Abstract

The embodiment of the invention provides a data processing method and device and a processing chip. The method comprises the steps of obtaining first data; shifting invalid data in the first data to valid data to obtain second data; caching the second data into an FIFO cache, and performing EOP position retrieval to obtain a first retrieval result; splicing the first residual data, a preset buoy and cached data output by the FIFO cache to obtain a first spliced array; performing EOP position retrieval on the first residual data in the first splicing array to obtain a second retrieval result; and according to the first retrieval result and the second retrieval result, outputting the target data when the first splicing array meets a preset output condition. By applying the method provided by the embodiment of the invention, the matching between the data transmission bandwidth and the time sequence processing capability of the processing chip is ensured under the condition of multi-data channel transmission, so that the receiving design of the chip ILKNLA is realized, and the normal operation of data transmission is maintained.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular, to a data processing method, device and processing chip. Background technique

[0002] Due to the requirements of high-speed data transmission of network chips, the data transmission bandwidth requirements for data transmitted based on the high-speed data transmission between chips (Interlaken, ILKN) protocol are getting higher and higher. At present, in the face of the increasing demand for data transmission bandwidth, the data transmission bandwidth is increased by expanding the number of data transmission channels. For example, the transmission bandwidth of each data channel (that is, the width of each data transmission channel) is 67 bits (bit). If 8 data transmission channels are expanded to 16 data transmission channels, the data transmission bandwidth will be doubled. The transmission bandwidth is increased by (16-8)*67bit.
