Embodiment Construction

[0020] Please see figure 1 , which shows a schematic diagram of the application environment of the writing control device 10 of this embodiment. The write control device 10 is applied in an electronic device 100 . The electronic device 100 includes a write control device 10 , a central processing unit (CPU) 20 , and a memory 30 . The CPU 20 sends data to be written into the memory 30 to the memory 30 . After receiving the data, the memory 30 performs a write operation on the data, and sends a write completion instruction to the central processing unit 20 when the data is written. The write control device 10 is software, hardware, or firmware combining software and hardware installed on the electronic device 100 . The writing control device 10 is used for controlling the writing operation of the central processing unit 20 to the memory 30 .

[0021] Please see figure 2 , which is a functional block diagram of the write control device 10 . The write control device 10 incl...

Abstract

An electronic device includes a storage and a processor. When the processor performs a data transmission process performed by the processor to transmit data to the storage, a time period duration of writing data into the storage is timed. An Acknowledge (ACK) signal indicating the data is successfully written into the storage is detected. If the ACK signal is not detected and the time period duration exceeds a predetermined time period, the processor restarts the data transmission process to re-transmit the data to the storage, to avoid system crash.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a write control method and control device for electronic equipment and its memory. Background technique [0002] In existing electronic equipment, the process of writing data to the memory is as follows: the central processing unit (CPU) sends a piece of data to the memory; the memory sends an ACK signal to the central processing unit after writing the data; after the central processing unit receives the ACK signal, Start processing the next task or sending the next data. If the memory makes an error in the process of writing data, for example, the memory is abnormally interrupted when writing data, so the memory cannot send an ACK signal to the central processing unit, which will cause the central processing unit to be unable to perform the next task or send the next data, thereby causing the The electronic device crashes or cannot write data.
