A computing device is provided that includes a computing unit, which has a working memory and a processing unit, and a boot memory having control instructions for operating the computing device. The control instructions are stored in boot memory and are to be transferred to the computing unit at start-up of the computing device. A boot control unit is connected to the computing unit by at least a first and a second interface and connected to the boot memory by a third interface. The boot control unit is configured to transfer a first part of the control instructions from the boot memory via the first interface to the computing unit and to transfer a second part of the control instructions from the boot memory via the second interface to the computing unit.

Booting a computer system at start-up by transferring a first part of instructions using a second bus and transferring a second part of instructions using a first bus where the second bus is configured to transfer instructions at a faster rate than the first bus

An electric motor system having a rotor with a plurality of permanent magnets, and a stator having a winding through which current is flowing for driving the rotor. A control unit controls the current flowing through the winding. The control unit employs a first filter and a second filter, each filter is connected to the winding and has outputs coupled to a comparator. The comparator compares the signal output of the first filter to the signal output of the second filter. The control unit controls the current flowing through the winding depending on the result of the comparison of the two filtered signals.
