1. an electronic system (100,300), comprises:

  • Multiple equipment (110,120), be configured to via common bus structure at transmission signal each other, wherein said multiple equipment is included in the initiator (110) of distributing data move instruction in described common bus structure and the target side (120) of described data movement instruction addressing;

    Access control matrix (160), the authority that each initiator (110) accesses each target side (120) via described common bus structure is mapped, wherein said access control matrix (160) is programmable, thusI () revises the access rights of described initiator (110) or described target side (120), or(ii) for the initiator (110) added or the target side (120) of interpolation are created to the access rights of described multiple equipment;

    AndAccess controller (140,310), is operationally coupled to described multiple equipment (110,120) and described access control matrix (160), and is configured to;

    -receive the data transmission requests mailing to described target side (120) from described initiator (110);

    And-according to the access rights of the described initiator (110) specified in described access control matrix (160) and described target side (120) and the input port distributing to described initiator (110), determine whether to authorize this data transmission requests.
