title="應用處理器">應用處理器。這兩款處理器獲得了汽車電子委員會(AEC)Q-100認證，為汽車原始設備制造商（OEM）提供一種強大的解決方案，以實現駕駛員所需的下列特性：免提電話操作、語音識別以及語音和媒體的高速數據傳輸、GPS 導航和AV娛樂等特性。這些處理器促進了消費電子器件，如手機、便攜式媒體播放器與汽車環境的無縫連接。
??? 2007年早些時候，福特和微軟宣布推出SYNC車載通信和娛樂系統，并應用于帶有SYNC系統的福特2008款車內。這是首款基于i.MX31處理器的汽車應用。福特SYNC是基于微軟汽車平臺的一個完全集成的、可更新的與可定制的媒體系統。該系統允許汽車乘坐者操作支持藍牙的移動電話和幾乎所有的便攜式媒體播放器，這些設備在方向盤上帶有簡單的語音命令或手動控制，SYNC可以讓用戶在車輛中控制并個性化他們的電子設備。飛思卡爾的i.MX31處理器是SYNC不可或缺的一部分，它運行微軟操作系統和應用程序、處理免提操作的音頻信號，并實現語音識別。此外，i.MX31芯片利用USB技術實現SYNC系統與手機或便攜式媒體設備之間的高速數據傳輸。
杰出的i.MX31處理器
??? i.MX31處理器基于ARM11TM平臺，在運行高性能的車載通信和信息娛樂系統的同時，提供400MHz處理速度和高效的存儲系統，如L-2高速緩存。由于符合AEC標準的嚴格規范，汽車級i.MX31處理器可以向飛思卡爾客戶確保在苛求的汽車環境中提供統一標準和可靠性。
??? i.MX31處理器配備專用的多媒體加速器，使ARM11內核的處理能力用于面向消費者的軟件、導航和其他任務中。一個例子就是飛思卡爾專用的圖像處理單元可執行后視鏡與取景器任務，無需中央處理器干涉。i.MX31處理器以非常低的功率運行，最大程度地降低儀表板中的熱量聚積。如圖1所示。
?
??? iSuppli汽車電子公司首席分析師Richard Robinson表示：“隨著飛思卡爾汽車級i.MX31應用處理器的推出，它為當今汽車駕駛員帶來了新水平的通信和娛樂功能。憑借其卓越的技術專業知識和創新，飛思卡爾半導體多年來一直是汽車行業的未來解決方案提供商。非常高興看到汽車廠商在動態的汽車信息娛樂領域不斷發展壯大。”
??? 飛思卡爾i.MX31應用處理器為客戶利用不同的軟件提供強大的中央處理單元(CPU)。由于其高效的存儲架構和向量浮點單元，它還可提供卓越的語音識別性能。
??? i.MX31汽車級處理器支持多個操作系統和應用框架，支持市場和汽車OEM的不同要求。支持的操作系統包括Microsoft? Auto、Linux? OS、QNX? Neutrino?以及其他領先的RTOS。
??? QNX軟件系統公司營銷副總裁Dave Curley表示：“我們高度重視與飛思卡爾的關系，而且非常高興能與他們一起來增強汽車市場的滲透。隨著車載通信和娛樂系統的演進，飛思卡爾技術與QNX軟件的整合能使消費者最大程度提高其多媒體設備的功能，實現高效、令人愉快的駕駛體驗。”
針對汽車應用的i.MX31增強功能
??? 作為全球領先的半導體公司，飛思卡爾半導體不斷推出i.MX系列應用處理器。基于ARM核心技術的i.MX系列產品，擁有超過10年的技術經驗，并被廣泛地應用于智能電話、無線PDA、移動娛樂和多種其他移動無線產品。其設計宗旨是實現低功耗、高性能，大幅度縮短設計時間。融合了先進的低功耗技術，并且針對汽車行業進行了增強的i.MX31處理器，能夠符合汽車OEM的嚴格質量和可靠性標準。例如，汽車級i.MX31設備具有速度高達400 MHz的CPU，并且能夠在-40°C～+85°C的溫度范圍中運行。處理器封裝為473MAPBGA、0.8mm間距，符合RoHS標準。關于i.MX系列和Smart SpeedTM技術
??? 飛思卡爾的i.MX系列應用處理器主要用于智能電話、便攜式媒體播放器、便攜式導航設備、視頻監控、銷售點終端系統、條形碼掃描器及許多其他通用嵌入式應用。i.MX系列基于ARM? 核心技術，采用Smart Speed技術設計制造，以最低的功耗提供高功率性能。廣泛的集成有助于大大減少設計時間。飛思卡爾為設計工程師提供各種i.MX處理器選擇，如：面向價格敏感應用的i.MXS、面向中端設備的i.MXL和i.MX21S以及面向高性能場合的i.MX21、i.MX27 和i.MX31處理器。i.MX系列支持多種平臺，包括基于Microsoft Windows、Linux操作系統以及大量領先的實時操作系統的平臺。i.MX處理器封裝符合RoHS標準。
??? i.MX31處理器系列利用飛思卡爾的Smart Speed技術架構，使設計者可以在較少的eCPI（有效單位指令循環）及功耗下實現平行處理。它通過6×5 Smart Speed的交叉開關，實現系統并行處理，幾乎消除了停滯狀態，使處理器的性能與時鐘速度高達3GHz的處理器相同，但又不會因高運行頻率而導致高功耗。
??? i.MX31汽車級處理器目前可以批量銷售，您可以通過經銷商或者直接從飛思卡爾訂購。支持的操作系統包括Microsoft? Windows? CE、Linux? OS、QNX? Neutrino? 以及其他著名的RTOS。i.MX31LC版本每萬件的建議零售價為21.80美元，帶有片上3D圖形加速器的i.MX31C處理器版本每萬件的建議零售價為24.86美元。如需了解飛思卡爾i.MX應用處理器系列的更多信息，請訪問： www.freescale.com/imx.
