LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client. The client uses ncurses and is ideal for use with screen or dtach. It supports saving of sessions and allows the user to add and remove torrents.

The XC226x derivatives are high-performance members of the Infineon XC2000 Family of full-feature single-chip CMOS microcontrollers. These devices extend the functionality and performance of the C166 Family in terms of instructions (MAC unit), peripherals, and speed. They combine high CPU performance (up to 80 million instructions per second) with extended peripheral functionality and enhanced IO capabilities. Optimized peripherals can be adapted flexibly to meet the application requirements. These derivatives utilize clock generation via PLL and internal or external clock sources. Onchip memory modules include program Flash, program RAM, and data RAM.

High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.

數字控制的交流調速系統所選用的微處理器、功率器件及產生PWM波的方法是影響交流調速系統性能好壞的直接因素。在介紹了正弦脈寬調制(SPWM)技術的基礎上,設計了一種以8098單片機作為控制器,以智能功率模塊IPM為開關器件的變頻調速系統。通過軟件編程,產生正弦脈沖寬度調制波形來控制絕緣柵雙極晶體管的導通和關斷,從而達到控制異步電動機轉速的目的。實驗結果表明,該系統可調頻率調電壓,穩定度高,調速范圍寬,具有較強的實用價值 Abstract: AC variable speed with digital control systems used microprocessors, power devices and generate PWM wave is the direct factors of affecting the performance AC speed regulation system. On the basis of introducing the sinusoidal pulse width modulation (SPWM) technology,this paper designed variable speed system which used 8098 as a controller, intelligent power module IPM as switching device. Through software programming, resulting in sinusoidal pulse width modulation waveform to control the insulated gate bipolar transistor turn on and off, so as to achieve the purpose of speed control of induction motors. Experimental results show that the system can adjust frequency modulation voltage, high stability, wide speed range, has a strong practical value.
