Problems solved by technology
However, the speed of disks (HDD or SSD) on the market often cannot support such high-frequency reading and writing; moreover, disks (HDD or SSD) generally read and write in units of files, and a file occupies at least one sector, resulting in Even if only one byte is modified, a complete sector must be written, which is inefficient; in addition, high-frequency reading and writing of the disk will quickly consume the service life of the disk
[0005] In addition, if the power is cut off during the data writing process, some data may have been written and some data may not be written, and the correctness of the data will not be guaranteed; The time is longer, resulting in a relatively high probability of the above situation occurring

The invention discloses a nonvolatile data storage structure and a nonvolatile data storage method. The nonvolatile data storage structure comprises a nonvolatile storage unit NVRAM, an NVRAM mirror image storage unit, an NVRAM read-write manager and an NVRAM and mirror image synchronization unit, wherein the nonvolatile memory unit NVRAM comprises an N-1 memory block and a backup BACKUP block, and the N-1 memory block and the backup BACKUP block have the same memory space size; wherein the NVRAM mirror image storage unit is used for mirror image storage of data in a nonvolatile storage unit NVRAM, the NVRAM mirror image storage unit comprises N-1 storage blocks with the same storage space size, and the size of each storage block is the same as the size of the storage block of each nonvolatile storage unit NVRAM; the NVRAM read-write manager performs read-write operation on all data in the NVRAM mirror image storage unit through the NVRAM access interface; and the NVRAM and mirror image synchronization unit is used for synchronizing all data in the NVRAM and all mirror image data in the NVRAM mirror image storage unit.
Description
technical field [0001] The present invention relates to the technical field of semiconductor manufacturing, in particular to a data processing device and a processing method thereof, and more particularly to a fast and reliable non-volatile data storage structure and storage method. Background technique [0002] With the continuous improvement of performance and the continuous clarification of various application scenarios, industrial robots have been widely used in industries such as automobiles, electronics, metal products, plastics and chemical products. In the automation industry such as industrial robots, most of them need to support the execution of some kind of automation program. These programs may need to quickly generate or modify some data, and the frequency of modification is very high, which may reach more than 10 to 10,000 times per second. Moreover, these data often need not be lost after power failure. [0003] At present, if the above-mentioned high-frequen...
