A slave device for IO-Link communication with a master device, wherein the master device and the slave device operate on a common basic timing, the slave device including at least one Universal Asynchronous Receiver Transmitter (UART) module configured to detect an INIT request sent from the master device during communication setup, calculate an actual timing of the master device from the INIT request and correct an initial timing of the slave device to an actual timing of the slave device based on the actual timing of the master device.

A clock tree implementation method, system-on-chip and computer storage medium, being applied to the system-on-chip comprising a core module (10) and an externally connected module (20); an interconnection matrix (12) in the core module (10) is connected to the externally connected module (20) by a bus converting bridge (11) comprising a protocol bridge (111) and a frequency dropping bridge (112); converting a data bus into a first configuration bus (S100) through the protocol bridge (111), the frequency of the first configuration being the frequency of the protocol bridge; converting the first configuration bus into a second configuration bus (S101) through the frequency dropping bridge (112), the frequency of the second configuration bus being the frequency of the configuration bus of the externally connected module.

A communication system with serial ports for automatically identifying device types and communication protocols and method thereof are described. The communication system and method are capable of automatically identifying the device types and communication protocols of interface devices with different serial device numbers which are disposed in the serial port architecture. Furthermore, the drivers are capable of performing a serial communication based on the serial port architecture for matching the device types and communication protocols correspondingly, thereby reducing the development and manufacturing costs of communication system. Moreover, the user of an application program module only needs to provide the device numbers and data control information without the cooperation of hardware circuits and manufacturing technique of the interface devices to complete the automatic control and monitoring tasks of the interface devices to increase the utilization convenience.
