Abstract
A data processing method and apparatus are provided. The data processing apparatus includes a converter module and a control module. The converter module receives a clock signal through a pin, and decides a bit value of the first data according to a length of a corresponding period of the clock signal. The control module determines whether to perform a bit writing operation for writing the bit value into a memory according to the clock signal and the first data.
Claims26
A data processing method, comprising:
- receiving a clock signal through a pin;
- performing a reversible logic operation on original data to generate first data, wherein a number of bits having a first logic value requiring a bit writing operation in the first data is less than a number of bits having the first logic value requiring the bit writing operation in the original data, and a number of bits of the first data is equal to a number of bits of the original data;
- determining a bit value of the first data according to a time length of a corresponding period of the clock signal;
- and
- determining whether to perform the bit writing operation into a memory according to the clock signal and the first data, wherein the bit writing operation is performed on the bit value when the bit value of the first data is determined to be the first logic value, and the bit writing operation is not performed on the bit value when the bit value of the first data is determined to be a second logic value.
