Design, optimization and verification of switch board controller

A serial interface module based on FPGA platform is designed for data communication between the operator console and Fire Control Computer. Various techniques adopted during the design and optimizations are presented in this paper. The module is developed using VHDL language and is integrated onto a SOC to achieve compact, stable and reliable communication. It supports different baud rates. In the optimized design logic, resource consumption is reduced by 11% and power dissipation is reduced by 15%. The verification results indicate that the optimized design can communicate correctly and steadily at typical baud rate of 19200 bits/sec.
