可編程邏輯芯片特別是現場可編程門陣列(Field-Programmable Gate Array，FPGA)芯片的快速發(fā)展，使得新的芯片能夠根據具體應用動態(tài)地調整結構以獲得更好的性能，這類芯片稱為動態(tài)可重構FPGA芯片(Dynamically ReconfigurableFPGA，DRFPGA)。然而，使用這類芯片構建的可重構系統(tǒng)在實際應用前還有許多問題需要解決。一個基本的問題就是動態(tài)可重構FPGA芯片中的可重構功能單元(Reconfigurable Functional Unit，RFU)的模塊布局問題和模塊間的布線問題。 本文從基本的FPGA芯片結構和CAD算法談起，介紹了可重構計算的概念，建立了可重構計算系統(tǒng)模型和動態(tài)可重構FPGA芯片模型，在此模型上提出一個基于劃分和時延驅動的在線布局算法，和一個基于Pathfinder協(xié)商擁塞算法的布線算法，來解決動態(tài)可重構FPGA芯片的布局和布線問題。由硬件描述語言(Hardware Description Language，HDL)描述的電路首先被劃分成有限數目的層，然后將這些電路層布局到芯片的每一層，同時確保關鍵路徑的時延最小。實驗結果表明，布局算法與傳統(tǒng)的布局算法(或者文獻[37]中的算法)相比，在時延上平均減少27％，在線長上平均減少34％(或者11％)，在運行時間上平均減少42％(或者97％)。布線算法與傳統(tǒng)的布線算法相比，能夠將線長降低26％，將水平通道寬度降低27％，顯示出較高的性能。

螺旋槳PID控制 In response to constant pressure to design more efficient, faster, smaller, and better systems, engineers are constantly looking for ways to improve existing designs or replace them with better ones. Facing large fuel costs, the aerospace industry in particular has been researching alternative designs to increase fuel efficiency and performance. One such alternative is the development of Reconfigurable aircraft wings. These wings would be able to adapt to the current environment increasing lift or reducing drag when appropriate.

本文討論半導體產品特征循環(huán)及其對產品技術發(fā)展的 啟示 。分析指出，半導體產品的主特征一直遵循著“通用” 與“專用”交替發(fā)展，每十年波動一次，目前正進入以嵌入 式可編程SoC為特征的專用（可稱為專用可編程產品，ASPP波動階段。同時還指出了牧村浪潮與我們提出的“半導體產品特征循環(huán)”的共同點與分歧。根據預測，半導體產品將在ASPP發(fā)展中，向用戶可重構片上系統(tǒng)（U-SoC, User-Reconfigurable SoC）方向發(fā)展，進入傳統(tǒng)硅微電子技術的最后一次通用波動。文中最后分析了可重構計算的發(fā)展現狀和存在的問題，以及今后的發(fā)展方向。

The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of Reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.

Digital mobile wireless communication and the Internet have undergone a fantastic growth in the last few years and, despite originating from two different worlds, they are converging. This convergence corresponds to the evolution of mobile systems towards the highest broadband data transmissions (GSM, EDGE/GPRS, UMTS then HSDPA), while the computing world gets equipped with wireless technologies such as Wi-Fi or Wi-Max.

Until the mid-1990s most readers would probably not have even come across the term soft- ware defined radio (SDR), let alone had an idea what it referred to. Since then SDR has made the transition from obscurity to mainstream, albeit still with many different understandings of the terms – software radio, software defined radio, software based radio, Reconfigurable radio.

Software Radio (SR) is one of the most important emerging technologies for the future of wireless communication services. By moving radio functionality into software, it promises to give flexible radio systems that are multi-service, multi- standard, multi-band, Reconfigurable and reprogrammable by software. Today’s radios are matched to a particular class of signals that are well defined bytheircarrierfrequencies,modulationformatsandbandwidths.Aradiotransmitter today can only up convert signals with well-defined bandwidths over defined center frequencies, while, on the other side of the communication chain, a radio receiver can only down convert well-defined signal bandwidths, transmitted over specified carrier frequencies.

This book is concerned with integrated circuits and systems for wireless and mobile communications. Circuit techniques and implementation of Reconfigurable low-voltage and low-power single-chip CMOS transceivers for multiband and multi- mode universal wireless communications are the focus of the book. Applications encompass both long-range mobile cellular communications (GSM and UMTS) and short-range wireless LANs (IEEE802.11 and Bluetooth). Recent advances in research into transceiver architecture, RF frontend, analogue baseband, RF CAD and automatic testing are reported.
