Apple Secures A Patent For A-Series Processors

Posted on Dec 18 2012 - 4:54pm by Muhammad Umer

U.S. Patent and Trademark Office (USPTO), has granted Apple the authorship of an important patent on the production of SoC (system-on-chip) for the protection of A-Series processors, present in all the latest mobile devices from Cupertino.

The patent granted to Apple is the No. 8,334,704 and is titled “Systems and methods for providing a system-on-a-substrate”. This protects the authorship of the basic functions of A-Series family, present in mobile devices, such as Apple iPhone, iPod touch and iPad.

A SoC (system-on-chip) is a processor that has within it all the internal components of a real system for its proper functioning. Within a SoC, in fact, we can find the microprocessor (CPU), the hardware dedicated to graphics calculations (GPU), the RAM and more, such as I / O controller, the chip for wireless communication, the accelerometers.

The patent awarded to Apple today, indicates precisely the possibility of introducing a single chip with full range of hardware listed above.  There are further methods of communication between the various devices inside it to further reduce the space to devote to the same.

The SoC Apple also provide a flexible scheme for the arrangement of the various components inside it, thanks to a flexible printed circuit, called “flex” which may extend over the substrate in order to have the possibility to add additional components. Through this system the memory can be installed above or below relative to the substrate, but still within the same SoC.

This patent was presented by Apple in September 2009, six months before the presentation of the A4 chip, which was introduced with the first iPad, and subsequently inserted on the iPhone 4 and fourth-generation iPod touch.

The A-Series processors currently have obtained their maximum performance with the chip A6X of fourth-generation iPad with Retina Display, thanks to the inclusion of a dual-core CPU (the same as the iPhone 5), a quad-core GPU of latest generation and 1 GB of RAM. All within a single microprocessor!
