This simple SDI Notepad-like application demonstrates how, taking advantage of the MFC support for Unicode, to Turkmenize labels of the specified menu items. Actually, Turkmen is not supported by Windows 2000, therefore, to create such resources as menu so that strings in Turkmen could be displayed I had to invent an additional technique 這是一個(gè)與記事本類似的簡單的SDI應(yīng)用程序，演示了怎樣使用MFC來支持 Unicode，對(duì)指定的菜單條目進(jìn)行Turkmenize標(biāo)簽化。實(shí)際上，Windwos 2000并不支持Turknen,因此,創(chuàng)建了那些菜單資源以便那些字符串可以在Turknen中顯示,為此我必須開發(fā)其它的技術(shù)。 來源: http://www.codeguru.com/advancedui/SDI_Note.html

The running time of quicksort can be improved in practice by taking advantage of the fast
running time of insertion sort when its input is “nearly” sorted. When quicksort is called on a
subarray with fewer than k elements, let it simply return without sorting the subarray. After the
top-level call to quicksort returns, run insertion sort on the entire array to finish the sorting process.

信息技術(shù)的不斷發(fā)展,對(duì)信息的安全提出了更高的要求.在應(yīng)用公鑰密碼體制的時(shí)候,對(duì)密鑰長度要求越來越大,處理的速度要求越來越快.而基于橢圓曲線離散對(duì)數(shù)問題的橢圓曲線密碼體制,因其每比特最大的安全性,受到了越來越廣泛的注意.橢圓曲線密碼體制(ECC:Elliptic Curve Cryptosystem)的快速實(shí)現(xiàn)也成為一個(gè)關(guān)注的方面.該文按照確定有限域、選取曲線參數(shù)、劃分結(jié)構(gòu)模塊、優(yōu)化模塊算法、實(shí)現(xiàn)模塊設(shè)計(jì),驗(yàn)證模塊功能的順序進(jìn)行書寫.為了硬件實(shí)現(xiàn)上的方便,設(shè)計(jì)選擇了含有Ⅱ型優(yōu)化正規(guī)基的伽略域GF(2191),并在該域上構(gòu)造了隨機(jī)的橢圓曲線.根據(jù)層次化、結(jié)構(gòu)化的設(shè)計(jì)思路,將橢圓曲線上的標(biāo)量乘法運(yùn)算劃分成兩個(gè)運(yùn)算層次:橢圓曲線上的運(yùn)算和有限域上的運(yùn)算.模塊劃分之后,利用自底向上的設(shè)計(jì)思路,主要針對(duì)有限域上的乘法運(yùn)算進(jìn)行了重要的改進(jìn),并對(duì)加法群中的標(biāo)量乘運(yùn)算的算法進(jìn)行了分析、證明,以達(dá)到面積優(yōu)化和快速執(zhí)行的效果.具體設(shè)計(jì)中,采用硬件描述語言Verilog HDL,在Mentor Graphics公司出品的FPGA advantage平臺(tái)上進(jìn)行電路設(shè)計(jì).完成了各個(gè)模塊的設(shè)計(jì)輸入和仿真.設(shè)計(jì)選用了Altera公司的APEX Ⅱ系列器件,利用第一方軟件Quartus Ⅱ 2.2進(jìn)行綜合、布局、布線和時(shí)序仿真.文中給出了橢圓曲線上的點(diǎn)加、倍點(diǎn)和標(biāo)量乘法模塊的具體設(shè)計(jì)結(jié)構(gòu)框圖.并且根據(jù)橢圓曲線的標(biāo)量乘特點(diǎn),提出了合適的驗(yàn)證方案.該設(shè)計(jì)完成了橢圓曲線上的標(biāo)量乘法運(yùn)算.設(shè)計(jì)主要針對(duì)資源受限的應(yīng)用環(huán)境:改進(jìn)了有限域上的乘法運(yùn)算、使用了沒有預(yù)處理的標(biāo)量乘算法.改進(jìn)后的橢圓曲線標(biāo)量乘法需要2,741,998個(gè)邏輯單元,在100MHz的時(shí)鐘約束下,運(yùn)行一次標(biāo)量乘法運(yùn)算需要567.69us.該次設(shè)計(jì)的結(jié)果可以直接用來構(gòu)造橢圓曲線上的簽名、驗(yàn)證、密鑰交換等算法.

Abstract: A digital RF modulator, an integrated solution that satisfies stringent DOCSIS RF-performancerequirements, takes advantage of modern technologies like high-performance wideband digital-to-analogconversion and CMOS technology scaling. This application note describes the concept and advantages ofa digital quadrature amplitude modulation (QAM) modulator that uses the direct-RF architecture to enablea cable access platform (CCAP) system.

Abstract: Alexander Graham Bell patented twisted pair wires in 1881. We still use them today because they work so well. In addition we have the advantage ofincredible computer power within our world. Circuit simulators and filter design programs are available for little or no cost. We combine the twisted pair and lowpassfilters to produce spectacular rejection of radio frequency interference (RFI) and electromagnetic interference (EMI). We also illustrate use of a precision resistorarray to produce a customizable differential amplifier. The precision resistors set the gain and common mode rejection ratios, while we choose the frequencyresponse.

Abstract: A laser module designer can use a fixed resistor, mechanical pot, digital pot, or a digital-to-analogconverter (DAC) to control the laser driver's modulation and bias currents. The advantages of a programmablemethod (POT or DAC) are that the manufacturing process can be automated and digital control can be applied(e.g., to compensate for temperature). Using POTs can be a more simple approach than a DAC. There can be aslight cost advantage to using a POT, but this is usually not significant relative to other pieces of the design.Using a DAC can offer advantages, including improved linearity (translating to ease of software implementationand ability to hit the required accuracy), increased board density, a wider range of resolutions, a betteroptimization range, ease of use with a negative voltage laser driver, and unit-to-unit consistency

Control systems are becoming increasingly dependent on digital processing and so require sensors able to provide direct digital inputs. Sensors based on time measurement, having outputs based on a frequency or phase, have an advantage over conventional analogue sensors in that their outputs can be measured directly in digital systems by pulse counting.

Traditionally, an Electronic Circuit Breaker (ECB) comprisesa MOSFET, a MOSFET controller and a current senseresistor. The LTC®4213 does away with the sense resistorby using the RDS(ON) of the external MOSFET. The resultis a simple, small solution that offers a signifi cant lowinsertion loss advantage at low operating load voltage.The LTC4213 features two circuit breaking responses tovarying overload conditions with three selectable tripthresholds and a high side drive for an external N-channelMOSFET switch.
