A data-processing device is provided. The data-processing device includes: a flash memory, a computation unit, and a flash-memory controller. The flash-memory controller is electrically connected to the computation unit, and configured to control access to the flash memory. The flash-memory controller allocates a first execute-only memory (XOM) setting and a second XOM setting in a first memory bank and a second memory bank of the flash memory, respectively. The flash-memory controller allocates one or more XOM spaces in the flash memory according to the first XOM setting or the second XOM setting.

Data-processing device and data-protection method thereof

An audio synchronization processing method is provided. The method includes the following steps: receiving an input request signal; in response to receiving the input request signal, starting performing a counting operation according to a basic clock signal; outputting an output request signal according to a sampling-clock signal; in response to outputting the output request signal, stopping performing the counting operation to obtain a counting value; determining whether synchronization has been achieved based on the counting value; and in response to determining that the synchronization has not been reached, adjusting a frequency of the sampling-clock signal according to the counting value.

Audio synchronization processing circuit and method thereof

A pulse width modulation signal generation circuit and a pulse width modulation signal generation method are provided. A clock generator is configured for generating a clock signal including a plurality of pulses. The counting unit is coupled to the clock generator, and configured for storing a period parameter and outputting a counting value by counting the pulses of the clock signal based on the period parameter and a bidirectional counting mode. The comparing unit is coupled to the counting unit and is configured for comparing the counting value and a comparing threshold to output a level control signal. The signal generating unit is coupled to the comparing unit and configured for generating a pulse width modulation signal according to the level control signal. When the period parameter is odd, the counting value outputted by the counting unit is equal to a middle value in the two continuous clock cycles.
