Problems solved by technology

[0014] Performing P:1 backup will result in the delay required by the crossover being P times larger than the first solution, which is not suitable for occasions that require fast service scheduling. In addition, the implementation of this solution is relatively complicated, and the implementation structure is not convenient for easy expansion at will. Rapid Development Model for Today's ASICs

Embodiment 1

[0049] The implementation method for space-division and time-division cross-connection provided by Embodiment 1 of the present invention is described by taking parallel scheduling of multi-bit services as an example. Specifically, a non-blocking crossover that implements 128*128 channels, each channel has 16 time slots, and is processed in parallel with 8 bits is taken as an example.

[0050] First perform 128×1 crossover, and then instantiate 128 copies, specifically:

[0051] First design a 128-choice multiplexer (MUX), and instantiate 8 copies of it to generate a multiplexer with a time slot, a total of 16 time slots, and need to instantiate 16 times again, each time slot gap corresponds to one.

[0052] Redesign the configuration storage unit, 16 time slots, and the scheduling information stored in each time slot includes the input channel and the input time slot from which the output time slot comes. For the first embodiment, 128 channels need 7bit information coding, an...

Embodiment 2

[0057] The implementation method for space division and time division cross-connection provided by Embodiment 2 of the present invention is described by taking the independent scheduling of single-bit services as an example. Specifically, an implementation of 128×128 channels, each with 16 time slots, for which input 8-bit parallel data requires non-blocking interleaving by bit is taken as an example.

[0058] First perform 128×1 crossover, including the following three parts:

[0059] First design a multiplexer (MUX) with 128 selections, and instantiate 8 copies of it to generate a multiplexer with a time slot. 16 time slots, 16 more instantiations are required, one for each time slot. The selection terminals of the 8 multiplexers corresponding to each time slot no longer come from the same control information, but from 8 different control signals.

[0060] Redesign the configuration storage unit, 16 time slots, and the scheduling information stored in each time slot includ...

Abstract

The present invention discloses a method for crossly realizing space division and time division and a device thereof. The invention relates to the communication field and settles the problems of resource waste, high cost and high power consumption in realizing crossing of space division and time division. The settling solution comprises the following steps: extracting the data of one channel to be processed in the input multi-channel code; inserting the data to be processed into a preset channel; selecting the data which requires time slot scheduling from the channel, and inserting the data which requires time slot scheduling into a data storing unit. The method and the device of the invention are used for crossing space division and time division.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for realizing space division and time division crossover. Background technique [0002] Space-division and time-division cross-connect applications have been used for business scheduling in networks with fixed frame structure and byte interleaving for a long time. However, with the continuous expansion of network scale, the cross-connect capacity increases exponentially. [0003] The so-called fixed frame structure means that a certain network frame structure is fixed to n rows X m columns, and its frame structure and frame length are the same for each frame, and will not change with time. [0004] The so-called byte interleaving means that in order to improve the bandwidth of a certain physical channel, the information it transmits is divided into x time slices in time, and each time slice transmits a set of information. [0005] At present, the main method for ...
