DSP 处理器 XINTF 接口与液晶并口的兼容通信设计
Design of compatible communication between DSP′s XINTF interface and LCD parallel port
摘要
Abstract
Low process efficiency,and more occupled port resources which can not be reused are problems in the compatible parallel communication.In order to solve the problems,I/O port of DSP is used to imitate parallel port.A logic gate circuit or a programmable logic device was pro-posed to make XINTF interface compatible to LCD parallel port.By using the logic analyzer and DSP processor,the degree of the improved timing sequence and timing requirement is observed, and the compatible parallel communication system between XINTF interface of DSP and LCD parallel port can be implemented,the experiment results confirm the correctness,feasibility and flexibility of the program.关键词
