AI Technical Summary

Technical Problem

The existing AHB bus interconnect structure suffers from problems such as wasted bus bandwidth, increased access latency, disordered data transmission sequence, and insufficient robustness in slave ready signal processing when multiple masters concurrently access slaves or switch masters, causing the system to malfunction.

Method used

A high-performance arbitration device based on the AHB bus was designed. It adopts the ARB arbitration module and Hready feedback network architecture to realize dynamic arbitration collaborative control, ensure continuous and uninterrupted command issuance, introduce fine-grained master-slave switching control logic, and enhance the system's anomaly handling capability through an arbitration failure handling mechanism.

Benefits of technology

It improves the utilization rate and data transmission efficiency of the bus in multi-master and multi-slave competition scenarios, maximizes bus bandwidth utilization, reduces access latency, avoids data loss or corruption, and enhances the system's ability to handle abnormal situations.

Abstract

An AHB bus-based high-performance arbitration device, the arbitration device comprising: an ARB arbitration module, the ARB arbitration module being arranged between a plurality of slaves and a plurality of masters, receiving instructions and data transmitted by the masters and issuing to corresponding slaves, and being capable of realizing non-interval continuous issuing of commands when different slaves are accessed by the same master or the same slave is accessed by different masters, thereby ensuring correct and efficient transmission of data; the ARB arbitration module is arranged correspondingly and in consistent number with the slaves; and an Hready feedback network architecture, the Hready feedback network architecture being used to build a feedback network between the masters, the slaves and the ARB arbitration module, and ensuring correct and efficient access of the multiple masters and the multiple slaves.
