| 摘 要： | 论述了微机并行口PS／2模式的工作原理，阐述了软件握手关系，提出了一种高效的增强软件握手关系的设想及其实现方法，实现了单片机与微机并行口PS／2模式的通信，数据传送速率大约是串行通信(115．2kbit／s)速率的15倍，该设计方法对微机与近距离中速外围设备的通信有一定的参考价值。

| Abstract: | The fundamental principle of PS/2 mode of microcomputer parallel port and thesoftware handshake techniques are introduced. A new idea of design and realization methodof efficient enhanced software handshake relationship is proposed. Communication betweenmonolithic processor and microcomputer with PS/2 mode is implemented at data rate about15 times of that of serial communication in 115.2 kbit/s. The design method is valuable forthe communication between microcomputer and short distance and middle rate peripheral e-quipments. |
