Description

A kind of encoding method, related equipment and system

technical field

The present invention relates to the field of computer technology, in particular to an encoding method, related equipment and a system.

Background technique

The solid-state semiconductor industry reliability standard JESD204 series protocol is a serial interface standard based on the serializer/deserializer (English: SERializer/DESerializer, referred to as: SERDES), which is used to define the ASIC (English: Application Specific Integrated Circuit, referred to as : ASIC)/field programmable gate array (English: Field-Programmable Gate Array, referred to as: FPGA) and digital-to-analog converter (English: Digital to analog converter, referred to as: DAC)/analog to digital converter (English: Analog to digital converter , referred to as: ADC), the topology defined by the JESD204B protocol is shown in Figure 1. Downlink direction: The intermediate frequency data of ASIC/FPGA is transmitted to DAC through the JESD204B interface, and then sent out from the radio frequency air interface after passing through the mixer (English: Mixer) and power amplifier (English: Power Amplifier, referred to as: PA). Uplink direction: The data received from the radio frequency air interface is amplified by a low noise amplifier (English: Low Noise Amplifier, referred to as: LNA), and then converted to an intermediate frequency by a demodulator (English: Demod), and then passed through the JESD204B interface after being sampled by the ADC Transfer to ASIC/FPGA.

JESD204B data is transmitted in units of frames, one frame contains F bytes, and one multiframe (multiframe) contains K frames. JESD204B data consists of three types of data: code-level synchronization (CODE SYNC), initial lane alignment (English: Initial Lane Alignment, ILA for short) sequence, and service data. The structures of these three types of data are shown in Figure 2.

Code-level synchronization (CODE SYNC) consists of continuous control words K (the value is K28.5). The second multiframe of the ILA sequence is composed of control word R (first byte), control word Q, control byte, data and control word A (last byte); other multiframes of the ILA sequence are sequentially composed of control word R (the first byte) 1 byte), data and control word A (last 1 byte). Among them, control word A (value K28.3) is used for multi-lane (lane) alignment, control word F (value K28.7) is used for frame (Frame) alignment (control word F will be introduced later), control word K (value K28.5) is used for code-level synchronization, the control word R (value K28.0) is used to indicate the start of multiple frames in the ILA sequence, and the control word Q (value K28.4) is used to indicate the ILA sequence The beginning of the control word.

In order to improve the transmission characteristics of JESD204B data on the link, it is necessary to insert the control word A or control word F at the end of the data frame of the service data. At present, the data frame can be encoded by 8B10B encoding technology to generate a specific pattern to distinguish Control word A, control word F and common data. As shown in Figure 3, the 8B10B encoding technology is to decompose a group of continuous 8-bit data into two groups of data, one group is 3-bit data, and the other is 5-bit data, which become a group of 4-bit data after encoding. Data and a set of 6-bit data, these two sets of data form a set of 10-bit data. Inserting the control word F or the control word A at the frame end of the data frame includes two situations, and the data frame shown in FIG. 4 is taken as an example below for description.

No scrambling situation: as shown in Figure 5, if the last byte of the current frame (not at the end of the multiframe) is identical with the last byte of the previous frame, then replace the last byte of the current frame with the control word F=K28.7 one byte. If a replacement has already occurred in the previous frame, it will not be replaced this time. If the last byte of the current frame (at the end of the multiframe) is the same as the last byte of the previous frame, then replace the last byte of the current frame with the control word A=K28.3.

The situation of scrambling: as shown in Figure 6, if the last byte of current frame (not the last frame of multiframe) is equal to 0xFC (being D28.7), then replace the last byte of current frame with control word F=K28.7 one byte. If the last byte of the multiframe is equal to 0x7C (ie D28.3), then use the control word A=K28.3 to replace the last byte of the current frame.

The defect of the prior art is that the coding efficiency of 8B10B technology is 0.8, which requires relatively high SERDES rate and SERDES logarithm.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

Please refer to FIG. 7 . FIG. 7 is a schematic flowchart of an encoding method provided by an embodiment of the present invention. The method includes but is not limited to the following steps.

Step S701: the encoding terminal judges the frame type of the target JESD204 frame in the JESD204 data to be transmitted.

Specifically, the JESD204 data specifically refers to data based on the JESD204 series protocols, for example, the relatively mature JESD204B protocol currently used, the JESD204C protocol that may evolve in the future, and the like. Taking the JESD204B protocol as an example, the JESD204 data to be transmitted consists of at least one multiframe (multi-frame), each multiframe includes K frames, and each frame includes F bytes, where K and F are both positive integers.

In the embodiment of the present invention, the JESD204 data is re-segmented in units of 8 bytes to obtain multiple JESD204 frames with a specification of 64bit Block, that is to say, frame and mulftiframe are defined in the prior art, and JESD204 frames The amount defined by the invention; since the JESD204 data includes three parts: code-level synchronization, ILA sequence and service data, the JESD204 frame can be correspondingly divided into three frame types: code-level synchronization frame, ILA sequence frame and service data frame. Normally, the encoding terminal can determine the frame type of the target JESD204 frame through a local state machine.

Taking Figure 8 as an example, the 8 bytes described above can be called the 0th byte, the 1st byte, the 2nd byte, the 3rd byte, the 4th byte, and the 5 bytes, the 6th byte and the 7th byte, wherein, the 0th byte is the first byte, and the 7th byte is the last byte.

Step S702: The encoding terminal encodes the target JESD204 frame by 64B66B encoding technology to obtain a 66-bit transmission frame, the transmission frame consists of 8 bytes and 2 bits, and the 2 bits are the frame header of the transmission frame.

Specifically, the encoding terminal encodes JESD204 frames of different frame types in different ways.

When the target JESD204 frame belongs to the code-level synchronization frame, the frame header of the encoded transmission frame carries the first identifier, and the data carried by each byte of the 8 bytes of the transmission frame is D28.5. Optionally, the data corresponding relationship of the transmission frame obtained by coding the target JESD204 frame is shown in FIG. 9 .

When the target JESD204 frame belongs to the ILA sequence frame and the 0th byte of the target JESD204 frame is the control word R, the frame header of the encoded transmission frame carries the first identifier, and the 8 bytes of the transmission frame The preset data carried by the nth byte is D28.0, and the 7 bytes except the nth byte in the 8 bytes of the transmission frame correspond to the 8 bytes of the ILA sequence frame The data in the last 7 bytes in.

Optionally, the data corresponding relationship of the transmission frame obtained by coding the target JESD204 frame is shown in FIG. 10 .

In an optional solution, when the target JESD204 frame belongs to the service data frame and the data carried in the 8 bytes of the target JESD204 frame are all D28.5, the frame header of the encoded transmission frame carries the first Second, the data carried in the 8 bytes of the transmission frame are all D28.5.
