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.

VHDL是由美國國防部為描述電子電路所開發(fā)的一種語言，其全稱為(Very High Speed Integrated Circuit) Hardware Description Language。 與另外一門硬件描述語言Verilog HDL相比，VHDL更善于描述高層的一些設(shè)計，包括系統(tǒng)級（算法、數(shù)據(jù)通路、控制）和行為級（寄存器傳輸級），而且VHDL具有設(shè)計重用、大型設(shè)計能力、可讀性強、易于編譯等優(yōu)點逐漸受到硬件設(shè)計者的青睞。但是，VHDL是一門語法相當(dāng)嚴(yán)格的語言，易學(xué)性差，特別是對于剛開始接觸VHDL的設(shè)計者而言，經(jīng)常會因某些小細(xì)節(jié)處理不當(dāng)導(dǎo)致綜合無法通過。為此本文就其中一些比較典型的問題展開探討，希望對初學(xué)者有所幫助，提高學(xué)習(xí)進(jìn)度。

For nearly a hundred years telecommunications provided mainly voice services and very low speed data (telegraph and telex). With the advent of the Internet, several data services became mainstream in telecommunications; to the point that voice is becoming an accessory to IP-centric data networks. Today, high-speed data services are already part of our daily lives at work and at home (web surfing, e-mail, virtual private networks, VoIP, virtual meetings, chats...). The demand for high-speed data services will grow even more with the increasing number of people telecommuting.

Wireless metropolitan area networks (WirelessMANs) is emerging as a promising broadband wireless access (BWA) technology to provide high-speed, high bandwidth efficiency and high-capacity multimedia services for residential as well as enterprise applications. It is observed that WirelessMAN (e.g., WiMAX) is even regarded as a 4G technology. For the success of the WirelessMANs, international standardization organiza- tions are very actively specifying the standards IEEE 802.16, ETSI HiperMAN and Korea WiBro.
