Abstract

The invention relates to a serial data processing device and a data offset correction method. The serial data processing device comprises an offset detection circuit and an offset correction circuit. The offset detection circuit is configured to store a plurality of symbols, receive a first data signal from a host device, and detect an offset of the received first data signal according to the symbols to generate a correction signal, where each of the symbols includes at least one default logic value, and the numbers of the at least one default logic value of each symbol are different from each other. The offset correction circuit is used for correcting the received first data signal according to the correction signal to generate a second data signal.

Description

technical field [0001] This case is about a serial data processing device, more specifically, about a serial data processing device capable of correcting data offset and its correction method. Background technique [0002] Serial communication interfaces are often found in computer buses or data channels between integrated circuits. In practical applications (especially synchronous transmission applications), the data transmitted through the serial communication interface may be affected by factors such as transmission delay, signal reflection, and the driving capability of the input and output circuits, resulting in the generation of data received by the receiving device. offset. In this way, the receiver device will receive wrong data. Contents of the invention [0003] In some embodiments, the serial data processing device includes an offset detection circuit and an offset correction circuit. The offset detection circuit is used for storing a plurality of symbols, an...
