摘要
围绕通用异步发送和接收 (UART)芯片IMP1 6C5 5 4,对TMS32 0C31芯片如何与外界进行多串口的异步通信给出了一种较为可行的电路设计 ,重点阐述了对芯片IMP1 6C5 5 4的初始化编程设置及其基于先进先出 (FIFO)查询工作模式的接口编程设计。
TMS320C31 is a floating point DSP chip from Texas Instruments and it’s widely used to design the circuit for multi-ports UART (universal asynchronous receiver and transmitter )communication with the chip. Employing the UART chip IMP16C554,this paper provides such a design. It also analyzes the initialization programming for UART in detail and puts forward an interface program design based on a FIFO inquiring operation mode for IMP16C554.
