In this design, we propose a virtual electronic dart system which contains a microcontroller, tri-axis accelerometer and Bluetooth module. The players only need to hold the virtual electronic dart and swing it in the air. The controller will transmit the space coordinates of the virtual electronic dart to the smartphone that calculates the hit location of the dartboard from the flying path of the...
An independent-gate FinFET can operate in three modes: SG (shorted-gate), IG (independent-gate), and LP (low-power) modes, and thus a FinFET-based circuit offers a rich design space to explore. In this paper, we explore the best configuration for the FinFET-based TCAM cell. Compared with the base TCAM cell, the proposed TCAM cell Config-LPSG-1 can reduce the power dissipation of the TCAM by 35%, and...
Multiply-accumulator (MAC) is the central unit used in digital signal processors (DSP) that are now widely found in many consumer electronic devices. With current emphasis on minimizing operating power and yet maximizing computation performance for DSPs, efficient MAC architecture with low power consumption and high computation performance is hence desired. This paper proposes a low power pipelined...
Virtualization has recently become popular in the embedded-systems area. In order to apply virtualization techniques on embedded-systems, we need a hypervisor that provides a software virtualization environment. A hypervisor scheduler assigns virtual cores in a virtual machine to physical cores. Since traditional load-balanced scheduling strategy is not aware of the asymmetry of cores, its deployment...
The paper proposed an optimal household load scheduling framework for home energy management systems to minimize the electricity bill and maximize users' comfort. The framework considers not only renewable energy and demand response requirement but also characteristics of home appliances and comfort level. Simulation results demonstrates its effectiveness.
The control method of elevator system for peak power cut maintaining service performance has been proposed. Even if the method is optimal for the whole system, it is not always suitable for comfort of individual passenger. The paper describes the modeling and simulation of individual passenger transportation in elevator based on Mark Flow Graph.
Power distribution protocol among power plants and consumers in power packet networks is proposed. According to this protocol, power packets are transmitted multipoint-to-multipoint simultaneously. Each power plant decides its power transmission destination depending on consumer demands and distances to them. The power transmission procedure is triggered by an occurring of a consumer demand. The power...
Recently, eMMC is widely being used in mobile devices because of its characteristics such as low cost, small size, and low power consumption. In this paper, we analyze features of eMMC based on commands such as Trim, Discard, and Background to investigate how do commands affect the random write performance and lifetime of the NAND flash memory. Also, we propose a method that uses the Background command...
