恩智浦半導(dǎo)體（nxp semiconductors，由飛利浦創(chuàng)建的獨(dú)立半導(dǎo)體公司）與臺(tái)灣積體電路制造股份有限公司（臺(tái)積電）9日宣布，雙方合作推出業(yè)界第一個(gè)符合全球規(guī)格的45納米單晶片液晶電視平臺(tái)——tv550。目前恩智浦半導(dǎo)體已經(jīng)將工程樣品（engineering samples）交予其主要客戶。 恩智浦半導(dǎo)體的 tv550 數(shù)字電視平臺(tái)，內(nèi)建pnx85500 處理器，并采用臺(tái)積電45納米低耗電制程技術(shù)生產(chǎn)，目前已經(jīng)是一項(xiàng)生產(chǎn)就緒(production-ready)的設(shè)計(jì)，不但可以加速數(shù)字電視系統(tǒng)產(chǎn)品的上市時(shí)間，并能經(jīng)由其完整的功能整合來降低系統(tǒng)成本。此一嶄新的數(shù)字電視平臺(tái)能讓電視觀眾以前所未有的畫面品質(zhì)享受高畫質(zhì)數(shù)字內(nèi)容及網(wǎng)絡(luò)服務(wù)。恩智浦半導(dǎo)體與臺(tái)積電的長(zhǎng)期伙伴關(guān)系與合作是此一平臺(tái)能順利問世的關(guān)鍵，藉由先進(jìn)的psp電晶體模擬軟體，臺(tái)積電能夠及早提供晶片測(cè)試結(jié)果，并獲得準(zhǔn)確的電晶體模擬效能。 由于臺(tái)積電于2007年領(lǐng)先推出45納米制程技術(shù)，恩智浦半導(dǎo)體主動(dòng)與臺(tái)積電合作，使得此一數(shù)字電視平臺(tái)能在最快時(shí)間內(nèi)上市。恩智浦半導(dǎo)體選擇臺(tái)積電45納米低耗電制程，是著眼于許多優(yōu)異的功能表現(xiàn)，譬如具
