Quake 3 s MD3 Viewer (july 13, 2007), loads and displays a player and a weapon. Supports lighting, texture mapping and animation. Includes a sample player model with weapon. See README for how to use it. Note (1): it uses the POSIX opendir/readdir functions, which are not implemented in all compilers under Windows (MinGW supports them). Note (2): This demo works on little endian architectures only. Libraries: OpenGL, GLU, GLUT, boost, libjpeg. Files: md3loader.zip (2.4 MB)

1 系統功能 本系統擬定對頻率范圍在1~50 kHz左右的TTL電平脈沖序列進行多路延遲處理。各路延遲時間分別由單片機動態設定，最大延遲時間為1 ms，最大分辨率為0.15 ns級。 3 方案實現 系統選用Actel公司的ProASIC3 A3P250芯片實現數字部分。系統時鐘由外部50 MHz晶振提供，時鐘引腳連接到FPGA的CCC全局時鐘引腳上；頻率可以通過FPGA內部的PLL實現倍頻和分頻，設定需要的頻率。由于在多路脈沖延遲方案中電路的同步是保證控制正確的條件，所以應該首先為電路提供一個基準脈沖。

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio? suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core. TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms. The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations. Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference. The TAS3204 is composed of eight functional blocks: Clocking System Digital Audio Interface Analog Audio Interface Power supply Clocks, digital PLL I2C control interface 8051 MCUcontroller Audio DSP – digital audio processing 特性 Digital Audio Processor Fully Programmable With the Graphical, Drag-and-Drop PurePath Studio?

Since the advent of optical communications, a great technological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Start- ing from a few Mb/s single channel systems, a fast and constant technological development has led to the actual 10 Gb/s per channel dense wavelength di- vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers.
