AI Technical Summary

Technical Problem

In the existing Crossbar architecture, the MUX structure between the input and output channels is large and complex, consuming a lot of logical resources.

Method used

By reducing the MUX input bit width between the input and output channels, only channels with a data transmission probability higher than a preset threshold are connected, while redundant channels are discarded, and a multiplexer with a smaller bit width is used.

Benefits of technology

This reduces the consumption of logic resources and enables a Crossbar data transmission architecture that is small in size, low in power consumption, and fast in speed.

Abstract

一种Crossbar数据传输架构，包括：多个输入通道、多个输出通道；每个输出通道与特定关系的输入通道连通；特定关系是根据数据从输入通道传输的概率来确定的；数据从特定关系的输入通道传输至连通的输出通道的概率大于预设阈值；其中，当目标数据输入所述Crossbar数据传输架构时，目标数据从特定关系的输入通道输入，从连通的输出通道输出；在特定关系的输入通道与连通的输出通道之间，Crossbar数据传输架构选择了较少位宽的多路选通器。本申请的Crossbar数据传输架构，舍弃了传输数据概率低于或等于预设阈值的通道，减少了对应的资源占用。使得本申请的Crossbar数据传输架构，相比于传统的Crossbar架构，除去冗余部分，保留常用部分，具有面积小，功耗低，速度快的优点。
