  • Data access control method and apparatus
    Patent number: 9883157
    Abstract: One embodiment of the present invention discloses a data access method comprising: (a) receiving a plurality of data units consisting of filtered data units and un-filtered data units; (b) filtering the filtered data units; (c) storing the un-filtered data units; (d) recovering the timings of the un-filtered data units stored in the step (c) according to the received timings of the data units received in the step (a); (e) inserting replacement data units to replace the filtered data units, wherein each of the replacement data units has the same timing as each of the filtered data units; and (f) outputting the un-filtered data units and the replacement data units according to the timings of the un-filtered data units and the timing of the replacement data unit.

  • Data sampling and data encryption/decryption method and electronic device utilizing the methods
    Patent number: 9210471
    Abstract: In one embodiment of the present invention, a signal sampling method is provided. It comprises: (a) sampling an input signal with respect to a sampling clock signal; (b) calculating a maximum transition timing and a minimum transition timing of the input signal according to a relation between the sampling in step (a) and a reference timing clock; (c) defining a voltage level transition interval according to the maximum transition timing and the minimum transition timing; and (d) determining phase of the sampling clock signal or phase of the input signal according to the voltage level transition interval.
