摘要： [Object]
To efficiently perform serial communication.
[Solving Means]
A communication device includes a controller that determines a timestamp to be used as a start point and a unit period of the timestamp starting from the start point, an encapsulator that samples, in synchronization with the timestamp in each unit period, a GPIO (General Purpose Input/Output) signal supplied from a Master, by a fixed sampling period or at a sampling period corresponding to a frequency of a logic change of the GPIO signal and generates a predetermined communication protocol packet including the sampled data, and a LINK that transmits the packet to a communication counter device.-

摘要： [Problem] To provide a communication device and a communication system that performs serial communication with low power consumption and high speed.
[Means of Solution] A communication device includes: a state switching control unit that controls switching between a first state in which synchronization is established for communication with a communication partner device, a second state in which the communication is started after the synchronization is established in the first state, a third state in which the communication is intermittently stopped without disestablishing the synchronization, and a fourth state in which the communication is stopped for a longer period than the third state and when the communication is resumed, synchronization is re-established with the communication partner device; a first communication control unit that repeats in a first cycle an operation of continuously transmitting to the communication partner device a first signal during a first signal section in the fourth state; and a second communication control unit that, when receiving a second signal output from the communication partner device in response to the first signal, transmits a third signal synchronized with the second signal to the communication partner device. When the second communication control unit transmits the third signal, the state switching control unit causes the communication device to transition from the fourth state to the first state.-

摘要： To efficiently perform data communication.
A communication device includes a LINK that performs protocol conversion of a signal from a Master and outputs the converted signal to a Slave SerDes, and performs protocol conversion of a signal from the Slave SerDes and outputs the converted signal to the Master. The LINK is capable of alternatively selecting a first mode and a second mode when transmitting the signal from the Master to the Slave SerDes. In the first mode, the LINK converts a 1-byte signal transmitted from the Master into a signal of a first communication standard in units of the 1-byte signal and transmits the converted signal to the Slave SerDes, then receives a signal of the first communication standard including an ACK signal representing an acknowledgement or a NACK signal representing a negative acknowledgement, and converts the received signal into a signal of a second communication standard and transmits the converted signal to the Master.-
