Problems solved by technology

[0002] In the time slot multiplexing communication protocol, the data packets are scattered in their respective time slots. When the data packets need to be reassembled, the traditional method is to cache each time slot separately. Although it is easier to implement separate buffering, it will Causes a waste of cache resources, because cache resources will also be occupied when there is no data packet in a certain time slot

example

[0051] For an 8-bit wide communication input data, each input data is 8 bits (that is, 1 byte). For a communication protocol with multi-slot multiplexing, for example, it may be assumed that there is a data packet in the first time slot, and the processing method of any other time slot is exactly the same as that of the first time slot, so only one first time slot is given as an example. Can. It may be assumed that there is a data packet with the shortest length of 3 bytes in the first time slot, and the processing method for other data packets with any longer length is exactly the same as the processing method for this data packet. Assume that the data packet is "9B6A5D" from the beginning to the end (using hexadecimal, high-order representation, the following data and addresses use this representation by default.).

[0052] The time slot buffer module first receives the beginning segment of the data packet in the input data, ie "9B". The address dynamic cache module alloca...

Abstract

The invention discloses a method for realizing time slot data packet recombination by time division multiplexing cache. According to the method, time division multiplexing is carried out on cache resources, namely for the same data cache, a plurality of data packets with different time slots are stored at different time; data packets in different time slots of input original time slot multiplexingcommunication protocol data are stored in the same data cache, and when the data packets are recombined and output, the data cache is read according to the linked list addresses, and the continuouslyoutput of the data packets in a certain time slot is realized; after the addresses of the data cache are manageddynamically to be written into a certain address of the data cache, the address is marked to occupied, and after the certain address of the data cache is read out, the address is marked to be released and to be an idle address, and the idle address of the data cache needs to be distributed before the address is written into the data cache. By the adoption of the scheme, recombination of the data packets in a time slot multiplexing communication protocol is achieved, the cache utilization rate is increased, cache resources are saved, and the recombination of data packets in more time slots is realized based on the limited cache resources.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for time-division multiplexing and buffering to realize the recombination of time-slot data packets, and in particular to the reorganization of data packets in the time-slot multiplexing communication protocol. Background technique [0002] In the time slot multiplexing communication protocol, the data packets are scattered in their respective time slots. When the data packets need to be reassembled, the traditional method is to cache each time slot separately. Although it is easier to implement separate buffering, it will It causes a waste of cache resources, because cache resources are also occupied when there is no data packet in a certain time slot. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned practical applications, and in particular provide a method for time-division multiplexing and ...
