  • XAPP520將符合2.5V和3.3V I/O標(biāo)準(zhǔn)的7系列FPGA高性能I/O Bank進(jìn)行連接

    XAPP520將符合2.5V和3.3V I/O標(biāo)準(zhǔn)的7系列FPGA高性能I/O Bank進(jìn)行連接  The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (HP) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas HP I/O banks are optimized for OPeration between 1.2V and 1.8V. In circumstances that require an HP 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series HP I/O banks with 2.5V and 3.3V systems

  • 嵌入式系統(tǒng)設(shè)計(jì)師教程

    嵌入式系統(tǒng)是一種應(yīng)用范圍非常廣泛的系統(tǒng)。可以說(shuō)除了桌面計(jì)算機(jī)和服務(wù)器外所有計(jì)算設(shè)備都屬于嵌入式系統(tǒng),例如從便攜式音樂(lè)播放器到航天飛機(jī)上的實(shí)時(shí)系統(tǒng)控制都屬于嵌入式系統(tǒng)。 大多數(shù)商用的嵌入式系統(tǒng)都設(shè)計(jì)成專用任務(wù)的低成本的產(chǎn)品。大多數(shù)的嵌入式系統(tǒng)都具有實(shí)時(shí)性的要求。有些功能需要非常快的主頻,但其他大多數(shù)功能并不需要高速的處理能力。這些系統(tǒng)通過(guò)特定的器件和軟件來(lái)滿足實(shí)時(shí)性的要求。 簡(jiǎn)單地通過(guò)速度和成本來(lái)定義嵌入式系統(tǒng)是困難的,但對(duì)于大批量的產(chǎn)品而言,成本常常對(duì)系統(tǒng)設(shè)計(jì)起決定作用。通常,一個(gè)嵌入式系統(tǒng)的很多部分相對(duì)系統(tǒng)主要功能來(lái)說(shuō)需要較低的性能,因此嵌入式系統(tǒng)和通用PC相比,能夠使用一個(gè)滿足輔助功能的合適的CPU,從而簡(jiǎn)化了系統(tǒng)設(shè)計(jì),降低了成本。例如,數(shù)字電視的機(jī)頂盒需要處理每秒以百萬(wàn)兆位計(jì)的連續(xù)數(shù)據(jù),但這些數(shù)據(jù)處理大部分是由定制的硬件來(lái)實(shí)現(xiàn)的,如解析、管理和編解碼多個(gè)頻道的數(shù)字影像。 對(duì)于大批量生產(chǎn)的嵌入式系統(tǒng),如便攜式音樂(lè)播放器或手機(jī)等,降低成本就成為最主要的問(wèn)題。這些系統(tǒng)通常只具有幾個(gè)芯片:一個(gè)高度集成的CPU,一個(gè)定制的芯片用于控制其他所有的功能,還有一個(gè)存儲(chǔ)芯片。在這種設(shè)計(jì)中,每部分都設(shè)計(jì)成使用最小的系統(tǒng)功耗。 對(duì)于小批量的嵌入式應(yīng)用,為了降低開(kāi)發(fā)成本,常常使用PC體系結(jié)構(gòu),通過(guò)限制程序的執(zhí)行時(shí)間或用一個(gè)實(shí)時(shí)操作系統(tǒng)來(lái)替換原先的操作系統(tǒng)。在這種情況下,可以使用一個(gè)或多個(gè)高性能的CPU來(lái)替換特殊用途的硬件。 嵌入式系統(tǒng)的軟件通常運(yùn)行在有限的硬件資源上:沒(méi)有硬盤(pán)、操作系統(tǒng)、鍵盤(pán)或屏幕。軟件一般都沒(méi)有文件系統(tǒng),如果有的話,也會(huì)采用Flash驅(qū)動(dòng)器。如果有人機(jī)交互接口的話,也是一個(gè)小鍵盤(pán)或液晶顯示器。硬件是計(jì)算機(jī)的物理部分,和存儲(chǔ)在硬件中的計(jì)算機(jī)軟件程序和數(shù)據(jù)區(qū)分開(kāi)來(lái)。 嵌入到機(jī)械中的嵌入式系統(tǒng)需要長(zhǎng)期無(wú)故障連續(xù)運(yùn)行,因此它的軟件需要比PC中的軟件更加仔細(xì)地開(kāi)發(fā)和更加嚴(yán)格地測(cè)試。 那么,到底什么是嵌入式系統(tǒng)呢? 根據(jù)IEEE(國(guó)際電氣和電子工程師協(xié)會(huì))的定義,嵌入式系統(tǒng)是“控制、監(jiān)視或者輔助設(shè)備、機(jī)器和車間運(yùn)行的裝置”(原文為devices used to control,monitor,or assist the OPeration of equipment,machinery or plants)。這主要是從應(yīng)用上加以定義的,從中可以看出嵌入式系統(tǒng)是軟件和硬件的綜合體,還可以涵蓋機(jī)械等附屬裝置。 目前國(guó)內(nèi)一個(gè)普遍被認(rèn)同的定義是:以應(yīng)用為中心、以計(jì)算機(jī)技術(shù)為基礎(chǔ),軟件     硬件可裁剪,適應(yīng)應(yīng)用系統(tǒng)對(duì)功能、可靠性、成本、體積、功耗嚴(yán)格要求的專用計(jì)算機(jī)系統(tǒng)。 可以這樣認(rèn)為,嵌入式系統(tǒng)是一種專用的計(jì)算機(jī)系統(tǒng),作為裝置或設(shè)備的一部分。通常,嵌入式系統(tǒng)是一個(gè)控制程序存儲(chǔ)在ROM中的嵌入式處理器控制板。事實(shí)上,所有帶有數(shù)字接口的設(shè)備,如手表、微波爐、錄像機(jī)、汽車等,都使用嵌入式系統(tǒng),有些嵌入式系統(tǒng)還包含操作系統(tǒng),但大多數(shù)嵌入式系統(tǒng)都是由單個(gè)程序?qū)崿F(xiàn)整個(gè)控制邏輯。 本書(shū)是按照人事部、信息產(chǎn)業(yè)部全國(guó)計(jì)算機(jī)技術(shù)與軟件專業(yè)技術(shù)資格(水平)考試要求編寫(xiě),內(nèi)容緊扣《嵌入式系統(tǒng)設(shè)計(jì)考試大鋼》。全書(shū)共六章,分別對(duì)嵌入式系統(tǒng)基礎(chǔ)知識(shí)、嵌入式微處理器與接口設(shè)計(jì)、嵌入式軟件與操作系統(tǒng)、嵌入式軟件程序設(shè)計(jì)、嵌入式系統(tǒng)設(shè)計(jì)與維護(hù)等知識(shí)進(jìn)行了詳細(xì)的講解。最后介紹了一個(gè)典型的嵌入式系統(tǒng)設(shè)計(jì)案例。 本書(shū)內(nèi)容豐富,結(jié)構(gòu)合理,概念清晰。既可作為全國(guó)計(jì)算機(jī)技術(shù)與軟件專業(yè)技術(shù)資格(水平)考試中嵌入式系統(tǒng)設(shè)計(jì)師級(jí)別的考試用書(shū),供有關(guān)考生學(xué)習(xí)使用,也可作為本科生嵌入式系統(tǒng)相關(guān)課程教材或培訓(xùn)書(shū)使用。

