AI Technical Summary

Technical Problem

In heterogeneous multi-core system-on-a-chip, data exchange between on-chip functional modules relies on shared memory synchronization, which is delayed and inefficient. Existing technologies require frequent CPU intervention, leading to increased latency and system overhead.

Method used

A tag management unit is deployed within the system-on-a-chip (SoC) to monitor writes to the hardware mailbox, obtain memory synchronization information, and directly update access control tags, thereby achieving memory synchronization between on-chip functional modules and avoiding CPU involvement.

Benefits of technology

It improves memory synchronization efficiency, reduces latency and system overhead caused by CPU scheduling and interrupt handling, and enhances the efficiency and determinism of multi-module collaborative processing.
