博通(Broadcom)公司發表其新世代多媒體處理器BCM2763 VideoCore IV,具備更高效能與更低功耗,採用40奈米(40nm) CMOS製程技術,能夠比65奈米產品的整合性更高,且佔用的空間更小、功耗更低。 # |0 u7 h, v1 u- \2 g
藉由40奈米COMS製程技術提供的更高整合度及大幅節能等特性,BCM2763多媒體處理器能支援最先進的行動高畫質(HD)攝影機及影像播放裝置、高達2千萬畫素的數位相機和照片處理功能,以及高解析度的1gigapixel 2D/3D繪圖能力,為消費者提供世界級的遊戲體驗。 1 Z Z, r* C' b2 N0 x, \
利用該晶片內建的標準HDMI介面,還可以在全尺寸的高畫質電視播放最高品質的高畫質影像、3D遊戲和高解析度達2千萬畫素的影像。此外,由於BCM2763的高整合性架構能降低物料成本,使得更多低價手機得以嵌入尖端先進的多媒體功能。 ' u2 R2 C. s% C" u% [4 E& z
最新的Broadcom BCM2763 VideoCore IV多媒體處理器可讓手機具備Full HD 1080p的攝影機功能,大幅超越目前一般手機的影像品質(通常只具備VGA或更低解析度的攝影功能)。其高達2千萬畫素的數位相機具備多種先進功能,如每秒連拍數張照片、相機防手震、臉部表情及笑容偵測以及全景拍攝模式。 % |2 k# }* m6 z& Y$ X
此外,還有高達1080p解析度的行動遊戲影像畫質,並內建HDMI輸出功能,可在大型螢幕的高畫質電視提供遊戲機品質的遊戲體驗。除了讓新手機具備這些功能外,藉由40奈米製程技術大幅提升的節能效率,使BCM2763既不會大量消耗電池電力,也不至於大幅縮短手機通話時間。 8 ?5 D5 D8 X7 A% z3 F1 U$ J
在低功耗性能方面,新款多媒體處理器據稱較前一代Videocore III多媒體處理器功耗減少20%∼50%。只要手機的儲存容量夠,即可錄影4到6小時的1080p畫質影片、播放8到10小時的行動影片,並透過HDMI介面播放16小時的Full HD影片。1080p攝影機H.264 High Profile編碼的晶片功率只需490mW,播放1080p畫面的晶片功率只需160mW。行動遊戲的繪圖處理只需160mW功率,每秒填充率高達1gigapixel,且繪圖效能是Videocore III多媒體處理器的4到6倍。 ! f7 T2 m2 v) I, q/ n
BCM2763將8種晶片的功能整合在一起,以單一封裝堆疊GPU及圖形記憶體、影像訊號處理(ISP)及ISP記憶體、視訊處理及視訊記憶體、HDMI及USB 2.0. 128MB的LPDDR2圖形記憶體。40奈米製程可降低功率、提升效能並減少手機機板的空間。 % H3 }% G" Y, _& L( w4 I
