| Abstract: | The article uses open source EMSIM (Embedded StrongARM Energy Simulator) to implement the simulation of embedded hardware. Firstly, it discusses the design of EMSIM and elaborates the design and implementation of UART (Universal Asynchronous Receiver/Transmitter) detailedly, then puts forward the improvement of UART simulation. Finally, the embedded operating system Linux runs successfully on EMSIM, and the test of UART, which validate that the design and implementation of UART is correct. |
