Design and Implementation of a Cloud-Based Software Platform for Dynamically Reconfigurable Wearable Computers

Abstract

As a support platform for new Internet services, the cloud computing (CC) platform serves both end users and service providers, and also provides technical support for the development of some emerging technologies. This paper designs and implements a dynamic wearable computer software platform based on the CC platform, including writing a dynamic reconfiguration management module, developing a CPLD driver, an FPGA driver, a dynamic link module and a configuration file download module; building a graphical desktop manager, which provides a graphical management interface for the wearable computer and specifies the packaging form of the application; developing a GPS resolution module, which provides upper layer applications to provide GPS positioning information; build the communication subsystem on the software platform, do some research on heterogeneous network communication, and provide functions such as authentication, permission management, message sending and information encryption on top of network communication. The encryption and decryption module is accelerated by the hardware encryption function provided by the dynamic reconfigurable (DR) module, and the usability of the DR wearable computer software platform is verified.
