Embodiment Construction

[0048] When the data transmission rate is high, for example, the data transmission rate is greater than 10 Gbps, the SI of the parallel data output by the deserializer is generally poor. In order to improve SI, the deserializer needs to have an equalization function. The deserializer with equalization function can equalize the serial data according to the equalization algorithm. Then, the deserializer with an equalization function can convert the equalized serial data into parallel data. Wherein, the equalization process may adjust the characteristics of the data transmitted through the transmission channel, so that the data transmitted through the transmission channel has characteristics opposite to the characteristics of the transmission channel. The equalization process can be used to reduce or eliminate the intersymbol interference of the transmitted data caused by the characteristics of the transmission channel. The equalization processing may be Continuous Time Linear ...

Abstract

The invention discloses a data storage method and a deserializer. The data storage method comprises: the deseriallizer performs first equalization processing on first serial data according to a first equalization algorithm in order to obtain first equalization data; the deserializer determines a first quality parameter of the first equalization data; the deserializer performs second equalization processing on second serial data in order to obtain second equalization data according to a second equalization algorithm; the deserializer determines a second quality parameter of the second equalization data; and the deserializer stores a first equalization parameter of first equalization processing, a first equalization algorithm identifier, the first quality parameter, the second equalization parameter of second equalization processing, an identifier of the second equalization algorithm and the second quality parameter. Through the technical scheme of the data storage method and the deserializer, the data for positioning the problem of the deserializer can be obtained and the problem of the deserializer can be positioned.

Description

technical field [0001] The embodiments of the present invention relate to the electronic field, and in particular, to a data storage method and a deserializer. Background technique [0002] SerDes includes a serializer (English: Serializer) and a deserializer (English: Deserializer). Serializers are used to convert parallel data into serial data. A deserializer is used to convert serial data into parallel data. [0003] When the data transmission rate is high, for example, the data transmission rate is greater than 10 gigabit per second (English: gigabit persecond, referred to as: Gbps), the signal integrity (English: Signal Integrity, referred to as: SI) of the parallel data output by the deserializer Usually worse. Therefore, in order to improve SI, the deserializer needs to have an equalization function. The deserializer with an equalization function can be used to firstly perform equalization processing on the serial data by using a certain equalization algorithm, an...
