atdifferent granularity accordingly. This paper describes the systemarchitectures of two adaptive schemes, with efficient and feasiblealgorithms presented. Quantitative experiments demonstrate thatthey achieve superior power efficiency comparing with the basicarchitecture without any runtime configuration, while different tradeoffs are applied dependent on the monitoring granularity.

Hierarchical agent based NoC with dynamic online services

Konferensbidrag (refereegranskat)abstract
- As the size of NoCs increases, power consumption and fault/variation tolerance have become two of the most crucial problems for system designers. To address these problems, we propose a NoC architecture based on a hierarchy of monitoring agents. By tracing the circuit properties at run time, the agents at different architectural levels are able to monitor and control over the whole NoC platform. This monitoring approach partitions various online diagnostic and management services onto hierarchical implementation levels so as to provide scalability and variability for large-scale NoC design. This paper explains the monitoring interaction between agent levels, and focuses on system optimization alternatives handled by different agent levels. It further quantitatively analyzes the feasibility and design alternatives in monitoring communication interconnection upon regular tile-based NoC layout.

- An RFID antenna with integrated humidity sensor and calibration functionality for wireless sensor network is proposed. The antenna is composed of series and shunt stubs for impedance matching and reliability for near-field communication. The innovative ladder contour structure plays the key role for humidity sensing, and sensor calibration. The quadrangular end-tip loading is employed to offer capacitance and stability for far-field communication. The prototypes of the antenna are fabricated and tested: antenna effectively senses the ambient humidity levels while demonstrating stable behavior for RFID communication. The antenna has a compact size of 1 × 10cm for 902-928 MHz RFID band.

- Early warning score (EWS) is a prediction method to notify caregivers at a hospital about the deterioration of a patient. Deterioration can be identified by detecting abnormalities in patient’s vital signs several hours prior the condition of the patient gets life-threatening. In the existing EWS systems, monitoring of patient’s vital signs and the determining the score is mostly performed in a paper and pen based way. Furthermore, currently it is done solely in a hospital environment. In this paper, we propose to import this system to patients’ home to provide an automated platform which not only monitors patents’ vital signs but also looks over his/her activities and the surrounding environment. Thanks to the Internet-of-Things technology, we present an intelligent early warning method to remotely monitor in-home patients and generate alerts in case of different medical emergencies or radical changes in condition of the patient. We also demonstrate an early warning score analysis system which continuously performs sensing, transferring, and recording vital signs, activity-related data, and environmental parameters.

- Early warning score (EWS) is an approach to detect the deterioration of a patient. It is based on a fact that there are several changes in the physiological parameters prior a clinical deterioration of a patient. Currently, EWS procedure is mostly used for in-hospital clinical cases and is performed in a manual paper-based fashion. In this paper, we propose an automated EWS health monitoring system to intelligently monitor vital signs and prevent health deterioration for in-home patients using Internet-of-Things (IoT) technologies. IoT enables our solution to provide a real-Time 24/7 service for health professionals to remotely monitor inhome patients via Internet and receive notifications in case of emergency. We also demonstrate a proof-of-concept EWS system where continuous reading, transferring, recording, and processing of vital signs have been implemented.
