学术论文 ARMCoreSight跟踪调试技术的研究与应用
随着嵌入式系统的发展、嵌入式应用的不断增长以及嵌入式系统复杂性不断提高,嵌入式软件的规模和复杂性也不断提高。在目前的嵌入式系统开发中间,软件开发占80%以上的工作量,嵌入式软件的质量和开发周期对产品的最终质量和上市时间起到决定性的影响。因此,为了保持产品竞争力,支持用户对嵌入式设备进行快速、高效的软件 ...
学术论文 JPEG2000中小波变换的研究与FPGA实现
JPEG2000是新一代图像压缩标准,JPEG2000与传统JPEG最大的不同,在于它放弃了JPEG所采用的以离散余弦变换(Discrete Cosine Transform)为主的区块编码方式,而采用以小波转换(Wavelet Transform)为主的多解析编码方式.离散小波变换算法是现代谱分析工具,在图像处理与图像分析领域正得到越来越广泛的应用.由于JPEG2000标准具有复 ...
学术论文 基于FPGA的FFT数字处理器的硬件实现
DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具,直接计算DFT的计算量与变换区间长度N的平方成正比.当N较大时,因计算量太大,直接用DFT算法进行谱分析和喜好的实时处理是不切实际的.快速傅里叶变换(Fast Fourier Transformation,简称FFT)使DFT运算效率提高1~2个数量级.本 ...
学术论文 基于FPGA的图像处理算法及压缩编码
本文以“机车车辆轮对动态检测装置”为研究背景,以改进提升装置性能为目标,研究在Altera公司的FPGA(Field Programmable Gate Array)芯片Cyclone上实现图像采集控制、图像处理算法、JPEG(Joint Photographic Expert Group)压缩编码标准的基本系统。本文使用硬件描述语言Verilog,以RedLogic的RVDK开发板作为硬件平台,在开 ...
模拟电子 行为模式和同步事件调度操作
The Reactor design pattern handles service requests that are delivered concurrently to an application by one or more clients. Each service in an application may consist of serveral methods and is represented by a separate event handler that is responsible for dispatching service-specific requests. ...
电源技术 电信、数据通信和工业电源产品
In industrial applications, high voltage power supply spikes with durations ranging from a few microseconds to hundreds of millisecondsare commonly encountered. The electronics in these systems must not only survive transient voltage spikes, but in many cases alsooperate reliably throughout the ev ...
电源技术 电感开关稳压器提高输入电压
Abstract: Uses the MAX641 switching controller and an external discrete charge pump to step up the input voltage. This circuitcan service low loads and is efficient when the output is two, three, four times the input voltage. Adding the MAX627 MOSdriver can further increase the output current capa ...
电源技术 按键开关控制器简化系统设计
 
Handheld designers often grapple with ways to de-bounceand control the on/off pushbutton of portable devices.Traditional de-bounce designs use discrete logic, fl ipflops, resistors and capacitors. Other designs includean onboard microprocessor and discrete comparatorswhich continuously co ...
