Device-to-device(D2D) communications are now considered as an integral part of future 5G networks which will enable direct communication between user equipment (UE) without unnecessary routing via the network infrastructure. This architecture will result in higher throughputs than conventional cellular networks, but with the increased potential for co-channel interference induced by randomly located cellular and D2D UEs.

The challenges associated with the design and implementation of Electro- static Discharge (ESD) protection circuits become increasingly complex as technology is scaled well into nano-metric regime. One must understand the behavior of semiconductor devices under very high current densities, high temperature transients in order to surmount the nano-meter ESD challenge. As a consequence, the quest for suitable ESD solution in a given technology must start from the device level. Traditional approaches of ESD design may not be adequate as the ESD damages occur at successively lower voltages in nano-metric dimensions.

The continuous progress in modern power device technology is increasingly supported by power-specific modeling methodologies and dedicated simulation tools. These enable the detailed analysis of operational principles on the the device and on the system level; in particular, they allow the designer to perform trade- off studies by investigating the operation of competing design variants in a very early stage of the development process. Furthermore, using predictive computer simulation makes it possible to analyze the device and system behavior not only under regularoperatingconditions, but also at the rim of the safe-operatingarea and beyond of it, where destructive processes occur that limit the lifetime of a power system.

隨著圖像處理技術(shù)的不斷發(fā)展,圖像處理技術(shù)在國(guó)民經(jīng)濟(jì)和社會(huì)生活的各個(gè)方面都得到了廣泛的運(yùn)用。與此同時(shí),人們對(duì)圖像處理的要求也越來(lái)越高。傳統(tǒng)的數(shù)字圖像處理器件主要有專用集成芯片(Application Specific Integrated Circuit)和數(shù)字信號(hào)處理器(Digital Signal Process)。進(jìn)入20世紀(jì)以來(lái),伴隨著半導(dǎo)體技術(shù)的發(fā)展,現(xiàn)場(chǎng)可編程門陣列FPGA以其應(yīng)用靈活、集成度高、功能強(qiáng)大、設(shè)計(jì)周期短、開(kāi)發(fā)成本低的特點(diǎn),越來(lái)越多地被應(yīng)用在圖像處理領(lǐng)域。大量實(shí)踐證明,F(xiàn)PGA的并行處理能力與流水線作業(yè)能顯著地提高圖像處理的速度,因此基于FPGA的圖像處理系統(tǒng)有著廣闊的發(fā)展前景。 本文研究的是一個(gè)在嵌入式視頻監(jiān)控系統(tǒng)下的圖像預(yù)處理子系統(tǒng)。首先實(shí)現(xiàn)了一個(gè)通用可重復(fù)配置的圖像處理算法研究硬件平臺(tái),完成圖像的采集、接收、處理、存儲(chǔ)、輸出等功能。由于FPGA本身具有完全的可重復(fù)配置性,所以該架構(gòu)的硬件平臺(tái)可以很方便的升級(jí)和重復(fù)配置。其次在該平臺(tái)上,本文使用Verilog HDL硬件語(yǔ)言在FPGA芯片上實(shí)現(xiàn)了多種圖像預(yù)處理算法。在實(shí)現(xiàn)過(guò)程中,為了充分發(fā)揮FPGA在并行處理方面的強(qiáng)大功能,本文對(duì)算法做了一定的改進(jìn),使其盡量能使用并行處理的方式來(lái)完成。實(shí)驗(yàn)結(jié)果表明,本圖像預(yù)處理系統(tǒng)能在毫秒級(jí)高速地完成多種圖像算法,完全能夠滿足視頻監(jiān)控系統(tǒng)50幀/秒的輸出要求。 最后根據(jù)視頻監(jiān)控系統(tǒng)在實(shí)際運(yùn)用中出現(xiàn)的噪聲類型多樣化的情況,我們?cè)O(shè)計(jì)了一種基于反饋理論的圖像處理效果控制模塊。該模塊能通過(guò)對(duì)處理后圖像峰值信噪比(PSNR)的分析,控制FPGA對(duì)下一幅圖像的噪聲采用更有針對(duì)性的圖像處理方法。
