Abstract
A semiconductor device capable of improving the efficiencies of communication systems is provided. The semiconductor device comprises: an open period in which reception of data or transmission is allowed; a clock generation circuit defining a close period in which transmission of data and reception are not allowed; and a TSN controller connected to the clock generation circuit and performing transmission of data or reception, wherein the TSN controller performs semiconductor device or reception at another time than open period.
Claims18
A semiconductor device, comprising:
- a clock generation circuit supplying time information;
- and
- a controller inputting the time information, and transmitting or receiving data,
- wherein the semiconductor device is permitted reception or transmission of the data during an open period, and is not permitted transmission or reception of the data during a close period,
- wherein the open period and the close period are determined by the time information,
- wherein the controller starts the transmission of the data earlier than a start of the open period, and
- wherein the controller starts the reception of the data later than the start of the open period.
A communication system comprising:
- a first device connected to a first bus;
- and
- a second device connected to the first device via the first bus,
- wherein the first device comprises;
- a first clock generation circuit supplying time information;
- and
- a controller inputting the time information, and
- transmitting or receiving data,
- wherein based on the time information, an open period and a close period and are determined,
- wherein first device is permitted reception or transmission of data during the open period, and is not permitted transmission or reception of the data during the close period,
- wherein the controller starts the transmission of the data earlier than a start of the open period, and
- wherein the controller starts the reception of the data later than the start of the open period.
A method for controlling a communication system:
- a first device;
- and
- a second device coupled to the first device via a bus,
- wherein the first device comprises:
- a first clock generation circuit defining an open period in which data reception or transmission is permitted and a close period in which data transmission or reception is not permitted;
- a delay time setting unit;
- and
- a controller performing transmission or reception of data in a period other than the open period based on time information set in the delay time setting unit,
- wherein the second device comprises:
- a second clock generation circuit defining an open period in which data reception or transmission is permitted and a close period in which data transmission or reception is not permitted,
- a training step for determining the time information set in the delay time setting unit;
- and
- an operating step in which transmission of data or reception of data is performed between the first device and the second device after the training step.
