This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory is controlled by a controller that attaches to either the OPB or PLB and is used inan EMbedded microprocessor application. This reference system also uses a DCM that isconfigured so that the phase of its output clock can be changed while the system is running anda GPIO core that controls that phase shift. The GPIO output is controlled by a softwareapplication that can be run on a PowerPC® 405 or Microblaze™ microprocessor.

The introduction of Spartan-3™ devices has createdmultiple changes in the evolution of EMbedded controldesigns and pushed processing capabilities to the “almostfreestage.” With these new FPGAs falling under $20, involume, with over 1 million system gates, and under $5for 100K gate-level units, any design with programmablelogic has a readily available 8- or 16-bit processor costingless than 75 cents and 32-bit processor for less than $1.50.

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.

針對(duì)嵌入式機(jī)器視覺(jué)系統(tǒng)向獨(dú)立化、智能化發(fā)展的要求，介紹了一種嵌入式視覺(jué)系統(tǒng)--智能相機(jī)。基于對(duì)智能相機(jī)體系結(jié)構(gòu)、組成模塊和圖像采集、傳輸和處理技術(shù)的分析，對(duì)國(guó)內(nèi)外的幾款智能相機(jī)進(jìn)行比較。綜合技術(shù)發(fā)展現(xiàn)狀，提出基于FPGA+DSP模式的硬件平臺(tái)，并提出智能相機(jī)的發(fā)展方向。分析結(jié)果表明，該系統(tǒng)設(shè)計(jì)可以實(shí)現(xiàn)脫離PC運(yùn)行，完成圖像獲取與分析，并作出相應(yīng)輸出。 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.

SL811開(kāi)發(fā)資料_包含源程序_電路圖_芯片資料:SL811HS EMbedded USB Host/Slave Controller.The SL811HS is an EMbedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

We intend to develop a wifi enabled p2p file sharing system on a linux platform using jxta and java. The purpose is to build a system that can be ported to an EMbedded device at a later stage and be used for p2p file sharing using the 802.11b standard. 我們旨在Linux平臺(tái)上使用jxta 和java來(lái)開(kāi)發(fā)一個(gè)支持wifi的p2p文件共享系統(tǒng)。其目的是建造一個(gè)以后可以移植到嵌入式設(shè)備的系統(tǒng)，使用802.11b標(biāo)準(zhǔn)進(jìn)行p2p文件共享。 來(lái)源: http://sourceforge.net/projects/linux-p2p-wifi/

JILRuntime A general purpose, register based virtual machine (VM) that supports object-oriented features, reference counting (auto destruction of data as soon as it is no longer used, no garbage collection), exceptions (handled in C/C++ or virtual machine code) and other debugging features. Objects and functions can be written in virtual machine code, as well as in C or C++, or any other language that can interface to C object code. The VM is written for maximum performance and thus is probably not suitable for EMbedded systems where a small memory footprint is required. Possible uses of the VM are in game development, scientific research, or to provide a stand-alone, general purpose programming environment.
