    摘要: An integrity check method applied to an electronic device includes: fetching at least one portion of external data into a specific memory, where the external data is stored within the electronic device; during fetching the portion of the external data into the specific memory, checking whether the size of the fetched data in the specific memory reaches a predetermined value, where the predetermined value is less than the total size of the external data; and when the size of the fetched data in the specific memory reaches the predetermined value, enabling an integrity check of the fetched data.

    摘要: An optical disc drive includes a firmware memory, a buffer memory, and a system control chip. The system control chip includes a processor and a memory update controller. When the optical disc drive is under a normal mode, the memory update controller is in an idle state. The processor controls the optical disc drive to fetch an update firmware from an optical disc and store the update firmware into the buffer memory. When the optical disc drive is under a firmware update mode, the processor is in an idle state. The memory update controller fetches the update firmware from the buffer memory and stores the update firmware into the firmware memory without the processor executing an update routine code.

    摘要: A data transmitting end utilizes a clock signal to transmit at least a data signal to a data receiving end. An adjustable delay compensation circuit for compensating data transmission delay between the data transmitting end and the data receiving end includes an adjustable delay circuit, a clock gating circuit, and at least a target signal generating circuit. The adjustable delay circuit is used for delaying the clock signal by a programmable delay amount to generate a target delay signal. The clock gating circuit is used for allowing the clock signal to reach the adjustable delay circuit when receiving a data transmission enabling signal. The target signal generating circuit is used for receiving the data signal and for sampling the data signal according to the target delay signal.
