The Xilinx Zynq-7000 Extensible Processing Platform (EPP) redefines the possibilities for embedded systems, giving system and software architects and developers a flexible platform to launch their new solutions and traditional ASIC and ASSP users an alternative that aligns with today’s programmable imperative. The new class of product elegantly combines an industrystandard ARMprocessor-based system with Xilinx 28nm programmable logic—in a single device. The processor boots first, prior to configuration of the programmable logic. This, along with a streamlined workflow, saves time and effort and lets software developers and hardware designers start development simultaneously.

针对嵌入式机器视觉系统向独立化、智能化发展的要求,介绍了一种嵌入式视觉系统--智能相机。基于对智能相机体系结构、组成模块和图像采集、传输和处理技术的分析,对国内外的几款智能相机进行比较。综合技术发展现状,提出基于FPGA+DSP模式的硬件平台,并提出智能相机的发展方向。分析结果表明,该系统设计可以实现脱离PC运行,完成图像获取与分析,并作出相应输出。 Abstract: This paper introduced an embedded vision system-intelligent camera ,which was for embedded machine vision systems to an independent and intelligent development requirements. Intelligent camera architecture, component modules and image acquisition, transmission and processing technology were analyzed. After comparing integrated technology development of several intelligent cameras at home and abroad, the paper proposed the hardware platform based on FPGA+DSP models and made clear direction of development of intelligent cameras. On the analysis of the design, the results indicate that the system can run from the PC independently to complete the image acquisition and analysis and give a corresponding output.

波长信号的解调是实现光纤光栅传感网络的关键,基于现有的光纤光栅传感器解调方法,提出一种基于FPGA的双匹配光纤光栅解调方法,此系统是一种高速率、高精度、低成本的解调系统,并且通过引入双匹配光栅有效地克服了双值问题同时扩大了检测范围。分析了光纤光栅的测温原理并给出了该方案软硬件设计,综合考虑系统的解调精度和FPGA的处理速度给出了基于拉格朗日的曲线拟合算法。 Abstract: Sensor is one of the most important application of the fiber grating. Wavelength signal demodulating is the key techniques to carry out fiber grating sensing network, based on several existing methods of fiber grating sensor demodulation inadequate, a two-match fiber grating demodulation method was presented. This system is a high-speed, high precision, low-cost demodulation system. And by introducing a two-match grating effectively overcomes the problem of double value while expands the scope of testing. This paper analyzes the principle of fiber Bragg grating temperature and gives the software and hardware design of the program. Considering the system of demodulation accuracy and processing speed of FPGA,this paper gives the curve fitting algorithm based on Lagrange.

ORCAD在使用的时候总会出现这样或那样的问题…但下这个问题比较奇怪…在ORCAD中无法输出网表…弹出下面的错误….这种问题很是奇怪…Netlist Format: tango.dllDesign Name: D:\EDA_PROJECT\PROTEL99SE\YK\SV3200\MAIN.DSNERROR [NET0021] Cannot get part.[FMT0024] Ref-des not found. Possible Logical/Physical annotation conflict.[FMT0018] Errors processing intermediate file找了一天没找到问题…终于在花了N多时间后发现问题所在…其实这个问题就是不要使用ORCAD PSPICE 库里面的元件来画电路图…实际中我是用了PSPICE里面和自己制作的二种电阻和电容混合在一起…就会出现这种问题…

The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。 Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.

The data plane of the reference design consists of a configurable multi-channel XBERT modulethat generates and checks high-speed serial data transmitted and received by the MGTs. Eachchannel in the XBERT module consists of two MGTs (MGTA and MGTB), which physicallyoccupy one MGT tile in the Virtex-4 FPGA. Each MGT has its own pattern checker, but bothMGTs in a channel share the same pattern generator. Each channel can load a differentpattern. The MGT serial rate depends on the reference clock frequency and the internal PMAdivider settings. The reference design can be scaled anywhere from one channel (two MGTs)to twelve channels (twenty-four MGTs).

There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of LCD controller devices is determined by signals sent from a central processing unit(in this case, a CoolRunner-II CPLD).
