Embodiment Construction

[0031] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0032] Figure 2A A functional block diagram of an embodiment of the signaling device of the present invention is shown. exist Figure 2A In the process, the sender receives the parallel signal after synchronization, samples the parallel signal, and then converts the parallel signal into a serial signal based on a dedicated algorithm and sends it out. If the sending end also supports receiving signals, it will deserialize the received serial signals based on a dedicated algorithm, and output them as parallel signals after synchronization.

[0033] Figure 2B A functional block diagram of one embodiment of the signal receiving device of the present invention is shown. exist Figure 2B Among them, the receiving end converts serial input into parallel output based on a dedicated algorithm, and ou...

Abstract

The invention discloses a signal processing method and device, SERDES and a processor, relating to the technical field of signal processing. The device is characterized in that a signal transmitting module in the device comprises an oversampling coder connected with a clock generator; the oversampling coder is used for receiving the W-channel parallel input signals and carrying out R-times oversampling coding on the W-channel parallel input signals; a signal receiving module comprises a decoding synthesizer connected with a clock generator; and the decoding synthesizer is used for decoding and R-times combining the parallel signals from a deserializer to obtain the W-channel parallel input signals. According to the invention, when the functions of the SERDES are completed, such function modules as the clock recovery circuit can be omitted, thus simplifying the function modules of the SERDES process or chips and realizing a smaller size.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a signal processing device, method, SERDES and processor. Background technique [0002] With the increasing demand for information flow, the traditional parallel interface technology has become a bottleneck for further increasing the data transmission rate. The serial communication technology SERDES is replacing the traditional parallel bus and becoming the mainstream of high-speed interface technology. [0003] SERDES is the abbreviation of English SERializer (serializer) / DeSerializer (deserializer). It is a time-division multiplexing (TDM), point-to-point communication technology, that is, at the sending end, multiple low-speed parallel signals are converted into high-speed serial signals, through the transmission medium (optical cable or copper wire), and finally at the receiving end. Serial signals are converted back to low-speed parallel signals. This po...
