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 這是一個與記事本類似的簡單的SDI應用程序，演示了怎樣使用MFC來支持 Unicode，對指定的菜單條目進行Turkmenize標簽化。實際上，Windwos 2000并不支持Turknen,因此,創建了那些菜單資源以便那些字符串可以在Turknen中顯示,為此我必須開發其它的技術。 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.

信息技術的不斷發展,對信息的安全提出了更高的要求.在應用公鑰密碼體制的時候,對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數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)的快速實現也成為一個關注的方面.該文按照確定有限域、選取曲線參數、劃分結構模塊、優化模塊算法、實現模塊設計,驗證模塊功能的順序進行書寫.為了硬件實現上的方便,設計選擇了含有Ⅱ型優化正規基的伽略域GF(2191),并在該域上構造了隨機的橢圓曲線.根據層次化、結構化的設計思路,將橢圓曲線上的標量乘法運算劃分成兩個運算層次:橢圓曲線上的運算和有限域上的運算.模塊劃分之后,利用自底向上的設計思路,主要針對有限域上的乘法運算進行了重要的改進,并對加法群中的標量乘運算的算法進行了分析、證明,以達到面積優化和快速執行的效果.具體設計中,采用硬件描述語言Verilog HDL,在Mentor Graphics公司出品的FPGA advantage平臺上進行電路設計.完成了各個模塊的設計輸入和仿真.設計選用了Altera公司的APEX Ⅱ系列器件,利用第一方軟件Quartus Ⅱ 2.2進行綜合、布局、布線和時序仿真.文中給出了橢圓曲線上的點加、倍點和標量乘法模塊的具體設計結構框圖.并且根據橢圓曲線的標量乘特點,提出了合適的驗證方案.該設計完成了橢圓曲線上的標量乘法運算.設計主要針對資源受限的應用環境:改進了有限域上的乘法運算、使用了沒有預處理的標量乘算法.改進后的橢圓曲線標量乘法需要2,741,998個邏輯單元,在100MHz的時鐘約束下,運行一次標量乘法運算需要567.69us.該次設計的結果可以直接用來構造橢圓曲線上的簽名、驗證、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.
