Abstract

Abstract:
Intelligent modems used in military messaging over IP networks require flow control
mechanism to prevent overflow of data into its buffers. We contribute for a complete flow
control mechanism with built in UART module. All modules are designed using VHDL
design entry. All modules are simulated, synthesized then integrated, and downloaded on an
FPGA. Timing Simulation results found to be matching with the hardware results obtained
from the logic analyzer.
