摘要
Abstract
This paper presents a system-level memory protection unit based on bus matrix.The unit supports supervisor and user modes.It can not only be flexibly configured according to the number of bus matrix masters,but also monitor all masters'activities in the sys-tem in real time,effectively preventing unauthorized masters from accessing specific memory areas.It addresses the functional safety problem of task interference caused by a single master-based memory access protection mechanism.In addition,the design supports the implementation of different protection strategies for the same memory region.This capability can protect the private data and shared da-ta of each core,and solves the data consistency problem in multi-core system architecture with minimum hardware cost.关键词
