发帖数: 41892 | 2 目前英文日文press release都没提自己设计。
以前尼康对自己有设计的机型从未发生过这种事。
正常推论这次应该不会例外。
另外D3-D3100业界普遍猜测是Renesa生产，Renesa自己也是有设计的。
所以存在Renesa应耐克要求设计生产的可能
最靠谱的办法就是等chipworks teardown -- 不知道chipworks舍不舍得买个D4拆了。
看看上面有没有nikon logo

发帖数: 2210 | 4 DPR转了篇 ifixit 的 e-pl7 teardown. 主板上用的图像处理器上面赫然印着
Panasonic的牌子。
边上的内存芯片我查了一下，是一片 4Gb ddr3L sdram.
奥巴的色彩一直让人讨喜，也比较独特。图像处理器硬件对直出色彩风格影响是很大的
。不知道奥巴怎么用松下的硬件调出了自己独门的色彩。
另一个角度，松下机器说不定改一改机内曲线能复制奥巴的直出风格。 |

所以等teardown出来之后肯定会发现里面2/3都是电池。 |

，一层一层剥下去还挺麻烦吧。
国内这方面很强，reverse engineering比较适合搞山寨，哇哈哈 |

没听说过TI做电池啊。我被你吓得觉得自己孤陋寡闻，还真去TI网站查了一下，没有啊。
还有，iPhone 3GS根本没有任何一个chip是TI的。各种teardown analysis很清楚的。
你这个30%是哪儿来的啊？iPhone 4我不信会用到什么TI的chip。 |

发帖数: 108 | 14 iPhone 4 天线终于还是出现了问题。
事实上，从我的teardown 分析，以前的iPhone， 与同类产品比，射频收发一直存在问
题（包括天馈系统）。但是大家都把问题归结于AT&T 的网络性能。而AT&T 出于某种考
虑，也不愿意blame 苹果的设计。为了赚钱，bear it and eat it 吧.
IPhone 4 的天线问题，说到底是一个设计上的大缺陷，不可完全修复，但可改善。从
engineering 的角度来说，Jobs 说这个design是 “brilliant engineering”, 我要
说是“engineering failure.” 很显然，APPLE 的工程师没有对天线性能在各种使用
情况和环境下进行考虑和严格测试。或者他们可能太注重fancy和cool，而有意牺牲
quality? 这种情况放在任何一个好的通讯公司，是不可理解的 （特别是从第一代
iPhone 到现在都有的缺陷）。
人体是由有导电性和损耗性的tissue 和 fluid 组成。它的介质特性，如有人提到的，
会de-tune 天线的谐振。比如说天线本来谐振在1900MHz, 此 |

The new A5 processor used by iPad 2 incorporates Samsung's new 46nm Low
Power DDR2 memory, uses a
variable clock speed and costs about $25, a significant premium over NVIDIA'
s competing Tegra 2.
According to research performed by UBM TechInsights, Apple's larger A5 (12.
1mmx10.1mm, compared to
the 7.3mmx7.3mm A4) costs about $25 to build, making it $10 more expensive
than similar dual core
chips such as the Tegra... 阅读全帖 |

A forum post at Chinese site WeiPhone offers a photo of what is claimed to
be the iPad 3's logic board showing an "A5X" system-on-a-chip.
Apple is expected to introduce an upgraded processor and graphics package
for the iPad 3, with the assumption being that it would be called the A6
after the A4 initially appeared in the original iPad and iPhone 4 and was
succeeded by the A5 in the iPad 2 and iPhone 4S. But if this photo is to be

It's been a busy week of Apple teardowns for iFixit, with the firm
announcing today that it has completed its work on the non-Retina version of
the Mid-2012 MacBook Pro.
Given that the non-Retina version has retained the same form factor for a
number of years, there are few changes to the internal layout of the
components, but a fresh look inside now that the redesigned Retina MacBook
Pro has been released offers some interesting comparisons of how Apple is
working ... 阅读全帖 |

One of the main criticisms of the new Thunderbolt connectivity standard
embraced by Apple has been its cost, which adds a considerable premium to
the prices of compatible peripherals. Even Thunderbolt cables are expensive
, with Apple's 2-meter cable priced at $49, a price on par with
offerings from the few other companies selling Thunderbolt cables so far.
In a report published earlier this week, Ars Technica took a look at why the
cables are so expensive and ... 阅读全帖 |

发帖数: 5329 | 33 一般情况下，即便RTP session已经建立，Signal仍然需要，维持状态，否则call
controller（like CCM）会teardown连接，当然也有例外在某些特别需求情况下，H323确实需要在signal断掉的情况下继续维持RTP session。另外，通话结束，CCM还需要通知对端关闭session。cs3常用于voice signal QOS，Cisco很少提价cs5，cisco说EF，其实都是IP precedence = 5，常用于voice的RTP traffic。 |
