Development of a Reconfigurable Serial Communication Engine Based on UART Protocol

This paper describes a reconfigurable UART engine using Verilog HDL, with separate transmit, receive, timing, shift-register, and FSM-control blocks. Configurable communication parameters can make the interface adaptable to different embedded-system requirements. The supplied screenshots show waveform and schematic views, but detailed performance claims require readable waveforms and verified tests.
