CSR公司（倫敦證券交易所：CSR.L）日前推出SiRFstarIV GSD4e-9500 GPS引擎，這是首款SiRFstarIV架構(gòu)的GPS設(shè)備,，經(jīng)過優(yōu)化能夠滿足車載行業(yè)日趨嚴(yán)苛的需求。CSR公司此舉進(jìn)一步鞏固了自己在車載市場(chǎng)的領(lǐng)先地位,。該公司還宣布已經(jīng)開始發(fā)售車用級(jí)CSR8311，這是一款先進(jìn)的藍(lán)牙HCI設(shè)備,，首次將藍(lán)牙低功耗和寬帶語(yǔ)音（也稱高清語(yǔ)音）功能推廣到車載市場(chǎng),。
新的SiRFstarIV GSD4e-9500 GPS引擎與CSR8311藍(lán)牙和CSR6000 Wi-Fi連接設(shè)備一起，形成了一個(gè)完整的車用級(jí)定位與連接系統(tǒng),，為車載市場(chǎng)的一級(jí)供應(yīng)商和OEM廠商提供高性能的平臺(tái)解決方案,，在全球范圍內(nèi)為汽車和卡車實(shí)現(xiàn)各種車載導(dǎo)航和信息服務(wù)應(yīng)用。CSR公司日前還宣布推出適用于CSR6000的Wi-Linx軟件模塊,。（編者按：參見“用于CSR6000的CSR Wi-Linx 讓汽車成為滾燙的Wi-Fi熱點(diǎn)”,。）
CSR公司在Telematics Detroit 2011大會(huì)上展示了車用級(jí)硬件與軟件解決方案,，展會(huì)已于2011年6月8-9日在美國(guó)密歇根州諾維市舉行。
CSR公司車載與便攜式導(dǎo)航設(shè)備業(yè)務(wù)部高級(jí)副總裁Charlie Lesko表示：“GSD4e-9500的推出是我們同類最佳的車用級(jí)定位與連接組件組合不斷擴(kuò)展的一個(gè)重要里程碑,，表明了我們對(duì)車載市場(chǎng)的堅(jiān)定承諾,。有了GPS、藍(lán)牙和Wi-Fi解決方案這三駕馬車,，CSR公司未來(lái)幾年完全能夠滿足車載市場(chǎng)的定位和無(wú)線連接需求,。”
適用于汽車的SiRFstarIV：GSD4e-9500
新的GSD4e-9500首次為車載市場(chǎng)提供了全面突破的SiRFstarIV定位優(yōu)勢(shì)，包括主動(dòng)干擾移除技術(shù),，并且支持SiRFInstantFix客戶端和服務(wù)器生成的擴(kuò)展型星歷表以及SiRFDRive航跡推算技術(shù)。CSR公司獨(dú)有的主動(dòng)干擾移除技術(shù)能夠自動(dòng)預(yù)防汽車常見的帶內(nèi)電氣干擾,，使得GSD4e能夠提供卓越的GPS性能,。CSR公司的SiRFInstantFix擴(kuò)展型星歷表技術(shù)和SiRFDRive航跡推算技術(shù)能夠縮短首次定位時(shí)間，并提高定位精度——即使汽車內(nèi)部的天線布局不佳,，如位于儀表板下面也能提供精準(zhǔn)的定位,。
目前大多數(shù)汽車制造商對(duì)于藍(lán)牙和Wi-Fi的采用率和制造周期各不相同，這種模塊化的方法使得汽車客戶在制造車載信息娛樂和車信息服務(wù)系統(tǒng)時(shí)擁有了更大的靈活性,，能夠滿足特定的市場(chǎng)需求,。
