Embodiment Construction

[0026] The core of the present invention is to divide the input services to be crossed into appropriate groups according to the size, and set a certain number and capacity of data memory and delay memory for each group, and by time-sharing the data memory in each group The operation obtains the data after each crossover in sequence, and temporarily stores the obtained crossover data in the delay memory. When the last way reads the crossover data from the data memory, it temporarily stores the first few channels in the delay memory The data after the crossover obtained from the data storage is output synchronously, thereby realizing the full T crossover of the services in the group, and controlling these groups to output their respective full crossover service data synchronously according to the same working mode, thereby completing all the service data to be crossed The full T cross.

[0027] In order to enable those skilled in the art to better understand the solution of the pres...

Abstract

This invention discloses a method for increasing the efficiency of data storages in total interleave including: designing the service to be interleaved N channels, the sum of the least particle service participating the interleave in each channel is M, designing L channels in N for being interleaved to be one set to design N / L sets data storages and delay storages, controlling the data and delay storages in each set to finish the total interleave of N channel input and l channel output, synchronously controlling said N / L set delay storage to finish the total T interleave of N channel output.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for improving the use efficiency of data storage. Background technique [0002] With the development of communication technology, the amount of information carried in SDH (Synchronous Digital Hierarchy) / SONET (Synchronous Optical Network) networks is increasing. In this way, the most important network element digital cross-connect equipment in SDH / SONET networks is required. (DXC) has greater exchange capacity. The core of DXC is a cross-connect matrix, which realizes the cross-connection of VC (virtual container). Usually the function of the cross-connect matrix is ​​completed by the cross chip. For the realization of high-capacity cross-chips, no matter from the complexity of the chip implementation or the price of the chip, the size of the RAM used on-chip is a very important factor. As the cross-chip cross-capacity increases, This factor has become increasi...
