    摘要: A jitter measuring method and device, which is capable of measuring jitters in serial digital signal without high-frequency reference clock. The jitter measuring device comprises a rough length measuring unit for measuring rough length for each pulse of the serial digital signal according to a reference clock, and a phase error measuring unit for measuring the phase errors between the edges of the reference clock and the serial digital signal by multi-phase clocks, which are generated by a multi-phase generator according to the reference clock. The jitter measuring device computes the precise length according to the rough length and the phase error, and measures the jitters from the precise length by filters.

    摘要: A programmable system for storage of one-time programmable information comprises an interface translator and a one-time programmable device. The interface translator receives and translates a command code to program code comprising a sequence of write instructions and a designated data block. The one-time programmable device is coupled to the interface translator, programmed by the write instructions to store the designated data block. The one-time programmable device can only be programmed once, such that the designated data block being stored is fully protected.

    摘要: A modulation system includes an encoder for transferring data words to tentative code words. A DSV control bit generator determines the value of a DSV control bit according to the data words or the tentative code words to optimize the cumulative DSVs corresponding tentative code words, wherein the DSV control bit generator determines the value of a current DSV control bit when at least a subsequent DSV control bit is detected. A final code word generator generates final code words according to the determined DSV control bit and the tentative code words.

    摘要: An embedded system and an operating method thereof are disclosed. The embedded system comprises a micro-processor and a co-processor. The co-processor can only process non-interruptible instructions. The micro-processor is powered by an operating system to control the embedded system. When a task requires execution, the micro-processor appoints the co-processor to execute at least one batch command block. The batch command block is compiled with a sequence of non-interruptible instructions. When the task is complete, the co-processor outputs a response signal to the micro-processor.

    摘要: Methods and systems for dynamically updating velocity dependent parameters during optical disc accessing are provided. A velocity estimator estimates a current velocity of a rotating disc. A storage unit stores a plurality set of parameters, each set corresponds to a preset velocity, and a register stores velocity dependent parameters that are currently used for data recording. A batch controller retrieves a set of parameters from the storage unit according to the current velocity estimated by the velocity estimator, and updates the velocity dependent parameter stored in the register using the parameters retrieved from the storage unit.
