METHOD AND DEVICE FOR SECURE ACCESS CONTROL BASED ON ON-CHIP BUS PROTOCOL

摘要

A method for secure access control based on an on-chip bus (advanced eXtensible interface, AXI) protocol is disclosed and comprises dividing a bus address space into more than one area, then determining the security attributes of each area; and, determining whether the security type of an access request, sent by a primary device, to access a target area matches the security attributes of said target area; if a match, sending said access request to a target secondary device. A device for secure access control based on the AXI protocol is also disclosed.
