NIOS II soft-core processor based wireless notice board

Abstract

This paper is about the development of GSM based Wireless Notice board using Altera NIOS II softcore processor system. In today's world the transfer of information is seen that important notices takes time to be displayed on the notice boards as the person has to go physically to display the desired message on the Notice board. We have designed an embedded soft-core based system to solve this problem. Here embedded system on peripheral chip (SOPC) reconfigurable system receives SMS's from several authenticated mobile users and display's the message on the Notice Board. The implementation of the interface with GSM Modem and Liquid Crystal Display (LCD) was carried out using NIOS II soft-core system running on Altera FPGA DE2 board having target as Cyclone II EP2C35F672C6. The designed NIOS II processor based wireless notice board has various applications in several domains including public advertisements and educational sectors i.e in schools and colleges to update and display messages in real time from any geographical location of the user which reduces manual operation.
