Inter-board multicast optical interconnection network constructing method based on development boards

Abstract

The invention provides an inter-board multicast optical interconnection network constructing method based on development boards. The method includes: constructing an inter-board multicast optical interconnection network, and inputting network load parameters and transmitting the same to a flow control module; setting data transmitting status, and setting development board address information and transmitting the same to a data packaging module; calculating and reading to obtain data flow to be transmitted, adding other data information to obtain data packets, and transmitting the data packets to a data transmitting module; sequentially encoding, parallel-serial converting, electro-optical converting, decoding, serial-parallel converting, and transmitting to a data receiving module; performing error code and delay calculation, parsing number residual packets in transmission, and feeding the number back to the flow control module. By the multicast optical interconnection network based on the development boards, network performance in terms of bandwidth, throughput rate, delay and the like is increased. In addition, the multicast optical interconnection network is high in universality and low in cost.

Description

technical field [0001] The invention relates to an optical interconnection network architecture method, in particular to an inter-board multicast optical interconnection network architecture method based on a development board. Background technique [0002] With the development of large-scale integrated circuits, traditional electrical interconnection methods gradually show shortcomings such as low bandwidth, high delay, high energy consumption, and poor anti-interference, which is the so-called "electronic bottleneck". Due to its high bandwidth, low delay, low energy consumption, and low crosstalk, optical interconnection is favored by future communication systems. At present, many research institutions at home and abroad have begun to pay attention to the architecture of optical interconnection networks, but most of these works remain at the level of theory and simulation, and there is still a lack of specific solutions for the physical realization of network architecture....

At present, many research institutions at home and abroad have begun to pay attention to the architecture of optical interconnection networks, but most of these works remain at the level of theory and simulation, and there is still a lack of specific solutions for the physical realization of network architecture.

First of all, because light cannot be buffered, it will be more difficult to process optical signals; secondly, the cooperative work between chips after multi-chip interconnection requires real-time communication, and the sending and receiving of a large amount of data brings great challenges to communication; finally, due to The cost of large-scale ASIC verification is extremely high
