As shown in fig. 1, an embodiment of the present invention provides a system for data transmission, where the system includes:
a transmission device 100 for determining a format used for transmission according to a format used for data calculation by a reception device; transmitting data to the receiving device according to the determined format adopted for transmission;
a receiving device 101, configured to receive data sent by a transmitting device; determining a data calculation mode according to a format adopted by transmission equipment; and calculating the received data according to the determined data calculation mode.
When the embodiment of the invention is used for data transmission, the transmission equipment and the receiving equipment are required to be matched with each other.
Firstly, a transmission device sends data to be transmitted to a receiving device, wherein the transmission device needs to determine a format adopted by transmission before sending the data to the receiving device.
Specifically, the transmitting device determines the format used for transmission according to the format used for data calculation by the receiving device.
When determining the format adopted for transmission, the transmission device according to the embodiment of the present invention has multiple determination modes, which are listed below.
Determination method 1: and the transmission equipment determines the format adopted by transmission as the format adopted by the receiving equipment for data calculation.
If the format of the data to be transmitted by the transmission device is 16-bit binary, and the format used by the receiving device for data calculation is also 16-bit binary, the current data format of the transmission device and the format used by the receiving device for data calculation are both 16-bit binary, so that the transmission device can determine that the format used for transmission is 16-bit binary.
Determination mode 2: and the transmission equipment determines the format adopted by transmission as the minimum unit format of the format adopted by the receiving equipment for data calculation.
If the format of the data to be transmitted by the transmitting device is 16-bit binary, and the format adopted by the receiving device for data calculation is 32-bit binary, the current data format of the transmitting device is not consistent with the format adopted by the receiving device for data calculation, so that the transmitting device can determine that the format adopted for transmission is the minimum unit format of the format adopted by the receiving device for data calculation.
After the transmitting device determines the format in which to transmit. And the transmission equipment transmits data to the receiving equipment according to the determined transmission format.
And if the transmission equipment transmits data through the determination mode 1, directly transmitting the data in the transmission equipment to the receiving equipment.
If the transmission device transmits data in the determination mode 2, it needs to determine the minimum unit format of the format used by the receiving device for data calculation, and then change the current data format of the transmission device into the minimum unit format used by the receiving device for data calculation, and then transmit the data.
As shown in fig. 2, assuming that the format of data to be transmitted by the transmitting device is 16-bit binary, and when the format adopted by the receiving device for data calculation is 32-bit binary, it may be determined that the minimum unit format of the format adopted by the receiving device for data calculation is 8-bit binary, so that the 16-bit binary data in the transmitting device is split into 8-bit binary data, and finally the transmitting device transmits the split 8-bit binary data to the receiving device.
By the method, the transmission format is determined by two modes of format selection adopted by the receiving equipment for calculation, and can be selected according to actual conditions, so that the adaptability is stronger.
After the transmission device sends data to be transmitted to the receiving device, the receiving device receives the data sent by the transmission device, and then the receiving device needs to determine a format used for data calculation.
Specifically, the receiving device calculates the received data according to the determined data calculation method.
When determining the format used for data calculation, the receiving device according to the embodiment of the present invention has multiple calculation modes, which are listed below.
Calculation method 1: and if the transmission format of the transmission equipment is the format of the receiving equipment for data calculation, the data calculation mode is direct calculation.
If the format of the data transmitted by the transmission device to the reception device is 16-bit binary, and the format adopted by the reception device for data calculation is also 16-bit binary, the format of the data received by the reception device is consistent with the format adopted by the reception device for data calculation, so that the reception device directly calculates the received data.
Calculation mode 2: and if the transmission format of the transmission equipment is the minimum unit format of the format adopted by the receiving equipment for data calculation, the data calculation mode is calculation after combination.
If the format of the data transmitted by the transmission device to the reception device is an 8-bit binary system, and the format adopted by the reception device for data calculation is a 32-bit binary system, the format of the data received by the reception device is not consistent with the format adopted by the reception device for data calculation, and the format of the data received by the reception device is the minimum unit format of the format adopted by the reception device for data calculation, so that the reception device calculates the received data after combining the received data.
After determining that the data calculation mode is the combined calculation, the receiving device needs to combine the received data according to the format adopted by the receiving device for data calculation.
As shown in fig. 3, the format of the data transmitted to the receiving device by the transmitting device is 8-bit binary, and when the format adopted by the receiving device for data calculation is 32-bit binary, the data format received by the receiving device can be determined to be the minimum unit format of the format adopted by the receiving device for data calculation, so that the 8-bit binary data received by the receiving device is combined into 32-bit binary data, and finally the receiving device calculates the combined 32-bit binary data.
According to the method, whether the format adopted by the transmission equipment for transmission is consistent with the format adopted by the receiving equipment for data calculation or not is determined, or whether the format adopted by the transmission equipment for transmission is the minimum unit format of the format adopted by the receiving equipment for data calculation or not is determined, so that two calculation modes are selected according to the determination result, and the adaptability is higher.
