Inside the iPhone 5s | Chipworks Blog.

Wow, I didn’t think that Chipworks will publish such a detailed tear down for free.

Most interesting takeaway for me is the M7 co-processor that is supplied by NXP. It monitors and processes accelerometer, gyroscope and compass data. This is interesting as the NXP LPC18A1 co-processor is based on ARM Cortex-M3 microcontroller, yet another win for ARM. Big loss for AKM and STMicroelectronics and big win for NXP.

Obviously, the most important part of the iPhone 5S is the A7 SoC which has a quad-cord GPU cluster using Imagination Technologies PowerVR serious 6. It supports 3MB of SRAM for the fingerprint sensor, pretty amazing.


What’s the Difference Between Product and Project Management? |

Guest Post: What’s the Difference Between Product and Project Management? |.

I am sure I am not the only product manager who has been asked the question: “What is the difference between Product Manager and Project Manager?”. I think the most important difference is the level of involvement of both these positions throughout the product life cycle.

The Product Manager is involved from product conception all the way till the product is obsolete and retired. The Project Manager is involved in the planning of a project (development of product) till the product is launched. The Product Manager is tasked to create value for a product from cradle to grave, whereas a Project Manager is tasked to plan and execute a development project with the appropriate resources, budget and deadline. The level of involvement is deeper for Project Manager during the development phase, but the overall life cycle of the product is handled by the Product Manager.

This article refers to the Project Manager as “Vertical leadership” and the Product Manager as “Horizontal leadership”. I think there is some truth in this definition, though the level of involvement of a Product Manager can also be quite deep and it really depends on the type of development. For new product categories, I believe the Product Manager has to provide guidance and could very well be deeply involved in many decisions which are not part of the Project Manager’s job.

Audi Adds LTE to S3 Sportback

Audi is taking the lead in introducing LTE into connected cars. To enable LTE in the Audi S3 Sportback, a suitable SIM card with a data rate plan needs to be inserted into the MMI navigation plus unit in the car.

The Audi S3 Sportback also supports WLAN and passengers can connect to the hotspot integrated into the car to surf the web while on the go.

Audi brands its connected car as Audi Connect and it is definitely intensifying its efforts to differentiate itself as the Connected Car of choice. Its press release emphasized the seamless use of media stored on a server (data in the cloud) and networking and communications with other cars and transport infrastructure (V2V and V2I communications)

Intel Atom Roadmap

Bay Trail Family of Atom processor

Bay Trail Family of Atom processor

According to the roadmap released by Intel at IDF earlier, it is developing a quad core Z3700 with Intel HD graphics which will support Windows and Android environments. Z3700 will be targeted at Windows Surface devices and Android tablets. Still no sign of any viable processor to compete against Qualcomm Snapdragon 800 or Samsung Exynos Octa.

Cool Iphone 5S Features

No surprises or ground breaking upgrade for iphone 5 users. The flagship iphone 5S does come with new features such as new home button with finger print scanner (touch id), new front facing lens for better facetime experience, image stabilizer, 64-bit A7 processor and dual flash lights for improving image quality in low ambient light environment.

Nothing that will entice iphone 5 users to want to upgrade to the new iphone 5s. As for me, I am a iphone 4S user, so this to me will be a significant upgrade.
