關于FPGA流水線設計的論文 This work investigates the use of very deep pipelines for implementing circuits in FPGAs, where each pipeline stage is limited to a single FPGA logic element (LE). The architecture and VHDL design of a parameterized integer array MULTIPLIER is presented and also an IEEE 754 compliant 32-bit floating-point MULTIPLIER. We show how to write VHDL cells that implement such approach, and how the array MULTIPLIER architecture was adapted. Synthesis and simulation were performed for Altera Apex20KE devices, although the VHDL code should be portable to other devices. For this family, a 16 bit integer MULTIPLIER achieves a frequency of 266MHz, while the floating point unit reaches 235MHz, performing 235 MFLOPS in an FPGA. Additional cells are inserted to synchronize data, what imposes significant area penalties. This and other considerations to apply the technique in real designs are also addressed.

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? Software Development Environment 135-MHz Operation 48-Bit Data Path With 76-Bit Accumulator Hardware Single-Cycle MULTIPLIER (28 × 48)

無掃描激光雷達測距成像技術和其他測距系統相比具有可對動態物體清晰成像,功耗低,體積小,成本低廉的優點。無論在軍事上,還是在民用上都有非常重要的地位,是激光需達的重點研究方向。本論文介紹了四種基于不同原理的無掃描激光雷達方案。其中基于脈沖增益調制法的無掃描激光雷達具有很強的創造性,該方案使用脈沖光源,脈沖光源發出脈沖光照射目標物體,經物體反射后由功能光接收器MCP(Micro Channel Plate)接收,對MCP施加線性增益調制,在MCP輸出端形成新的光場,由CCD(Charge Couple Device)接收.CCD輸出的圖像經圖像處理后得到二維圖像信息。該方案對背景光干擾不敏感,可成像距離遠,具有很大的研究價值。本文設計了一套模擬系統來驗證基于脈沖調制法的無掃描激光雷達測距方案的可行性,由于光電倍增管PMr(Photoelectric electron-MULTIPLIER tube)在功能上和MCP具有最大的相似性,所以模擬系統中功能光接收器采用光電倍增管。系統由激光驅動模塊、PMT驅動模塊、時序控制模塊、采樣接收模塊四個部分組成。我們利用自行研制的模擬系統進行了大量的模擬實驗,經過對實驗結果分析發現該模擬系統的測量距離可達到1千米,測量誤差在15米以內,表明了該方案是確實可行的。論文最后對誤差來源進行了分析,并對整個項目進行了總結和展望。
