Title:
DATA TRANSMISSION CIRCUIT, CHIP AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2023/019594
Kind Code:
A1
Abstract:
Embodiments of the present application provide a data transmission circuit, a chip and a terminal, which relate to the technical field of integrated circuits. According to a first identification signal and a second identification signal, it is detected whether an error occurs when a data signal is transmitted in a FIFO circuit. The data transmission circuit comprises an FIFO circuit, an identification generation circuit, a comparator, a data generation circuit, and a data receiving circuit. The data generation circuit may write a data signal to the FIFO circuit, and at the same time, the identification generation circuit may write a first identification signal to the FIFO circuit. Then, under the control of a read enable signal, an identification comparison circuit receives the first identification signal read by the FIFO circuit and a second identification signal generated by the identification generation circuit, and the data receiving circuit receives the data signal read by the FIFO circuit. The identification comparison circuit may indicate, on the basis of the first identification signal and the second identification signal received under the action of the same read enable signal, whether an error occurred when the data signal is transmitted in the FIFO circuit.
