Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] In related technologies, when using the ILKN protocol for data transmission, multiple data transmission channels may be provided between two processing chips (ie, the processing chip on the sending side and the processing chip on the receiving side). For ease of understanding, the number of data transmission channels between two processing chips is 8 (that is, channel 0-channel 8) as an example for illustration. The bandwidth of each data transmission channel is 67bit.

Abstract

Embodiments of the present application provide a data processing method, device, and processing chip. The scheme is as follows: obtain the first data; shift the invalid data in the first data to the valid data to obtain the second data; cache the second data in the FIFO cache, and perform EOP position retrieval to obtain the first retrieval result; Splicing the first residual data, the preset buoy and the cached data output by the FIFO buffer to obtain the first splicing array; performing EOP position retrieval on the first residual data in the first splicing array to obtain the second retrieval result; according to the first For the search result and the second search result, the target data is output when the first concatenated array satisfies the preset output condition. Applying the technical solution provided by the embodiment of the present application ensures the matching between the data transmission bandwidth and the timing processing capability of the processing chip in the case of multi-data channel transmission, so as to realize the receiving design of the chip ILKN_LA and maintain the normal progress of data transmission.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data processing method, device and processing chip. Background technique [0002] Due to the high-speed data transmission requirements of network chips, the data transmission bandwidth requirements for data transmitted based on the inter-chip high-speed data transmission (Interlaken, ILKN) protocol are getting higher and higher. At present, in the face of the continuously 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), and if 8 data transmission channels are expanded to 16 data transmission channels, the data transmission bandwidth will be doubled, that is, data The transmission bandwidth increases by (16-8)*67bit.
