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。
& n1 x: K1 e5 v$ f. I7 `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。
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。
6 g3 \5 R7 u! _+ i% s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 o1 s5 J; e  K# Z8 J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。
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。
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。

BROADCOM UNVEILS NETBOOK VIDEO DECODER
The Crystal HD video decoder boosts performance on netbooks using Intel's latest N450 Atom processor.
By Antone Gonsalves , 2009/12/23

# y2 `5 r/ G+ P9 v9 [Broadcom has introduced a single-chip video decoder for computer manufacturers that want to give a performance boost to Intel's latest Atom platform for netbooks.
! I( m  u/ d7 GThe Crystal HD is being offered for netbooks that use Intel's new N450 Atom processor and NM10 Express chipset. Broadcom says Asus, Dell, Samsung, and other manufacturers will ship netbooks with Crystal HD next year.
The new product is based on Broadcom's BCM70015 single-chip, high-definition video decoder. The company claims its product is "low-cost, low-power" technology that can deliver quality playback of streaming HD video.
$ D, c+ S: f) v* Y# l, J/ W/ BNetbooks, which are inexpensive mini-laptops with screens between seven and 10 inches, are built for basic computing tasks, such as Web browsing and e-mail. Broadcom and other companies offer chips that offload video and graphics from the CPU in order to boost system performance.
- {" M7 g* C4 s& D% R  p: ^"Our Crystal HD technology provides high-quality video playback within a low-power, low-cost solution that will enhance the consumer netbook experience in 2010," said Dan Eiref, VP and general manager of Broadcom's consumer electronics division.
Crystal HD uses similar technology to that Broadcom makes for set-top boxes and consumer media players. The netbook product can play back video in multiple formats, such as H.264/AVC, MPEG-2, VC-1, WMV9, MPEG-4, DivX, Xvid, and AVS. The technology also supports popular media players, including Windows Media Player and Adobe Flash Player.
Intel introduced its next-generation Atom platform on Monday. A major advancement in the latest netbook platform from the previous generation is the integration of a graphics and memory controller on the same piece of silicon as the CPU. The combo reduces the number of chips from three in previous products to two, which will make it possible for computer makers to build slimmer netbooks, according to Intel.
