摘要
数字信号处理器由于具有高性能和灵活可编程的优点而得到广泛的应用。在许多应用系统中 ,一般采用 PC机作主机、DSP作从机的方式 ,实现 DSP与 PC机之间有效可靠的通讯是系统设计的重要部分。介绍了几种 DSP与 PC机串行通信的软硬件方案 ,并对各种方法的优点和缺点进行了比较。
Digital signal processor has been widely used for its high performance and flexible programming ability. In many application systems, the DSP serves as co-processor and PC acts as main processor. It is important to realize communication between DSP and PC in an effective and reliable way during system design. Several methods to realize serial communication between digital signal processor and personal computer, including both the hardware and software, are described in the paper. The advantages and disadvantages of each method are also discussed and compared.
