An electronic device has a management data input/output (MDIO) bus, a control unit, and an MDIO master. The control circuit receives a host command from a host device, and outputs a plurality of MDIO commands in response to the host command. The MDIO master receives the MDIO commands from the control circuit, and transmits the MDIO commands to the MDIO bus.

A loading control method and system for a storage device are disclosed. The method comprises: judging whether a storage controller is valid through a first bus, and judging whether a storage controller is valid through a first bus, and acquiring a key of the storage controller if a positive judgement is made; judging whether the key is valid, commanding the storage controller to turn on a power supply of a storage device if a positive judgement is made; and loading the storage device through a second bus. According to the method, storage devices based on windows and android are allowed to be loaded after the storage device verification is successful, and by means of the method, data security of a user can be effectively protected, which provides reliable and effective protection for future private cloud service data.

The present disclosure relates to a function connection unit for connecting functional modules. The functional connection unit includes a plurality of functional module terminals configured to connect to the functional modules and to communicate according to a first communication protocol, and a parameter memory that includes parameter data for device specific parameterization of at least one functional module. The parameter memory is configured to connect to a functional module terminal of the plurality of functional module terminals. The function connection unit is configured to read the parameter data from the parameter memory. The function connection unit is also configured to parameterize at least one functional module in a device-specific fashion based at least in part on the read parameter data.

A method of controlling direct memory access of a peripheral memory of a peripheral by a master is described. The method includes checking whether there is a pending request from the peripheral for a direct memory access service, establishing whether an access condition is satisfied in dependence on at least whether there is a pending request, and, if the access condition is satisfied, granting access to the master. Also, an associated device and an associated computer program product are described.

The present invention realizes a functional safety of a multiprocessor system without tightly coupling processor elements. When causing a plurality of processor elements to execute the same data processing and realizing a functional safety of the processor element, there is adopted a bus interface unit that performs control of performing safety measure processing when the non-coincidence of access requests issued from the processor elements has been fixed, and of starting access processing responding the access request when these access requests coincide with one another.
