Abstract

The present invention discloses a signal processing method and apparatus. According to the signal processing method, phase change processing can be performed on to-be-sent data signals according to a phase status of a data synchronization signal and phase statuses of the to-be-sent data signals, so that phase differences between a majority of to-be-sent data signals in the processed to-be-sent data signals and the data synchronization signal meet a certain condition, thereby reducing a volume of coupling crosstalk, generated by the to-be-sent data signals, on the data synchronization signal and further reducing impact of SSN on a system.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a signal processing method and device. Background technique [0002] Double data rate (DDR for short) synchronous dynamic random access memory (SDRAM for short) is currently the most common and general type of memory, which may be called DDR for short. Since DDR has the function of double data flow, it has been widely used in electronic equipment in various industries. [0003] With the rapid development of hardware and network technology, users have higher and higher requirements for the packaging and integration of DDR chips and controller chips. This leads to synchronous switching noise (simultaneously switching noise, SSN for short) generated during signal transmission during data interaction between the DDR chip and the controller chip, thus affecting the reliability of the DDR interface. [0004] In the prior art, in order to reduce the impact of S...
