What is APU?

APU is also called the application processor, and AMD that the integration of CPU and GPU products are different, this application processor is a low-power central processor based on the expansion of the audio function and special interface of the very large scale integrated circuit, also known as MAP. This application processor is accompanied by smart phones, originally non-smart phones can only make calls and send text messages, its core technology is a voice compression chip, called baseband processor. In addition to communication, smart phones have also added photography, playing video and audio, etc., and the baseband processor has been unable to meet these new features, not to mention the audiovisual quality. In order to achieve these functions, another coprocessor is needed to process these signals, which is the application processor. Application processor plays the role of computing and calling other functional components in intelligent devices, integrating the central processor, graphics processor, video codec, memory subsystem and other modules
