Description
Summary:A portable terminal device is designed for emergency system in an expressway with tollgates. It has three main functions such as printing receipts, taking photographs and short-message-based wireless communication. In emergency situation, the device can take the place of common charge computer system inside check kiosks. Its hardware consists of a FPGA chip, high speed embedded microprocessor, GSM/GPRS module, million pixel camera, cipher card and IC card module. The FPGA chip provides logical connection among memory chips, peripheral modules and microprocessor. Meanwhile, it acts as a communication conversion bridge between SPI pattern and UART pattern because there are not enough UART ports in this microprocessor with a vacant SPI port. The FPGA program in Verilog HDL was verified by RTL simulations successfully.
