Unix Unleashed, Third Edition is written with the power user and system administrator in mind. This book will help the reader understand the nuances of the major Unix variants including SVR4, HP-UX, Solaris, AIX, BSD, IRIX, SunOS, and Linux. It will help the reader decide which Unix shell works best for their particular situation. Other topics such as Kernel Configuration, Networking, User Administration, and File Management are covered extensively for the administrator who wants a variety of options to choose from for best performance. The book also provides in-depth coverage of configuring and optimizing mail, DNS, HTTP and other services many companies deploy across their intranet and on the Internet

本例展示了如何利用外設(shè)TIM2來產(chǎn)生四路頻率不同的信號。 TIM2時鐘設(shè)置為36MHz，預(yù)分頻設(shè)置為2，使用輸出比較-翻轉(zhuǎn)模式（Output Compare Toggle Mode）。 TIM2計數(shù)器時鐘可表達(dá)為：TIM2 counter clock = TIMxCLK / (Prescaler +1) = 12 MHz 設(shè)置TIM2_CCR1寄存器值為32768，則CC1更新頻率為TIM2計數(shù)器時鐘頻率除以CCR1寄存器值，為366.2 Hz。因此，TIM2通道1可產(chǎn)生一個頻率為183.1 Hz的周期信號。 同理，根據(jù)寄存器TIM2_CCR2 、TIM2_CCR3和 TIM2_CCR4的值，TIM2通道2可產(chǎn)生一個頻率為366.3 Hz的周期信號；TIM2通道3可產(chǎn)生一個頻率為732.4 Hz的周期信號；TIM2通道4可產(chǎn)生一個頻率為1464.8 Hz的周期信號。 可以通過示波器觀察各路輸出

Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features: * Creates a virtual encrypted disk within a file and mounts it as a real disk. * Encrypts an entire partition or storage device such as USB flash drive or hard drive. * Encrypts a partition or drive where Windows is installed (pre-boot authentication). * Encryption is automatic, real-time (on-the-fly) and transparent. * Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS. Further information regarding features of the software may be found in the:http://www.truecrypt.org/

采用VHDL語言設(shè)計一個4通道的數(shù)據(jù)采集控制模塊。系統(tǒng)的功能描述如下： 1.系統(tǒng)主時鐘為100 MHz。 2.數(shù)據(jù)為16位-數(shù)據(jù)線上連續(xù)2次00FF后數(shù)據(jù)傳輸開始。 3.系統(tǒng)內(nèi)部總線寬度為8位。 4.共有4個通道（ch1、ch2、ch3、ch4），每個通道配備100 Bytes的RAM，當(dāng)存滿數(shù)據(jù)后停止數(shù)據(jù)采集并且相應(yīng)通道的狀態(tài)位產(chǎn)生報警信號。 5.數(shù)據(jù)分為8位串行輸出，輸出時鐘由外部數(shù)據(jù)讀取電路給出。 6.具備顯示模塊驅(qū)動功能。由SEL信號設(shè)置顯示的通道，DISPLAY信號啟動所選通道RAM中數(shù)值的顯示過程。數(shù)值順次顯示一遍后顯示結(jié)束，可以重新設(shè)定SEL的值選擇下一個通道。模塊數(shù)據(jù)線為8位，顯示器件為4個8段LED。 7.數(shù)據(jù)采集模式如下：單通道采集（由SEL信號選擇通道），多通道順次采集（當(dāng)前通道采滿后轉(zhuǎn)入下一通道），多通道并行采集（每通道依次采集一個數(shù)據(jù)）。模式由控制信號MODE選擇，采集數(shù)據(jù)的總個數(shù)由NUM_COLLECT給出。 8.數(shù)據(jù)采集過程中不能讀取，數(shù)據(jù)讀取過程中不能采集
