The universal asynchronous receiver/transmitter (UART) is an old friend to embedded systems engineers. It's probably the first communications protocol that we learn in college. In this article, we ...

The system has an FPGA-based CPU written in Verilog. It runs on a Nexys-3 board and features PS/2 Keyboard input, a VGA output with a VHDL VT100 terminal emulation module, access to the Flash and ...
