Design And Implementation Of Wearable Dynamic Reconfigurable Platform Based On Zynq

In recent years,the level of chip technology has been continuously improved,and various kinds of low-power and high-performance processors have been continuously improved.These advances in technology have enabled the wearable device hardware to be reduced in size while enabling a large number of task calculations.In life,a variety of wearable devices have also been sought after by people,such as watches,wristbands,glasses,etc.have become part of life,play a role that can not be ignored.However,people gradually put forward more demands on wearable devices,such as more complex application environments and more flexible hardware configurations,which have brought new directions to the development of wearable devices.If the wearable device has a single communication method,there is not enough external communication interface for data interaction.There aren't many kinds of computing tasks that a wearable device can handle.The main reason is that the wearable device is small and the onboard hardware resources are insufficient.This paper analyzed the functional requirements of wearable devices,designs a dynamic reconfigurable platform based on Zynq,and combines the dynamic reconfigurable technology of FPGA based on the shortcomings of small size and low hardware resources of wearable devices.The dynamic reconfigurable platform can provide I/O interfaces and reconfiguration of computing tasks for wearable devices.In the aspect of I/O interface reconstruction,three communication methods such as RS232,RS485,CAN and VGA camera are taken as examples for design,and a storage-based I/O interface dynamic reconfigurable identification scheme is proposed.In terms of computing tasks,this paper analyzes the requirements of wearable device image processing and text encryption and decryption.Combined with the VGA camera in the I/O interface reconstruction,the RTL method is used to implement the image edge detection calculation task to process the image in real time.For text encryption and decryption,the DES encryption and decryption algorithm is implemented using the HLS method.The wearable device can obtain the results of the computing task processing from the reconfigurable platform.Experiments show that the dynamic reconfigurable platform can provide the task of reconfiguration and I/O interface reconfiguration for wearable devices.The dynamic I/O interface identification scheme designed in this paper enables a dynamic reconfigurable interface to be able to External devices communicate data.The dynamic reconfigurable platform has good versatility and can be implemented on various Zynq chips.The reconstruction of I/O interfaces and the reconfiguration of computing tasks are very extensible,achieving improved hardware resource utilization and being wearable.The device provides the purpose of extending the interface and computing resources.
