根據(jù)市調(diào)機(jī)構(gòu)Linley Group表示，移動(dòng)系統(tǒng)的快速成長(zhǎng)正推動(dòng)業(yè)界邁向更優(yōu)質(zhì)的繪圖芯片、更佳語音質(zhì)量以及四核處理器。 優(yōu)質(zhì)的GPU 在移動(dòng)系統(tǒng)成為游戲平臺(tái)的首選之際，繪圖處理器(GPU)似乎也成了具關(guān)鍵性的投資領(lǐng)域。Linley Group首席分析師Linley Gwennap指出，“我認(rèn)為我們將看到智能手機(jī)上出現(xiàn)越來越多的游戲應(yīng)用，而在任天堂(Nintendo) 3D與索尼的Playstation Vita這一類專用設(shè)備上的游戲變得較少，甚至連平板電腦也可能分掉一部份原只為游戲機(jī)開發(fā)的游戲?！? 由于蘋果新款iPad整合較前一代型號(hào)更高兩倍的繪圖性能，Nvidia正試圖將游戲機(jī)上的多款游戲移植到該公司的 Tegra3芯片上。此外，高通公司(Qualcomm)最近也發(fā)布了專注于強(qiáng)化繪圖性能的Snapdragon S4 Pro處理器。 “移動(dòng)芯片的裸片照片顯示，GPU的硅晶用量正開始顯著增加?！?Gwennap說。 更佳語音質(zhì)量 移動(dòng)網(wǎng)絡(luò)和手機(jī)都已做好萬全準(zhǔn)備，通過支持更佳語音編碼器的方式，進(jìn)一步提升語音質(zhì)量。Gwennap表示，“我們看到了運(yùn)營(yíng)商開始實(shí)施一種可提供更高音質(zhì)的付費(fèi)服務(wù)模式。” Tensilica公司和高通公司已在其芯片設(shè)計(jì)中加進(jìn)這種功能了。他們還擴(kuò)展對(duì)于更廣泛音訊頻率范圍的支持，從傳統(tǒng)200Hz～3.6KHz的擴(kuò)展到未來的20Hz～20KHz范圍。 Gwennap認(rèn)為，相比在電腦上用SKYPE的用戶聽?wèi)T的高質(zhì)量語音，手機(jī)目前所提供的語音就如一堆噪音。 四核處理器 另一項(xiàng)重大的移動(dòng)產(chǎn)業(yè)發(fā)展趨勢(shì)是逐漸轉(zhuǎn)向采用四核架構(gòu)的處理器設(shè)計(jì)。Nvidia稍早前已經(jīng)推出Tegra 3超級(jí)芯片處理器，華為(Hwawei)在今年二月宣布一款類似的處理器芯片，而飛思卡爾(Freescale)也計(jì)劃在今年稍晚出貨其四核的處理器芯片。 “我認(rèn)為搭配采用適當(dāng)?shù)能浖r(shí)，顯然可讓四核處理器成為一款更好的解決方案，但大部分的Android應(yīng)用程序并未善加利用四核架構(gòu)的優(yōu)勢(shì)，而蘋果公司的iOS基礎(chǔ)架構(gòu)也未超越雙核心應(yīng)用?！彼f。 “當(dāng)今大部份的移動(dòng)軟件還用不到三核或四核，但隨著時(shí)間的推移，未來的一年將更有利于四核架構(gòu)的發(fā)展。” Gwennap補(bǔ)充道。 編譯：Susan Hong 本文授權(quán)編譯自EE Times，版權(quán)所有，謝絕轉(zhuǎn)載 參考原文：Analyst: Graphics war heating up in mobile，by Rick Merritt

{pagination} Analyst: Graphics war heating up in mobile SAN JOSE, Calif. – Mobile systems are driving toward better graphics, better voice quality and quad-core processors, according to veteran market watcher. Graphics seems to be key area of investment, as mobile systems become the game platform of choice,” said Linley Gwennap of the Linley Group (Mountain View, Calif.) “I think we will see more game play on smartphones and less on dedicated devices like the Nintendo 3DS and Sony Playstation Vita—even tablets are taking away from game consoles,” he said. Nvidia is trying to get console game titles ported to its Tegra3 chip as Apple courts developers to port games to the new iPad that packs twice the graphics capabilities of its previous model. Separately, Qualcomm recently launched its Snapdragon S4 Pro, mainly focused on enhanced graphics, he noted. “The amount of silicon devoted to the GPU is starting to increase significantly as we look at die photos of mobile chips, he said. Addressing the trend, Neil Trevett, head of the Khronos Group, will speak on mobile graphics in a keynote at an annual mobile conference Gwennap is hosting in San Jose in April. Separately, mobile networks and handsets are gearing up for increases in voice quality through support of improved audio codecs, Gwennap said. “We see a business model where carriers implement higher quality voice for a fee,” he said. Tensilica and Qualcomm are already offering such capabilities in silicon. Some of the work involves expanding support for broader audio frequency ranges from the traditional 200 Hz to 3.6 KHz of telephony to a range spanning 20 Hz to 20 KHz in the future, he said. “People using Skype on a PC already get those good voice experiences, but once you go back to a mobile phone it sounds like tin cans and a string,” he said. A slow move to quad core processors is the other major mobile trend in the works. Nvidia is there with its Tegra 3, Huawei announced a similar chip in February and Freescale is set to ship one later this year. “I think it’s clear with the right software quad core is a better solution [but] most Android apps don’t take advantage of quad cores, and Apple hasn’t pushed the iOS infrastructure for more than two cores yet,” he said. “Most of today’s mobile software is not really going to use three and four cores, but that will evolve over time and things will become more favorable for quad core over the year,” he added.
