Abstract: A controlling system for an electric bicycle is connected to a CAN bus of the electric bicycle and a controlling end, and configured to control a plurality of electric elements which are signally connected to the CAN bus. A dongle module includes a first connecting port, a dongle and a second connecting port. The controlling end is configured to transmit a USB signal to the first connecting port. One end of the dongle is coupled to the first connecting port, and the dongle is configured to convert the USB signal into a CAN signal. The second connecting port is coupled to another end of the dongle. A console includes a console port. The console port is detachably connected to the second connecting port and coupled to the CAN bus. The CAN signal is transmitted to the CAN bus via the second connecting port and the console port.

Abstract: A method for loading image data required by a motion estimation into a storage medium, the method includes: determining if an overlap portion between a current search range and a previous search range exists; and if the overlap portion exists; keeping image data corresponding to the overlap portion stored in the storage medium; identifying a non-overlap portion between the current search range and the previous search range; dividing the non-overlap portion into at least one sub-block; and loading image data corresponding to each sub-block into the storage medium for utilization by the motion estimation.

Abstract: A multimedia decoding apparatus and method thereof can accelerate decoding speed. The multimedia decoding apparatus is adapted for decoding a multimedia packet that includes a header portion and a data portion. The multimedia decoding apparatus includes a header parsing module, a storage unit, and a data processing module. The header parsing module receives the multimedia packet and parses the header portion of the multimedia packet to output at least one parameter. The storage unit is coupled to the header parsing module for storing the parameter and the data portion of the multimedia packet. The data processing module is coupled to the storage unit for processing the data portion of the multimedia packet according to the parameter. When the data processing module processes the data portion of the multimedia packet, the header parsing module parses the header portion of another multimedia packet simultaneously.

Abstract: The present invention discloses an apparatus for sharing access by two modules includes at least a storage unit, a first module, and a second module. The second module is coupled to the first module and the storage unit, for accessing the storage unit according to a transmission protocol. The first module accesses the storage unit through the second module according to the transmission protocol. The present invention allows the first module to share access to the storage unit with the second module and thus the first module no longer needs to connect to another storage unit.
