Abstract
A smart device with no AP includes: a central processing module for running an operation system and applications; a peripheral control module for connecting peripherals; and a message mechanism connected with the central processing module and the peripheral control module for transmitting messages therebetween. According to a preferred embodiment of the present invention, data transfer is provided by a shared memory of the two modules, and the messages simulate data exchanges in a USB transfer layer for connecting the peripherals to the central processing module as a USB compound device. The present invention disperses complexity of hardware and software of the smart device to the two modules for being provided easily. General CPU manufacturers and mobile phone chip manufacturers can avoid the complexity of AP with the present invention for easily joining a competition of the smart device such as a smart phone.
