Description

Coding method, related device and system

Technical field

The embodiments of the present invention relate to the field of computer technologies, and in particular, to an encoding method, related device, and system.

Background technique

Solid State Semiconductor Industry Reliability Standard JESD204 series protocol is a serial interface standard based on serializer/deserializer (English: SERializer/DESerializer, SERDES for short). It is used to define application specific integrated circuit (English: Application Specific Integrated Circuit). :ASIC)/Field Programmable Gate Array (English: Field-Programmable Gate Array, FPGA) and Digital to Analog Converter (English: Digital to Analog Converter): Analog to Digital Converter (English: Analog to digital The interface between converter, referred to as: ADC), the topology defined by JESD204B protocol is shown in Figure 1. Downstream direction: The IF data of the ASIC/FPGA is transmitted to the DAC through the JESD204B interface, and then sent out from the RF air interface through the mixer (English: Mixer) and power amplifier (English: Power Amplifier, PA). Upstream direction: The data received from the RF air interface is amplified by a low noise amplifier (English: Low Noise Amplifier, LNA for short), and then frequency-converted to the intermediate frequency point 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 contains K frames. JESD204B data consists of three levels of data: CODE SYNC, Initial Lane Alignment (ILA) sequence and business data. The structure of these three data is shown in Figure 2.

Code level synchronization (CODE SYNC) consists of a continuous control word K (value K28.5). The second multiframe of the ILA sequence is in turn composed of the control word R (first byte), the control word Q, the control byte, the data and the control word A (the last byte); the other multiframes of the ILA sequence are in turn controlled by the control word R ( 1 byte), data and control word A (last byte). Among them, control word A (value K28.3) is used for multi-lane alignment, control word F (value is K28.7) for frame alignment (described after control word F), control word K (value is K28.5) for code level synchronization, control word R (value K28.0) is used to indicate the start of multiple frames in the ILA sequence, control word

Q (value K28.4) is used to indicate the start of the control word in the ILA sequence.

In order to improve the transmission characteristics of the JESD204B data on the link, it is necessary to insert the control word A or the control word F at the end of the data frame of the service data. Currently, the data frame can be encoded by the 8B10B coding technology to generate a specific pattern to distinguish Control word A, control word F and normal data. As shown in FIG. 3, the 8B10B encoding technique is to decompose a group of consecutive 8-bit data into two sets of data, one set of 3-bit data, and one set of 5-bit data, which are encoded into 1 set of 4 bits respectively. Data and a set of 6-bit data, the two sets of data constitute a set of 10 bits of data. The insertion of the control word F or the control word A at the end of the data frame includes two cases. The following describes the data frame shown in FIG. 4 as an example.

Unscrambled: As shown in Figure 5, if the last byte of the current frame (not at the end of the multiframe) is the same as the last byte of the previous frame, replace the last frame of the current frame with the control word F=K28.7. One byte. If a replacement has occurred in the previous frame, this time it will not be replaced. 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, replace the last byte of the current frame with the control word A=K28.3.

Scrambling situation: As shown in Figure 6, if the last byte of the current frame (not the last frame of the multiframe) is equal to 0xFC (ie D28.7), replace the last frame of the current frame with the control word F=K28.7 One byte. If the last byte of the multiframe is equal to 0x7C (ie D28.3), replace the last byte of the current frame with the control word A=K28.3.

A disadvantage of the prior art is that the 8B10B technology encodes an efficiency of 0.8, which requires a higher SERDES rate and SERDES logarithm.

detailed description

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to FIG. 7, FIG. 7 is a schematic flowchart diagram of an encoding method according to an embodiment of the present invention, where the method includes but is not limited to the following steps.

Step S701: The encoding terminal determines the frame type of the target JESD 204 frame in the JESD 204 data to be transmitted.

Specifically, the JESD204 data specifically refers to data based on the JESD204 series protocol, for example, currently using the more mature JESD204B protocol, and the JESD204C protocol that may be evolved in the future. Taking the JESD204B protocol as an example, the JESD204 data to be transmitted is composed of at least one multiframe, each multiframe includes K frames, and each frame contains F bytes, where K and F are positive integers.

In the embodiment of the present invention, the JESD204 data is re-segmented in units of 8 bytes to obtain a plurality of JESD204 frames of 64-bit block size, that is, the frame and the mulftiframe are defined in the prior art, and the JESD 204 frame-based The amount defined by the invention; since the JESD 204 data includes three parts of code level synchronization, ILA sequence, and service data, the JESD 204 frame can be correspondingly divided into three frame types: a code level synchronization frame, an ILA sequence frame, and a service data frame. Normally, the encoding terminal can determine the frame type of the target JESD 204 frame through the local state machine.

Taking FIG. 8 as an example, the eight bytes described above may be sequentially referred to as the 0th byte, the 1st byte, the 2nd byte, the 3rd byte, the 4th byte, and the 5 bytes, 6th byte, and 7th byte, where the 0th byte is the first byte and the 7th byte is the last byte.
