Abstract
A data transmission parity device for verifying data transmitted from a first device through a data line to a second device includes a processor and a memory. The data line includes an N number of signal pins for transmitting data and an (N+1)th signal pin for transmitting parity information. The processor is configured to receive and obtain a signal value of the N+1 signal pins, calculate a first sum of the signal value of the N+1 signal pins and apply a first modular operation on the first sum, determine whether a result of the first modular operation is equal to zero, and control the second device to reject the data when the result of the first modular operation is not equal to zero. The first modular operation and the second modular operation are both (mod 2) operations.
