Abstract:

This work presents a highly integrated multi-functional, multi-waveform signal generator which can generate various waveforms, with digital controller inside to adapt embedded and low power applications. The proposed system uses Nios II, a reconfigurable, programmable and optimizable soft-core embedded CPU together with modern EDA tools to accomplish system HW/SW co-design and implementation. Utilizing characteristics of Nios II, we put together core and peripheral logical units that system needs and implant them into a single FPGA chip, then uses the Avalon bus to connect peripheral modules (

We propose a semi-automatic HW/SW codesign flow for low-power and low-cost Neuro-Fuzzy embedded systems. Applications range from fast prototyping of embedded systems to high-speed simulation of Simulink models and rapid design of Neuro-Fuzzy devices. The proposed codesign flow works with different technologies and architectures (namely, software, digital and analog). We have used The Mathworks' Simulink© environment for functional specification and for analysis of performance criteria such as timing (latency and throughput), power dissipation, size and cost. The proposed flow can exploit trade

Abstract:

As many embedded microprocessors are battery driven, low power design is becoming increasingly necessary. In this paper, we proposed hardware-software co-design architecture for low power arithmetic and logic units. By including multiple functional units with the same functions and different speeds, we provide instruction implementations at various power prices. Then, with an assembler level scheduler, we identify and create situations whereby the low-power slow functional units can be utilized. The overall performance is not compromised as no additional stalls are introduced. Simulations show

Therefore, on high-speed not congested networks the bottleneck is no longer the network link but low-processing power network devices. A new ACK optimization algorithm has

The severity of power consumption during parallel BIST of embedded memory cores is growing significantly.

The effectiveness of the row bank-based precharge technique is due to the predictable address sequence during test. In low-power test mode, instead of precharging the entire memory array, only the current accessed row bank is precharged. This will result in signif

Low-frequency noise is difficult to suppress by passive control using a sound absorbing material. Active noise control is expected to be an effective method against low-frequency noise.

Abstract:

In recent years, there has been a desire to improve electricity generation and consumption, to reach sustainability. Technological solutions today allow a rational use of electricity with good overall performance. Traditionally, from production to distribution, electrical energy is AC-supported for compatibility reasons and easy voltage level transformation. However, nowadays most electric loads need DC power to work properly. A single high-efficiency central AC-DC power converter may be advantageous in eliminating several less efficient AC-DC embedded converters, distributed all over a reside

A low-frequency (460 kHz), low-pressure, thermally non-equilibrium, high-density inductively coupled plasma (ICP) has been used to synthesize a novel, advanced photovoltaic material suitable for fabrication of third-generation solar cells. Silicon quantum dots (SQDs) embedded in an amorphous silicon carbide matrix were prepared at a very low substrate temperature of approximately 200°C without any hydrogen dilution. The effect of the radio-frequency (RF) power of the plasma discharge on the morphology and structure of the embedded quantum dots was studied. A brief discussion on the possible me

Abstract:

Low-frequency noise is difficult to suppress by passive control using a sound absorbing material. Active noise control is expected to be an effective method against low-frequency noise. Minimizing the total acoustic power emitted by a sound source causes a zero-control power phenomenon. In the zero-control power phenomenon, the absorption and blowout of sound energy around the control sound source (control sound source) are balanced, and the time average of the control power come into zero. Thus, control power suppression may be able to minimize total acoustic power. Previous studies have assu

Today's power modules are based on DCB (Direct Copper bonded) ceramic substrates. IGBT switches are mounted onto the ceramic and their top side contacts are connected by thick Al wires.

Abstract:

This paper proposes a coordinated centralized/decentralized control designed to concomitantly manage the power factor and mitigate voltage variations at the main feeder of an oil and gas offshore platform. The centralized action (i.e., power factor control) is decoupled from the decentralized one (i.e., voltage support) due to the significant disparity in dynamics of the commands sent to the active front-end variable frequency drives (AFE-VFDs). The AFE-VFDs are embedded with a proposed V-Q inverse droop curve, while being remotely coordinated by a central controller using a low-bandwidth comm
