DATA PROCESSING DEVICE AND DATA PROCESSING METHOD

摘要

Embodiments of the present invention provide a data processing device and a data processing method. In the data processing device and the data processing method provided by the embodiments of the present invention, first data in a memory is written into a first non-volatile storage unit in a log file form, and a log file of the first data written into the first non-volatile storage unit is written into a second non-volatile storage unit. Because a data write speed of the first non-volatile storage unit is higher than a data write speed of the second non-volatile storage unit, fast backup of the data in the memory can be achieved, and when the data in the memory is lost in an abnormal situation, security of the data in the memory can be ensured.

主权项

1. A data processing device, comprising:
a control unit; a memory coupled to the control unit; a first non-volatile storage unit coupled to the control unit; and a second non-volatile storage unit coupled to the first non-volatile storage unit, wherein a data write speed of the first non-volatile storage unit is higher than a data write speed of the second non-volatile storage unit, wherein the control unit is configured to write first data into the memory, and write log file of the first data into the first non-volatile storage unit, and wherein the log file of the first data records data changes of the first data, and write, into the second non-volatile storage unit, the log file of the first data written into the first non-volatile storage unit.