    The NCV7356 is a physical layer device for a single wire data linkcapable of operating with various Carrier Sense Multiple Accesswith Collision Resolution (CSMA/CR) protocols such as the BoschController Area Network (CAN) version 2.0. This serial data linknetwork is intended for use in applications where high data rate is notrequired and a lower data rate can achieve cost reductions in both thephysical media components and in the microprocessor and/ordedicated logic devices which use the network.The network shall be able to operate in either the normal data ratemode or a high-speed data download mode for assembly line andservice data transfer OPerations. The high-speed mode is onlyintended to be OPerational when the bus is attached to an off-boardservice node. This node shall provide temporary bus electrical loadswhich facilitate higher speed OPeration. Such temporary loads shouldbe removed when not performing download OPerations.The bit rate for normal communications is typically 33 kbit/s, forhigh-speed transmissions like described above a typical bit rate of83 kbit/s is recommended. The NCV7356 features undervoltagelockout, timeout for faulty blocked input signals, output blankingtime in case of bus ringing and a very low sleep mode current.

  • MAX7060的ASK_FSK的ISM射頻發(fā)射機(jī)

    Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved OPeration at 433.92MHz, a frequency commonly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.

  • 差分電路中單端及混合模式S-參數(shù)的使用

    Single-Ended and Differential S-Parameters Differential circuits have been important incommunication systems for many years. In the past,differential communication circuits operated at lowfrequencies, where they could be designed andanalyzed using lumped-element models andtechniques. With the frequency of OPerationincreasing beyond 1GHz, and above 1Gbps fordigital communications, this lumped-elementapproach is no longer valid, because the physicalsize of the circuit approaches the size of awavelength.Distributed models and analysis techniques are nowused instead of lumped-element techniques.Scattering parameters, or S-parameters, have beendeveloped for this purpose [1]. These S-parametersare defined for single-ended networks. S-parameterscan be used to describe differential networks, but astrict definition was not developed until Bockelmanand others addressed this issue [2]. Bockelman’swork also included a study on how to adapt single-ended S-parameters for use with differential circuits[2]. This adaptation, called “mixed-mode S-parameters,” addresses differential and common-mode OPeration, as well as the conversion betweenthe two modes of OPeration.This application note will explain the use of single-ended and mixed-mode S-parameters, and the basicconcepts of microwave measurement calibration.
