    摘要: In an apparatus and method for converting the frame rate of an image signal in a display system without an external memory, the display system and method are capable of down converting the frame rate of an image signal using a frame rate conversion unit without an external memory. The system and method can be used even in the case where the frequencies of input and output synchronization signals are locked to the same frame rate. The frame rate conversion unit disable-masks portions of the frames of a data enable signal or a vertical synchronization signal, thus canceling the portions of the frames, and outputs the masked data enable signal or the masked vertical synchronization signal to an LCD driving circuit unit, thereby down converting the frame rate of the image signal.

    摘要: A control circuit used to transfer data to a programmable memory in an electronic device can be separate from a general operation processor circuit that controls general operations of the electronic device. The controller circuit may allow a transfer of data to the programmable memory without the use of Random Access Memory (RAM) or a Read Only Memory (ROM) that is under the control of the general operation processor circuit. The general operation processor circuit can be disabled by the controller circuit while data is transferred (i.e. programmed to) programmable memory.
