Based on ARM-architecture of the new generation A6 processor in the iPhone 5

Presenting the iPhone 5 on Wednesday, the company Apple, without going into technical details, stated that the new smartphone is built on a processor A6, which is twice as fast than A5 in the iPhone 4S, as well as for general and graphics performance. Crystal size with steel for 22% less. Moreover A6, despite an increase of up to 4 inches of screen and module LTE, and provides prolonged autonomy. As Apple do it?

 

As it became known to increase the performance of the chip is partly achieved by switching from 45 - to 32-nanometer production technology. Furthermore A6 processor that has two processing cores, made on the architecture of a new generation of ARM Cortex-A15.

Thanks to the "finer" process technology and application architecture Cortex-A15 company managed to provide long battery life phones: Up to 8 hours of voice data on 3G, up to 225 hours on call waiting and up to 40 hours of music playback.

Cortex-A15 architecture involves the ability to create chips with 1, 2, 4, 8, and possibly 16 cores. Clock frequency can be varied from 1.0 to 2.5 GHz. Unfortunately, data on the frequency used in the iPhone 5 processor yet, but it is clear that they are not too high to avoid high power consumption.

So incredibly optimistic disposition raises power and strength of the iPhone 5, which is to negotiate until the fall of 2013, Apple was the first one who released the finished product is a microprocessor architecture Cortex-A15. The rate is already done for the last four Nvidia Tegra, TI OMAP5 and Samsung Exynos 5, but these systems are not yet appeared. Qualcomm offers 28-nanometer chips for Snapdragon S4 Krait-micro-architecture similar Cortex-A15.

The amount of RAM iPhone 5 has traditionally not disclosed fashion by excess technical details, which is common among computers, should not be repeated in the world of smartphones. It is believed that this volume has doubled to 1 GB.

Apple A6: a reference to a quad-core processor in iOS 5.1

The site 9to5mac , to whom we owe many discoveries in the test versions of IOS just made ​​a new discovery. Delving into the internal files of the latest beta of iOS 5.1, the team found the site in the software that manages the operation of these hearts a reference to a Quad-Core (4 cores). The number 0 indicates the presence of one heart (the chip A4), then the number 1 for two hearts (A5 chip on the second image), and 3 points then the possible use of four cores.

It's not really a surprise for many weeks the rumors have reported the arrival of a chip with four cores A6. The screens retina is fairly resource intensive, it is essential to have a more powerful processor on the iPad 3 not to lose fluidity.

Production of quad-core processors instead of Apple A6 Samsung started TSMC

Company Taiwan Semiconductor Manufacturing Co., Ltd (TSMC) has launched a test production of mobile processors A6. Thus for the release of 28-nanometer chips next generation Samsung will be responsible instead of the Taiwanese TSMC.

As the Taiwan Economic News, count on the fact that these processors will appear in the iPad the third generation is impossible. According to the manufacturer, the chips do not go into mass production until the second quarter of next year.

Characteristics of A6 were not disclosed, although it is introducing a new chip graphics processor PowerVR Series 6, capable of much better graphics performance than the current A5. It is assumed that the A6 will be the first quad-core mobile lineup in Apple, becoming the heart of the sixth generation of smartphones iPhone, expected in 2012.

Information Publishing podverzhdaet early information that provided Reuters in July . Both agree that the news - the final version of the A6 processors appear in the middle of 2012.

In late June  it was reported that Apple chose to deny service to Samsung in the production of chips for A6 litigation has been pending since April 2011. The fact that Apple chose TSMC as the provider may cause a blow to Samsung profits , which share components in the iPhone 4, for example, is 26%.

Recall, the two companies accused each other of patent infringement. In its claims against Samsung Apple  claims that smartphones and Tablet Galaxy line of copy iPhone and iPad. Samsung's answer states that the company Steve Jobs illegally uses its development in telecommunications. Apple last success in this field was the  prohibition of sales of tablet Samsung Galaxy Tab 10.1 in Europe.
