  • Patent number: 9141566
    Abstract: A method of accessing an on-chip read only memory (ROM) includes dividing a frequency of a system clock by a specific divisor, in order to generate a ROM clock; combining a specific number of adjacent addresses into a combined address, wherein the specific number is determined according to the specific divisor; inserting a first stall signal into a real output data, wherein a length of the first stall signal is determined in order to meet a timing requirement for accessing the on-chip ROM; generating an output data of the on-chip ROM according to the combined address, wherein a width of the output data is extended by a specific multiple which is determined according to the specific number; and generating a first delay corresponding to the length of the first stall signal in the address.

  • Patent number: 8707135
    Abstract: A method of dynamic data storage for error correction in a memory device is disclosed. Data for storage is received, the received data is encoded and error correction code (ECC) is generated. The encoded data is stored in the memory device that includes a plurality of pages each having a plurality of data partitions. More corrected errors a marked page has, a smaller portion with a space of at least one datum of each of the corresponding data partitions associated with the marked page is allocated to store the encoded data, while a size of the ECC is fixed, thereby increasing capability of correcting errors in the marked page.

  • Publication number: 20130113923
    Abstract: A blind spot detection alert system. The system comprises two image capturing modules, a processing module, a first display module and a second display module. The two image capturing modules capture a right image and a left image respectively. The first display module is disposed on the right of the second display module. The processing module receives the right image and the left image to analyze a car moving direction. When the processing module determines the car moving direction is a right direction, the first display module displays the right image. When the processing module determines the car moving direction is a left direction, the second display module displays the left image. The processing module calculates a distance to a coming car, a moving direction of the coming car and a speed of the coming car according to the image to get an alert message.

  • Publication number: 20130100287
    Abstract: A blind spot detection system and method thereof applicable to a transportation vehicle. The blind spot detection system comprises a plurality of detection modules, a processing module and a display module. When the transportation vehicle moves at a speed less than a predetermined speed or at a stop moving state, each detection module is used to detect a plurality of blind spot images around the transportation vehicle. The processing module is connected to each detection module and used to receive the plurality of blind spot images and execute an image processing for detecting and identifying a moving object in the plurality of blind spot images, and to generate a mark pattern corresponding to the moving object. The display module is connected to the processing module and used to display the plurality of blind spot images and the mark pattern in a blind spot display mode.

  • Patent number: 8429497
    Abstract: A method of dynamic data storage for error correction in a memory device is disclosed. Data for storage is received, and the received data is then encoded and associated error correction code (ECC) is generated. The encoded data is stored in a portion of a data partition of the memory device, wherein percentage of the stored data in the data partition is determined according to an amount of corrected errors associated with the data partition or is predetermined.

  • Patent number: 8332607
    Abstract: A non-volatile memory storage device has a non-volatile memory, e.g., a flash memory, and a controller coupled to the non-volatile memory. The controller comprises a plurality of control circuits and an arbitration circuit. Each control circuit is configured to generate a request to update the chip-enable (CE) signals for non-volatile memory, and the arbitration circuit is configured to determine when the requests are acknowledged. The arbitration circuit generates acknowledge signals to the control circuits when all of the requests of the control circuits have been received by the arbitration circuit. The CE signals for non-volatile memory are updated when requests are acknowledged.
