介绍了DSP与慢速设备接口的一种时序转换方法。通过该方法,可以解决DSP与传统输入输出设备时序不匹配的问题熏从而实现DSP与8080、6800等时序兼容的或其它慢速读写周期的输入/输出设备的直接连接,如液晶显示模块、打印机、键盘等。这种时序转换方法能使DSP在工业控制和测试设备中获得更加广泛的应用。
A method of timing conversion between DSP and slow device interface is introduced. The method can solve the problem that the DSP does not match the timing of the traditional I / O devices. Thus, the direct connection between the DSP and the input / output devices with time-compatible DSP or other slow read / write cycles, such as the liquid crystal display module, Printer, keyboard and so on. This timing conversion method enables DSP to be more widely used in industrial control and test equipment.
