In this paper, we present a partitioning, mapping, and routing optimization framework for energy-efficient VFI (Voltage-Frequency Island) based Network-on-Chip. Unlike the recent work [10] which only performs partitioning together with voltage-frequency assignment for a given mesh network layout, our framework consists of three key VFI-aware components,(More)
In this paper, we propose a novel and global A3MAP (Architecture-Aware Analytic Mapping) algorithm applied to NoC (Networks-on-Chip) based MPSoC (Multi-Processor System-on-Chip) not only with homogeneous cores on regular mesh architecture as done by most previous mapping algorithms but also with heterogeneous cores on irregular mesh or custom architecture.(More)
In this paper, we present an NoC (Networks-on-Chip) router with an SDRAM-aware flow control. Based on a priority-based arbitration, it schedules packets to improve memory utilization and reduce memory latency. Moreover, our multi-scheduling scheme performed by the multiple SDRAM-aware routers helps to achieve better SDRAM performance and save the hardware(More)
Task scheduling and core mapping have a significant impact on the overall performance of network on chip (NOC). In this paper, a unified task scheduling and core mapping algorithm called UNISM is proposed for different NOC architectures including regular mesh, irregular mesh and custom networks. First, a unified model combining scheduling and mapping is(More)
Dysphagia is an important issue in the prognosis of Parkinson’s disease (PD). Although several studies have reported that oropharyngeal dysphagia may be associated with cognitive dysfunction, the exact relationship between cortical function and swallowing function in PD patients is unclear. Therefore, we investigated the association between an(More)
OBJECTIVE Our study aimed to determine whether the short latency afferent inhibition (SAI) response could be associated with the severity of olfactory dysfunction in PD patients. METHODS A total of 71 PD patients and 20 controls were enrolled. All PD patients were classified into 3 groups by the severity of the olfactory deficit. Single-pulse(More)
In this paper, we propose an application-aware networks-on-chip (NoC) design for efficient SDRAM access. In order to provide short latency for priority memory requests with few penalties, a packet is split into several short packets which then are scheduled by the proposed flow controller in a router. Moreover, our NoC design further improves memory(More)
A novel method for in vitro calibration of skin hydration measurements is presented. The method combines gravimetric and electrical measurements and reveals an exponential dependency of measured electrical susceptance to absolute water content in the epidermal stratum corneum. The results also show that absorption of water into the stratum corneum exhibits(More)
Many-core chips interconnected by networks-on-chip (NoC) are increasingly challenged by the tight power consumption constraints. The concept of voltage and frequency island (VFI) which has been recently introduced for achieving fine-grain core-level power management fits well with an NoC design style. This paper will discuss some recent advancement of VFI(More)
OBJECTIVE Recently, arm facilitation has been interested in gait rehabilitation. However, there have been few studies concerning arm facilitation in patients with Parkinson's disease (PD). The aim of our study was to investigate the effect of increasing arm weights on gait pattern in patients with PD. METHODS Twenty-seven patients with PD were enrolled,(More)
