Playstation 4 may no Cell processor A
As possible alternatives POWER7, Sandy Bridge and Larrabee processors are traded. The Cell processor can not keep up with the performance of modern graphics cards.

Sony will equip its being developed new games console Playstation 4 may stop with a Cell processor. According to press reports, the manufacturer is currently looking for alternatives.
Besides highly modernized versions IBM Cell Power-7-CPU, x86 processors are based on Sandy Bridge or the failure of a discrete graphics card Larrabee architecture in question.
Integrators of popular high-end graphics cards have, in recent years, which approximated a Cell processor. In particular, the possibility is stressed to handle floating point numbers with double precision (64 bit) - a skill that is not needed for 3D graphics.
Multiple voltage source
One increasingly common request is from a different source to recharge the battery voltage, point is not to voltage source in case of overload to provide this function. Changes in input conditions can be dynamically adjusted when the charge current to achieve this functionality.
For example, mobile users often do not have time to find the AC outlet to recharge their equipment to the contrary, they hope that most of the many electronic devices have a USB port to charge the battery to them, including other battery-powered devices such as laptops. Therefore, the current market, many of the charger chip supports USB communication and input from a single lithium battery charge. At this time the challenge is to provide compensation for the changing USB port power level. As the load changes, the system must control the value of a constant charging current to ensure the normal operation of USB ports.
Some charger chip dual approach supports the use of simple USB operation, the method uses two preset charge current value (usually 500mA and 100mA) to support the USB port to allow the maximum current or the minimum current necessary to ensure the integrity of the port sex. Usually this requires interface logic embedded in the charger chip, so that the system microcontroller can read the USB port on a continuous state, and indicates a charging current from the charger to switch to another charge current.
