iFixit:A6的ARM核心竟然是手工Layout - 工程師

According to iFixIt:

When compared to the rigid, efficient layout of the GPU cores directly below
it, the layout of the ARM cores looks a little homespun—at first.

- Generally, logic blocks are automagically laid out with the use of advanced
computer software. However, it looks like the ARM core blocks were laid out
manually—as in, by hand.

- A manual layout will usually result in faster processing speeds, but it is
much more expensive and time consuming.

- The manual layout of the ARM processors lends much credence to the rumor
that Apple designed a custom processor of the same caliber as the all-new
Cortex-A15, and it just might be the only manual layout in a chip to hit the
market in several years.

雖然我對Intrinsity真的採取Full Costum保持懷疑,Manual Layout這個說法也太籠統。

不過感覺得出來阿婆已經開始朝用 ARM 架構授權而自行開發處理器的路發展。現在在A6

這個看到高度客製化的成果,又看到IP5一無可取得超爛發表會,難道阿婆開始要走硬體

路線嗎?

Steve Jobs事業一值以來都想搞好硬體...但是都是軟體部分
Dinah avatarDinah2012-09-29
跟硬體合體才有以後的發展...看看那精美的Next工作站.....

做cpu的custom design custom layout有啥好奇怪的
Susan avatarSusan2012-10-06
阿婆這樣做就很怪,重點是沒必要自己來。不像AMD需要這

麼辛苦的去賺那少少的$$$

Apple 是拿來獨佔市場..跟AMD 拿出去賣的不同..
Quintina avatarQuintina2012-10-16
未來就算拿其他CPU 也沒辦法跑iOS系統..

全部CUSTOM不可能吧 應該有一些macro是

setup/hold time自己猜?

PA-semi裡面的都是一些老牌cpu咖 當然知道怎麼搞最好
Damian avatarDamian2012-10-23
apple扶持自家原pa-semi團隊的人目的也很清楚阿
Eden avatarEden2012-10-28
就是以後逐步擺脫intel

個人覺得阿婆這樣的模式是Fabless的最佳典範, 通包且築高牆

我覺得不可能是 full customized..頂多 floorplan 調一
下..placement 調一下..

全部自己來的最佳典範....XD

不意外.... structural placement
