| 摘 要： | 随着数字信号处理速度的提高，传统的串口，并口已不能满足主机与DSP之间的高速数据传输要求，因而，介绍了一种基于TMS320C5402DSP和CY7C68013的UStE．0系统。利用FPGA进行I／O口的扩展，克服了I／O口功能弱的缺点，提高了DSP的控制能力。实验表明，该系统具有速度快，可靠性高的优点。

| Abstract: | With the increase in the speed of digital signal processor(DSP),serial and parallel ports can't meet the demand of high-speed data transmission between computer and high-speed DSP.A system on the basis of TMS320C5402 and CY7C68013 is presented.By using FPGA to expand the I/O interface,the weakness of DSP I/O interface function is improved and the capacity of DSP control is enhanced.Through experiments,it is shown that the system is rapid and reliable. |
