Portable Wireless Interface Bypassing CPU for Direct Data Access

Solution Overview

Problem

Current mobile communication devices experience slowed processing speeds and high power consumption when notebook computers access wireless Internet through mobile phones due to lengthy data transmission paths and the need for CPU and OS involvement in data processing and format conversion.

Innovation Solution

A portable electronic apparatus with a wireless module, micro processing unit, determining circuit, and control circuit that selectively connects the transmission interface of either the first controller or the wireless module to a designated device based on the device's requirements for wireless communication and data access functions, allowing direct use of wireless communication functions without CPU processing.

Core Design Contradiction:

ProductivityVSSpeed

Solution Approach 1:

The patent extracts the wireless communication function from the mobile phone's main system by providing a dedicated transmission interface that connects directly to the wireless module, bypassing the CPU and operating system. This extraction creates a separate data path that eliminates the need for CPU processing and format conversion, thereby resolving the contradiction between achieving wireless Internet access and maintaining fast data processing speed.

AI summary

A portable electronic apparatus consists of a wireless module, a micro-processing unit, a determining circuit, and a control circuit. The wireless module provides a wireless communication function, and a first controller of the micro-processing unit provides a data access function. When a designated device is coupled to the portable electronic apparatus, the determining circuit determines whether to use the wireless communication function and whether to use the data access function in order to generate a determining result. The control circuit selectively connects a transmission interface of the first controller or a transmission interface of the wireless module to the designated device according to the determining result. When the control circuit connects the transmission interface of the wireless module to the designated device, the portable electronic apparatus is simulated as a wireless communication product.
