Function-variable portable computer mainboard

Abstract

The invention provides a wearable computer main board with variable functions, which is designed in view of variable application requirements of a wearable computer and the defects of single function, performance upgrade and function extension of the existing technical realization methods. Chips such as FPGA / CPLD / FPAA, and the like with overprogram characteristics are connected to a plurality of interfaces and a bus line of the wearable computer main board, and the FPGA / CPLD has a restructural function on the board by the overprogram characteristics according to the customization of multiple function requirements. Original hardware change such as chip replacement, device replacement, and the like is converted into software change with rewritten content reset by an IP core. The wearable computer main board can be upgraded easily so as to shorten development period, improve applicability and reduce development cost.

Description

technical field [0001] The invention belongs to the field of electronic information, relates to electronic engineering technology and computer technology, in particular to a wearable computer motherboard with variable functions. Background technique [0002] Wearable computing is an emerging computing technology that is in a period of rapid development. Wearing the computer on the user's body is a means to realize the close coupling between man and machine, and strive to make the computer provide physical and intellectual assistance and enhancement for people more naturally. [0003] The components of general personal computers have been developed very maturely, but wearable computers cannot use general PC components due to their special requirements in terms of wearability, power consumption, and human-computer interaction characteristics. Notebook PCs and ultra-mobile PCs (UMPC / MID) for general portable use are different. [0004] At present, there are no standards for we...

Problems solved by technology

[0008] The purpose of the present invention is to propose a wearable computer motherboard with variable functions for the changeable application requirements of wearable computers and the shortcomings of single function, performance upgrade and function expansion in the prior art implementation methods. Chips with reprogrammable features such as / CPLD / FPAA are connected to various interfaces and buses of the wearable computer motherboard. Using their programmable features, they can be customized for various functional requirements, so that FPGA / CPLD can be reprogrammed on the board. Structural function, transforming the original "hardware change" (replacing chips, devices, etc.) into "software change" (IP core reset content rewriting), easy to upgrade, to shorten the development cycle, improve applicability, and reduce development costs
