DEVICE INCLUDING DIGITAL INTERFACE WITH MIXTURE OF SYNCHRONOUS AND ASYNCHRONOUS COMMUNICATION DIGITAL PROCESSING SYSTEM INCLUDING THE SAME AND METHOD OF DIGITAL PROCESSING PERFORMED BY THE SAME

摘要

The present invention relates to a device including a digital interface in synchronous and asynchronous mixing type, a digital processing system including the same, and a digital processing method conducted by the same. The digital processing system includes a master chip and a first slave chip. The master chip includes a first clock pin and a first data pin. The first slave chip includes a second clock pin and a second data pin. A first transmitting operation for transmitting first data from the master chip to the first slave chip provides a first clock signal outputted through the first clock pin together with the first data outputted through the first data pin, and is conducted based on a synchronous type for synchronizing the first data with the first clock signal and transmitting the same. A first receiving operation for transmitting second data from the first slave chip to the master chip is conducted based on an asynchronous type for transmitting the second data outputted through the second data pin regardless of the first clock signal. Therefore, the digital processing system including the digital interface in the synchronous and asynchronous mixing type can be realized in a simple structure.