CSR公司的汽車市場(chǎng)營(yíng)銷總監(jiān)Lars Boeryd表示：“GSD4e-9500給汽車市場(chǎng)提供了一款經(jīng)過市場(chǎng)驗(yàn)證的產(chǎn)品，它已經(jīng)在消費(fèi)市場(chǎng)和手機(jī)市場(chǎng)取得了高度的成功,，現(xiàn)在又首次作為AEC-Q100認(rèn)證設(shè)備上市,。推出GSD4e-9500后，CSR公司為一級(jí)汽車供應(yīng)商和OEM廠商更為廣泛地采用SiRFDRive敞開了大門,，并且現(xiàn)在能夠?yàn)槠囀袌?chǎng)提供各種完善的,、極具競(jìng)爭(zhēng)力的解決方案。”
除了能夠通過主動(dòng)干擾移除技術(shù)動(dòng)態(tài)偵測(cè),、跟蹤并主動(dòng)阻斷八種不同的干擾源外,，GSD4e-9500還具備一系列其它特點(diǎn)，如單SAW設(shè)計(jì),、片上LNA,、故障自動(dòng)保護(hù)型I/O、集成開關(guān),、單電源電壓,、簡(jiǎn)單RF匹配、以及小尺寸與封裝,，使設(shè)計(jì)者能夠更加輕松地采用它,，并把它整合在汽車平臺(tái)上，因此供應(yīng)商和OEM廠商在系統(tǒng)設(shè)計(jì)和天線布局方面擁有更大的靈活性,，并能夠縮短上市時(shí)間,。它還經(jīng)歷了更為嚴(yán)格AEC-100認(rèn)證流程以及制造,、組裝和測(cè)試程序，以滿足相對(duì)于消費(fèi)設(shè)備來(lái)說更高的車載品質(zhì)與可靠性標(biāo)準(zhǔn),。
適用于汽車的藍(lán)牙4.0：CSR8311
多家領(lǐng)先的汽車OEM廠商熱切期盼CSR8311能夠支持新出現(xiàn)的寬帶語(yǔ)音標(biāo)準(zhǔn),，而且這種支持對(duì)于車載免提通話的質(zhì)量和語(yǔ)音撥號(hào)功能的表現(xiàn)均有積極的影響，如今大多數(shù)的移動(dòng)電話一般都具備語(yǔ)音撥號(hào)功能,。
CSR8311為汽車制造商現(xiàn)有專用無(wú)鍵輸入技術(shù)提供了補(bǔ)充平臺(tái),，使駕駛?cè)藛T能夠通過其智能電話配置個(gè)性化的汽車設(shè)置，并使乘坐人員能夠遠(yuǎn)程控制車載娛樂系統(tǒng)及使用藍(lán)牙鍵盤訪問互聯(lián)網(wǎng),。這種技術(shù),，加上生物特征傳感器和某些汽車功能，還為各種各樣的車載保健應(yīng)用敞開了大門,，給具備某些醫(yī)療條件的駕駛?cè)藛T提供有用的信息,。
對(duì)于不斷發(fā)展的后坐娛樂市場(chǎng)來(lái)說，CSR8311能夠催生出各種各樣的立體聲耳機(jī)和遙控器,，并且還支持CSR aptX™無(wú)線高保真低延遲音頻壓縮技術(shù),，實(shí)現(xiàn)藍(lán)牙功能。CSR aptX技術(shù)采用先進(jìn)的ADPCM原理,，巧妙地將整個(gè)10Hz-22kHz高保真音頻頻率范圍壓縮到藍(lán)牙傳輸標(biāo)準(zhǔn)的有限帶寬范圍,，以提供高質(zhì)量的立體聲音頻還原功能，并具有極低延遲優(yōu)勢(shì),，避免了車載視頻娛樂系統(tǒng)的音唇不同步問題,。
適用于汽車的Wi-Fi熱點(diǎn)連接：用于 CSR6000的Wi-Linx
CSR公司日前還推出了適用于CSR6000的軟件模塊Wi-Linx，能夠?yàn)槿我馄囋黾覹i-Fi熱點(diǎn),、 Wi-Fi客戶端和藍(lán)牙3.0+HS功能,。CSR6000的Wi-Linx目前能夠用于Microsoft Windows CE 6.0和Microsoft Auto 4.1平臺(tái)，它增強(qiáng)了消費(fèi)者在下一代車載信息娛樂平臺(tái)上的無(wú)線體驗(yàn),，將Wi-Fi引入汽車以補(bǔ)充現(xiàn)有的藍(lán)牙功能,。
