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

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
作者: chrispherd (WTF) 2012-09-26 12:37:00
阿婆這樣做就很怪，重點是沒必要自己來。不像AMD需要這
作者: chrispherd (WTF) 2012-09-26 12:38:00
麼辛苦的去賺那少少的$$$
作者: forever215 2012-09-26 12:39:00
Apple 是拿來獨佔市場..跟AMD 拿出去賣的不同..
作者: forever215 2012-09-26 12:40:00
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?
作者: obov (來噓蒼真) 2012-09-26 14:43:00
PA-semi裡面的都是一些老牌cpu咖 當然知道怎麼搞最好
作者: obov (來噓蒼真) 2012-09-26 14:44:00
apple扶持自家原pa-semi團隊的人目的也很清楚阿
作者: obov (來噓蒼真) 2012-09-26 14:45:00
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
