如果你關(guān)注2007年的電腦資訊，哪么2007年電腦出現(xiàn)頻率最高的宣傳術(shù)語(yǔ)可能是： 某某電腦的CPU采用雙核、64位處理器！ 而在此之前，我們的家用PC主要采用32位的CPU，本節(jié)課程將討論單片機(jī)CPU的位數(shù) CPU的位數(shù)也稱(chēng)為位寬，是指CPU一次執(zhí)行指令的數(shù)據(jù)帶寬。例如4位CPU一次只能處理4位二進(jìn)制數(shù)，單片機(jī)的發(fā)展經(jīng)歷過(guò)4位、8位、16位，現(xiàn)在已經(jīng)有32位的單片機(jī)，而家用PC的CPU以達(dá)到主流的64位。 自從1974年美國(guó)Fairchild公司研制出第一臺(tái)單片機(jī)F8之后，迄今為止，單片機(jī)經(jīng)歷了由4位機(jī)到8位機(jī)再到16位機(jī)的發(fā)展過(guò)程。單片機(jī)制造商很多，主要有美國(guó)的Intel、Motorola、Zilog等公司。目前，單片機(jī)正朝著高性能、多品種方向發(fā)展。近年來(lái)，32位單片機(jī)已進(jìn)入了實(shí)用階段，但是由于8位單片機(jī)在性能價(jià)格比上占有優(yōu)勢(shì)，而且8位增強(qiáng)型單片機(jī)在速度和功能上向現(xiàn)在的16位單片機(jī)挑戰(zhàn)，因此在未來(lái)相當(dāng)長(zhǎng)的時(shí)期內(nèi)，8位單片機(jī)仍是單片機(jī)的主流機(jī)型。 八位單片機(jī)是目前品種最為豐富、應(yīng)用最為廣泛的單片機(jī)，有著體積小、功耗低、功能強(qiáng)、性能價(jià)格比高、易于推廣應(yīng)用等顯著優(yōu)點(diǎn)。目前主要分為MCS-51系列及其兼容機(jī)型和非MCS-51系列單片機(jī)。   MCS-51兼容產(chǎn)品因開(kāi)發(fā)工具及軟硬件資源齊全而占主導(dǎo)地位， ATMEL、PHILIPS、WINBOND是MCS-51單片機(jī)生產(chǎn)的老牌廠家，CYGNAL及ST也推出新的產(chǎn)品，其中ST的新推出的μPSD系列片內(nèi)有大容量FLASH（128/256KB）、8/32KB的SRAM、 集成A/D、看門(mén)狗、上電復(fù)位電路、兩路UART、支持在系統(tǒng)編程ISP及在應(yīng)用中編程IAP等諸多先進(jìn)特性，迅速被廣大51單片機(jī)用戶(hù)接受。   非51系列單片機(jī)在中國(guó)應(yīng)用較廣的有MOTOROLA68HC05/08系列、 MICROCHIP的PIC單片機(jī)以及ATMEL的

May 21, 2012 - Acromag acquired the assets of Xembedded. This purchase adds the products of Xembedded to Acromag’s portfolio, benefitting both groups by combining product lines. Customers will have the advantage of a complete product solution, ranging from CPU products to I/O solutions. “Xembedded products are known for high quality and technology. Their focus on VME, VPX, and COM Express platforms complements Acromag’s FPGA, PMC, XMC, and I/O technologies,” stated David Wolfe, President of Acromag. This move also extends production of the many legacy products that Xembedded, LLC is known for. The new “Xembedded Group” will now join the Acromag “Embedded Solutions Group” and “Process Instrument Group.” By forming this new group, Acromag is able to provide uninterrupted service to former Xembedded customers. Along with the products, Acromag has hired all of the employees of Xembedded in order to maintain the expertise to design, manufacture, and support the many products in the “Xembedded Group” portfolio. The new Xembedded Group will also work to continue relationships with the many sales representatives and distributors that have sold Xembedded products for years. Xembedded has developed embedded solutions for over three decades. Their processor and I/O VME boards are used in machine control, medical equipment, automotive, robots, scanning equipment, semi-conductor manufacturing, homeland security, military, industrial welders, power generation, and high-speed packaging applications.
