2GHz ARMプロセッサはLinuxデバイスの為に

ARMのコアデザイナが水曜に発表した2GHzのCortex-A9マイクロプロセッサは,
特にスマートフォンやスマートブック(ref:wikipedia)向けであるようだ.

Embedded core designer ARM Ltd. on Wednesday announced a 2-GHz version of its Cortex-A9 microprocessor that may eventually appear in smartphones and smartbooks.

ARMは第四四半期にこのIPコア(ref:wikipedia)を出荷する.
つまりこのテクノロジを搭載した製品は来年以降になりそうだ.

ARM will deliver the core IP itself during the fourth quarter, so any products based on the technology will likely have to wait until the new year.

ARMはCortex-A9のマルチコアをIntel Atomとの対抗馬にしたいところだが,
Microsoftが6月に発表したことによれば,Windows 7はARMアーキテクチャ上では動作しない.
つまり,FreeScaleのような会社がLinuxベースのスマートブックにこのIPコアを使用するということだ.
しかし2月以降,スマートブックのコンセプトは不明のままだ.

Although ARM would like the Cortex-A9 MPcore to compete against the Intel Atom, Microsoft said in June that Windows 7 would not run on the ARM architecture. That would mean that companies like FreeScale would have to use the core in Linux-powered "smartbooks,", which the company later enhanced. Since February, however, the smartbook concept has gone quiet.

しかしARMはスマートブックがターゲットであると明言していない.
掃除にこのIPコアのピーク電流が半分であることを示唆し,
スマートフォン市場にも向いていることがわかる.

ARM didn't specifically identify smartbooks as a target market, however, and indicated that the cores combined would consume just half a watt while running at peak output, which would make the core probably more tailored to the smartphone market.

技術面では,この2コアは8MBの共有キャッシュを持つ.
ARMはこのCortex-A9マルチコアに最適な製造プロセスがどれかを公表していない.
またAtomやほかのマイクロプロセッサと対抗する価格も公表していない.

From a technology perspective, the two cores will share 8 Mbytes of cache. The company did not reveal what process technology the Cortex-A9 MPCore would be optimized for, nor how clients would price it versus the Atom or other embedded microarchitectures.

謎多き時期ARM...
