摘　　要：对 8mm战场侦察雷达中的ADSP - 2 10 6 0和计算机并口的高速数据传输的电路设计问题进行研究。利用新型计算机并口技术EPP(增强型并口 )及先进先出存储器进行设计。该电路设计实现了ADSP - 2 10 6 0和计算机并口之间的高速传输 ,同时该电路具有占用ADSP - 2 10 6 0和计算机时间少的特点。该电路设计已成功地应用到8mm战场侦察雷达信号处理系统中 ,且可以应用到利用并口进行通讯的其它课题中。In this paper, the high-speed data transmission between ADSP-21060 and parallel port for an 8mm battlefield surveillance radar is studied. Enhanced parallel port (EPP) and FIFO memory are used to accomplish block data transfer. The circuit designed has realized high-speed data transmission between ADSP-21060 and parallel port and needs shorter time than SPP mode. This circuit has been applied to the signal processing system for an 8mm battlefield surveillance radar, and can be used for other practical systems in which parallel port is needed for data transmission.
